OIC met plane at airport and transported me to the Narwhal. 12:00-13:00 Lunch. 13:00-17:00 There was some speculation that we may in fact depart for Eureka that same afternoon but by 15:30 it was confirmed we would be spending the night. Tuesday, October 8, 1996 Weather (in Eureka): Clear for most part, around sun. Temp: approx -25 C 9:00 am, est Departed Resolute via twin otter. Albert Maione and Wayne Davidson also on board, not to mention pilots... 11:30 am Arrived Eureka. On runway greeting commitee consisted of three musk-ox and a pack of wolves (4 adults and 3 pups). 12:30 pm Travelled to ASTRO. Albert briefed me on the Bohem FTIR system and we commenced taking measurements immediately. 16:30-1700 pm Returned to Eureka. Wednesday, October 9, 1996 Weather: Mostly clear around sun. Some cloud on horizon, below elevation of sun. Temp: approx -25 C 8:30-9:00 am Travelled to ASTRO. Stopped en route to take photos of musk-ox. 9:00-16:30 I continued taking Bohem FTIR measurements while Albert re-constructed the lab. 16:30-1700 pm Returned to Eureka. I drove. Thursday, October 10, 1996 Weather: Thin cloud; ice crystals/fog (15:00-16:00 GMT). Some clear patches around sun. Temp: approx -25 C. 8:30-9:15 am Albert briefed me on how to load water. I drove to ASTRO. 9:15-16:30 Took more Bohem FTIR measurements while Albert assembled various monitoring apparatus (instructions not included). Learned how to fill water tank. Also, began cleaning lab. Dusted and cleaned washrooms. 16:30-1700 pm Returned to Eureka. I drove. Friday, October 11, 1996 Weather: Clear around sun and most of sky. Thin cloud on horizon. Rest of sky clear and blue. Temp: approx. -20 C. 8:30-9:00 am I drove to ASTRO. 9:00-16:30 I continued taking Bohem FTIR measurements while Albert re-constructed the lab. 16:30-1700 pm Returned to Eureka. Saturday, October 12, 1996 Weather: Thin cloud over most of sky; quite dense in sun's path. Temp: approx -25 C. 8:30-9:00 am Travelled to ASTRO. 9:00-16:30 I continued taking Bohem FTIR measurements while Albert fine tuned the instruments. Cleaned lab. Wayne Davidson walked up to ASTRO from Upper Paradise. Shovelled snow. 16:30-1700 pm Returned to Eureka. Sunday, October 13, 1996 Weather: Overcast in morning. Clear around sun in afternoon. Temp: approx -25 C. 8:30-9:00 am Travelled to ASTRO. 9:00-16:30 Not a good day for measurements so I started out doing more cleaning. By 14:30, cloud cover had moved off so I took two scans of each filter with the Bohem FTIR measurements while Albert re-constructed the lab. Cleaned vacuum cleaner. Vacuumed bedrooms and kitchen. Albert showed me how to clear snow with the Track Truck. I proceeded to scrap the road bare and get rid of some of the piles left when the dozer had been through. Albert said that after this contract perhaps I could find a new career as a highway crew. Hmmm... 16:30-1700 pm Returned to Eureka. Monday, October 14, 1996, TURKEY DAY! Weather: overcast; snow, blowing snow, visibility less than half a mile. Temp: -15 C 8:30-9:15 am Filled water tank and I drove to ASTRO. 9:15-11:15 Bad day for observations so spent most of morning cleaning. Swept and mopped vestibule, kitchen, front hall. 11:15-13:00 Two military personnel made it up the hill with 2-wheel drive. Conducted a lab tour and served coffee. 13:00-15:30 Attempted to locate and print Reg's version of temperature check sheet. Prepared log. 15:30-16:15 Returned to WX station. I drove, this is, until Albert decided he wanted to go cross-country to check the transmitter field, at which point I relinquished control of the vehicle. We also stopped to re-fuel. Not a pretty sight with the 10-15 knot winds we were experiencing. Hence, Albert is sporting 'eau de diesel' yet again (or should that be still). 19:00-19:30 Albert stalled en route to lab. There seemed to be a problem with the fuel filter. Tuesday, October 15, 1996 Weather: Overcast. Snow and blowing snow. Visibility reduced to less than 1/2 mile. Temp: -15 C. 8:30-9:00 I drove to ASTRO. 9:00-10:30 Called Andrew Hunt (416) 739-4810, to try to sort out email. He said I could use PINE to manage my email. However, the system said, 'terminal type unknown' and won't support PINE. 10:30-12:30 Prepared temperature check sheet and conducted lab temperature checks. 13:00-16:00 Conducted rooftop instrument checks. Albert briefed me on the all sky camera. Wednesday, October 16, 1996 Weather: Overcast. Light snow. Temp: -12 C 8:30-9:15 4x4 received oil change and lube job by station mechanic. 9:15-9:45 Albert drove us to ASTRO. 9:45-10:30 Conducted lab temperature checks. Checked email. Still unable to send messages from the DOWS-01 server. Conducted roof checks with Albert. 10:30-11:30 Albert briefed me on back-up procedures as well as some of the history of ASTRO. 11:30-12:00 Tried email again. Made log entries. 12:30-16:00 Did back up for Daytona Beach Dave's spectrograph. Harold Beyer (met tech), Steve (military), and Cliff (military) dropped in for a visit. 16:00-16:30 I drove back to weather station. Driving was somewhat of a challenge as there was snow, blowing snow, snow drifts and reduced visibility, at times less than 50 m. Conditions were much clearer along the fjiord so we made it back with little difficulty. Saw same (presummably) musk-ox en route as we saw in morning and as we've noticed the past few days. It seems to be limping. Thursday, October 17, 1996 Weather: Overcast. Blowing snow and drifting snow. Temp: -20 C and dropping throughout the day. Visibility variable en route. By mid afternoon, visibility at ASTRO had dropped to less than 50 m. 8:30-9:40 I drove to ASTRO, that is until we got bogged down in deep drifts, just east of Upper Paradise. Albert managed to out manuover the snow and I took over again and made it to the top. 9:40-12:00 Did routine roof checks and temperature checks. FINALLY resolved problems with my email account and now have full access. We had been on the right track. We properly diagnosed that we had to change the terminal type, we just weren't aware how to do that. I started building an antennae with visions of TV reception dancing through my head. Realistically, I suspect it may augment the likelihood of ionspheric bounces of radio waves during the dark months. A military C-130 landed and departed with 3 of their 10 personnel who had arrived October 10. 12:30-15:00 Cleaned garage. (swept, vacuumed, & mopped) 15:30-16:00 Checked email. 16:00-17:00 I drove back to WX. We departed early anticipating some difficulty given the poor visibility and drifted snow. Nonetheless, the downward journey was mostly uneventful. Friday, October 18, 1996 Weather: Partly cloudy ( AC 7). Visibility 15 miles +. Temp: -20 C. Reduced visibility and drifted snow prompted Albert to remain at the lab overnight. Albert was up well before sunrise to clear the road near ASTRO so he could drive down to retrieve me. In the process, the hydraulic system for the plough on the Track Truck failed. All the fluid drained out, rendering the snow removal attachment useless and grossly impeding the manouverablity of the vehicle. Nonethelss, Albert managed to drive the ailing beast back to the barn. 9:30-10:15 I drove to ASTRO. 10:15-12:00 Conducted roof and temperature checks. Made log entries. Anamometer propellor frozen. Winds virtually calm. Albert continued my briefings on various instruments. 12:30-15:30 Tested and packed spare ASTRO computer for use at weather station. Fueled Track-Truck. In the process, the hose attached to the hand pump slipped off, dousing myself and the garage with diesel. (approx. 500-1000 ml. splilled forth) Cleaned the spill and prepped for the return journey. 15:30-17:10 Drove Track-Truck, with ailing snow plough, to weather station for repairs. 20:00-23:30 Returned to ASTRO with Albert to observe instrumentation during night conditions. EXCELLENT observing! Very clear sky. Also, hauled old Transport Canada short wave radio to ASTRO to see if we could receive anything with our new antennae. No luck. However, I did pick up a faint signal for an AM station on my CD player. 23:30-24:00 Returned to weather station. Saturday, October 19, 1996 Weather: Partly cloudy (AC 2, on horizon only). Winds light. Temp: -20 C. 9:30-10:00 Albert drove. Since the snow and blowing snow, there have been a few bad spots on the road, the worst being just east of Upper Paradise. By following the same ruts each trip, we have managed to carve out a passable trail. 10:00-11:00 Roof and temperature checks. 11:00-12:00 Loaded newly received 'automated' back-up software on spectograph computer and tested it. 13:00-16:30 In the process of testing this software, we a system glitch. The date is not updated on the computer. Albert continued to brief me on each of the experiments. Albert disproved Wayne's theory that we did not have the right on antennae for our radio by tuning in to a few different stations. 20:00-21:30 I drove a 20 tonne bull dozer to the air strip and watched the NWT Air stretch herc land. It's payload included 2 bags of mail, not to mention equipment to repair the runway lights. Sunday, October 20, 1996 Weather: Mainly clear (AC 1, on eastern horizon); Winds light, from the south. Temp: -20 C. 9:30-10:00 I drove 4x4 to ASTRO. Albert left early (7:30) with Track Truck to clear road. 10:00-12:00 Roof and temperture checks. Log entries. Checked email. Moved radio antennae from kitchen window to small port hole in lab 1. During the day, Albert managed to receive various short wave stations. 13:00-16:00 Attempted to calibrate spectrograph. We had a lengthy discussion about the software problems with the Polar Cameras. 16:00-16:30 I drove 4x4 back to Weather Station. 17:00-19:00 Did ASTRO laundry. Tested 'automated' back-up software for spectograph in Resolute. 19:00-19:30 I drove 4x4 to ASTRO lab. 20:00-21:30 Tested oven. (Baked cookies.) 21:30-23:30 Attempted to calibrate spectrograph using krypton lamp. I monitored the output screen inside the lab while Albert adjusted the focus on the roof. At the close of the evening, I had a close encounter with a IFO - (identified falling object). In a moment of desperation, the krypton lamp lept from the roof, crashing into the spectograph's monitor, leaving it's mark. The bulb shattered, exposing us to krypton gas, momentarily rendering our super powers useless. 23:30-24:00 Albert drove back to weather station. Monday, October 21, 1996 (long day) Weather: Mainly clear (AC 2); Winds moderate, from the south. Temp: -18 C. 8:30-9:10 I drove 4x4 to ASTRO. 9:10-10:30 Did roof and temperature checks. There was a small acumulation of ice crystals to brush off. Log entries. Checked email. 10:30-12:30 Prepared operator's manual for ASTRO lab. To be continued. (Autographed copies available upon request.) 13:00-15:00 Assisted Albert in debugging software for the polar cameras. SUCCESS! We finally got them running. 15:00-15:30 Albert gave me a brief, hands-on, tutorial of the sewage transfer process. The tutorial was curtailed upon discovery of a small brown stream flowing from the seam of the now not so intake tank on the back of the truck. We quickly stopped the pump, closed the valves, disconnected the hose and moved the truck out of the garage to minimize the sewage lagoon that was rapidly forming on the floor. Surprizingly, once the truck was out of the garage, the flow seemed to lessen. We made it to the sewage dump with approximately half a tank full of effluent. 15:30-16:15 Albert drove the truck to the sewage lagoon and I did the honors of opening the valve to release the load. Oddly enough, I seem to recall when asked, Hans had indicated that the sewage transfer process was NOT a messy process. Things that make you go, Hmmm... Albert arranged with Jobie and Greg (station mechanic and heavy equipment operator) that we would take their truck tomorrow while they investigated our leaky sewage tank. 18:00-18:30 Returned to ASTRO. Partly to escape the rather intense, but emanently pointless discourse around the bar about government spending and partly to continue with my familiarization of the experiments. I have found these last few days of trouble-shooting with Albert to be quite interesting and very informative. It's often very helpful to know the history. 18:30-21:30 Obtained calibration files from MIRA spectrograph system and ftp'd them to John Pesce for review. Sent email to John Pesce requesting further info as to how to view specta in real time so we can more finely adjust the focus of the spectrograph. Discussed various aspects of ASTRO operations with Albert. Primarly our discussion focused on communications with respect to lab operations. 21:30-22:00 Albert drove back to weather station. Tuesday, October 22, 1996 Weather: Fog at weather station. We 'broke free' at approx. 30 m. Partly cloudy (AC 5); Winds moderate (10 knots), from the south. Temp: -17 C. 8:30-9:15 Albert and I stopped in at the garage to discuss pending repairs to our sewage tank. There appears to be a crack where the outlet pipe joins the vessel. There was some discussion as to the source of the damage. It was suspected to have happened when the truck was rolled last spring. (Other things that make you go Hmm...) In lieu of our beaten up red rocket, we were allocated the OIC's brand new Chevy 4x4. What a treat to drive! 9:15-10:00 Roof and temperature checks. Noticed that the anemometer was turning, but not as fast as it should have been due to an accumulation of snow, which Albert dislodged. Log entries. Checked email. 10:00-12:00 Instrument checks. Made daily entries into instrument logs. Downloaded met data from data logger. 12:30-16:00 Shut down FTIR system for the season. Tested calibration system for Polar Cameras. Sent email message to Dave Steele regarding Polar Camera calibration. Albert received a carbon copy of a message that Dave sent to me, within minutes. I did not actually receive the message until 9:00 pm, well after the calibration was completed. Albert and I spent some time attempting to send each other messages to sort out what was happening. It seems my mail is being held up somewhere en route. I tried to contact user support at 16:36 est, but they shut down at 16:30. 16:40-17:00 I drove the Chevy 4x4 back to the weather station and parked it. Even with mere inches to spare, with mirrors and no tanks obscuring the view, it was much more manoeverable. 17:45-18:00 (estimated time) Power failure. 18:00-18:30 Albert and I returned to the lab just in time to confirm that the back-up generator had in fact turned on. 18:30-19:30 Albert briefed me on how to re-start the experiments in the event of a power failure. 20:00-21:00 Spent some time trying to sort out my email system. We've discovered that it takes approx. 6 hours for me to receive a message!! (This is NOT acceptable when doing time critical calibrations, as we were endeavouring to do this afternoon.) 21:00-22:30 Albert and I had planned to make another attempt at focusing the Spectrograph. This time Albert tried something different, and the results were quite satisfactory. He placed the source 2.5 feet away from the spectrograph. Previously, he had placed the source directly in front of the dome, thus weakening the signal. I subsequently ftp'd the new calibration data to John Pesce for review. 22:30-23:15 Log entries (today's), while Albert tied up some loose ends. 23:30-24:00 Albert drove back to weather station. Wednesday, October 23, 1996 Weather: Overcast. Winds light and variable. Temp -14 C. Snow overnight. 8:30-9:15 Albert refueled the 4x4 and we went to ASTRO. 9:15-10:00 Roof and temperature checks. Checked email. Log entries. Everything working properly. 10:00-12:00 Phoned Sean Healy at (416) 739-4310 regarding delays in receiving email. For a test, I asked him to send a message to myself and cc it to Albert. I received my message slightly before Albert. However, when Albert sent a message at 15:24 z to himself and me, he received his message within a minute and mine arrived at 15:56 z. I called Hans to confirm whether or not he'd sent a message to me. (Sean had mentioned a message from Hans that had been sent last night.) 12:30-13:00 Reviewed previous night's ASC tape. Hans phoned. Albert mentioned the sewage transfer escapade, among other things. 13:00-14:00 I worked on Astro Lab Operator's manual while Albert cleared the driveway. 14:00-16:30 Albert and I worked on the Astro Lab Operator's manual. He continued briefing me with respect to the instrumentation. We discussed whether or not to run the Brewer on a schedule or operate it manually. 16:30-17:00 I drove back to the weather station. The road has been very slippery the past few days because of the warm weather. 19:00-19:30 I drove back to Astro. We had hoped to be able to do a moon siting on the Brewer but the sky conditions were uncooperative. 22:30-23:00 I drove back to the weather station. Thursday, October 24, 1996 Weather: Overcast; light snow. Winds south at 3 knts. Visibility 15 + mi. Temp -14 C. Snow overnight. 10:30-11:15 I drove to Astro. 11:15-12:30 Roof and temperature checks. Instrument log entries. Noticed that the anemometer was turning, but not as fast as it should have been due to an accumulation of snow, which Albert dislodged. Noticed 'evidence' that a fox had visited the roof of ASTRO. Log entries. Checked email. 13:00-15:00 Worked on ASTRO operator's manual. Pumped a load of effluent to repaired removal tank. 15:00-15:45 I drove to sewage dump and proceded to empty load. 15:45-17:00 Reviewed ASTRO manual to ensure that I was fully familiar with all aspects of lab operation. Discussed a few points with Albert. 18:00-22:00 Returned to ASTRO. I assisted and stood safety while Albert repaired the roof hatch for one of the LIDAR's. We pumped out another tankful of effluent as well. 22:00-22:30 Albert drove to the sewage lagoon and we dumped load 2 for today. 23:15-23:45 (approx.) We returned to ASTRO again (third trip today). 23:45-24:15 The full moon reappeared from behind cloud and we were intent on making a proper siting. As it turned out, the siting was very close to being right on. Nonetheless, this confimed it. We pumped a third load of effluent, hopped in the truck, ready to discover the truck was insistent on a rest. (It wouldn't start as it needed to cool down.) 24:15-01:45 As we had time to wait anyhow, we opted to initiate back-ups. We completed both back-ups on the MSP and initiated first back-ups on the spectrograph and the 4-MI. 01:45-02:30 Albert drove back to the sewage lagoon and we dumped our third load. Given the length of the day, we made a corporate decision to start later on Friday. Friday, October 25, 1996 Weather: Clear. Winds calm. Visibility 15 + mi. Temp -16 C. Cloudy to clearing overnight. 9:00-11:00 Albert did a solo trip to Astro to remove the last load of effluent while I took care of a few administrative matters. 11:00-11:30 Went to ASTRO. 11:30-15:45 Initiated second back-ups. Roof and temperature checks. Checked email. Completed back-ups. Prepped data and equipment for shipment south with Albert. 15:45-16:15 Albert drove back to weather station. 16:15-16:30 Prepped Bomem crates for shipment. 19:30-20:00 Saw Albert to the airport. Helped OIC unload groceries. Full moon tonight. Hopefully the Brewer is working without me. Saturday, October 26, 1996 Weather: Mainly clear. Winds NE at 25 gusting to 30 knts. Visibility 15 mi. Temp -22 C. Mainly clear overnight. 10:00-10:30 I drove to Astro. The calm below (at WX station) bore no resemblance to the strong winds above. Consequently, driving the last 100 m. of road was a bit of challenge. 10:30-11:45 Roof and temperature checks. Completed instrument logs. Note: A small quantity of snow had blown into the lab entrance from the door that exits to the stairway. There must be a small gap between the weather stripping and the door frame or the door wasn't closed tightly. 12:15-13:00 Log entries (Thursday pm to now). 13:00-14:15 Checked email. Discovered web site on ASTRO lab. Read about ASTRO history. 14:15-15:45 Seeing that the road was questionnably passable due to newly formed drifts, used Track Truck to clear road. Got stuck in process. Had to resort to shovelling but I managed to get unstuck. Now am warming up pending return trip. Checked weather prior to leaving, frying mouse in the process. 16:30-17:00 Returned to weather station. Sunday, October 27, 1996 Weather: Mainly clear. Winds NE at 10 knts. Visibility 15+ mi. Temp -21 C. Mainly clear overnight. 10:30-11:15 I drove to Astro. It several tries before it would turn over. 11:15-12:45 Roof and temperature checks. Completed instrument logs. Borrowed mouse from FTIR lab to use on ASTRO10. It worked O.K. 12:45-14:15 Checked email. Prepped ASTRO shopping list for Albert. 16:00-16:30 Drove back to Weather Station. En route, I was able to receive a British AM radio station, all the way back. Monday, October 28, 1996 Weather: Clear. Winds NE at 20-25 knts. Visibility 15+ mi. Temp -22 C. Clear overnight. Full moon Note: The direction for the anemometer is not working so I have been approximating. 8:45-9:15 Drove to Astro. 9:15-10:45 Roof and temperature checks. Completed instrument logs. Checked email. Made log entries. 10:45-12:30 Checked out CD rom on 'Born' (Mira's home). Upon further investigation, noticed one of the 'talking prompts' has size of 50 k. That is, it's not looking likely that our wimpy transfer rate could support live radio. 13:30-15:00 Plowed road. 16:30-17:00 Drove back to Weather Station. Received an assortment of AM radio stations en route. Tuesday, October 29, 1996 Weather: Clear. Winds E at 10 knts. Visibility 15+ mi. Temp -18 C. Clear overnight. Waning moon. 8:45-9:15 Drove to Astro. I've noticed the ArCtic hare seem to be trained now. They seem to run the other way when they here our truck now.... 9:15-11:15 Roof and temperature checks. Completed instrument logs. Checked email. Made log entries. Have opted to change date on Spectrograph file just prior to leaving the lab. That way, in case I get weathered in for one day, it may be able to handle it. 16:30-17:00 Returned to Weather Station. Received a British radio station en route. The 4 wolves were around when I returned. Wednesday, October 30, 1996 Weather: Mainly clear. Winds NE at 4 knts. Visibility 15+ mi. Temp -15 C. Clear overnight. Waning moon. 8:45-9:15 Drove to Astro. Received CKXM, 1200 am, from Victoria, B.C., en route. Tried to see if I could pick up anything on my radio at the lab. Nothing. Noticed evidence that Fred visited overnight. 9:15-10:27 Roof and temperature checks. Completed instrument logs. I had just started to rewind the ASC tape when the lights went out. 10:27-11:40 POWER FAILURE. Back-up generator ran for 1.5 hrs, off at 16:54z. Note: Apparently there are problems with the controllers for the 3 generators back at the weather station. The generators are mechanically sound but there is either a programming or electrical problem, which by the sounds of it, neither Jobie or Gregg quite have the expertise to resolve. Consequently, we may be having more power failures. The spectrograph continued to run on it's back-up power, during the power outage. The 4-MI computer hung up while re-booting at the screen that read: Microsoft Interlink Version 1.00 Connection NOT established Drive letter redirected : 1(E:) No printer ports redirected Periscope Data REad 123456789ChannelA initialized 12 At 17:00 z, (20 minutes after power on), I hit the computer 'reset' button. The system reset O.K. 11:40-13:00 Instrument log entries. Checked email. Made log entries. 13:45-15:30 Groomed road. (It was getting kind of narrow where the large drifts were. 15:30-16:30 Checked email and responded. 16:30-17:00 Returned to station. Thursday, October 31, 1996 BOO! Weather: Overcast. Winds ESE at 15-20 knts. Visibility 15 mi. Temp -16 C. Mainly cloudy overnight. Waning moon. News: Due to problems with the controller for the weather stations power plant, there will be a flight from Resolute on Monday, November 4. 9:00-9:30 Drove to Astro. Received ABC from Fairbanks (I think). I did manage to pick up a very faint signal on my radio, at the very top end of the am band. 9:30-11:30 Roof and temperature checks. Completed instrument logs. Read over some of the detailed instructions for each of the experiments. The spectrograph was not operating when I arrived. The computer screen showed only the console, and it was blank. (Normally, the camera window, cooler control, console and two plots are on screen.) I looked at the data directories and determined the last file was ek103096.327, time: approx 9:00 z. I re-started Mira and continued with file ek103096.328 and it appears to be functioning normally. 11:30-13:30 Log entries. Checked email and responded. Observed Polar Camera back up. 16:00-17:00 Shut power off to 4MI system (1625z) at power bar and back on, to reset the system. Data had not looked quite right since power failure. Noticed that spectrograph had stopped taking observations again. On further investigation, the reason was apparently lack of memory due to a file allocation error. When I ran SCANDISK, it fixed the problem and stored 340,000,000 bytes of ?? into a file called Filechk.001 Initiated spectrograph back-up 1. 17:00-19:00 Sent email regarding spectrograph memory. Later, tried to check email but my server was down. 19:00-19:05 Initiated second back up. Checked with weather office to determine whether or not cloud cover would be expected to continue overnight. Decided that it wasn't likely to clear, consequently opted to leave. 19:45-20:15 Returned to weather station. Friday, November 1, 1996 Weather: Partly cloudy (4/10 AS). Winds SE at 5-7 knts. Visibility 15 mi. Temp -14 C. Partly cloudy overnight (6/10 to 4/10 AS). Waning moon. 8:45-9:15 Drove to Astro. 9:15-11:00 Roof and temperature checks. Completed instrument logs. Viewed ASC tape. Not much discernable, due to brightness of moon. 11:00-15:30 Checked email. Backed up 4MI data, (2 copies) and spectrograph's mystery file (2 copies). Sent John Pesce message re: spectrograph. John replied. 15:30 Wayne Davidson arrived at the lab, after walking up from Upper Paradise. (This is part of weekly fitness program.) 15:30-16:30 Finished back ups. Checked email. 16:30-17:00 Returned to weather station. 18:30-19:00 Replied to John Pesce email, re: spectrograph. Saturday, November 2, 1996 Weather: Mainly clear. Wind ESE at 6 knts. Visibility 15+ mi. Temp -15 C. Mainly clear overnight. Trace of precipitation. 10:00-10:30 Refueled 4x4 and drove to Astro. 10:30-12:30 Roof and temperature checks. Completed instrument logs. Checked email. 12:30-13:30 Sorted through some of the maze of empty boxes and marked some for extinction. Vacuumed. 14:00-15:00 Cleaned washroom, mopped floors. 16:30-17:00 Returned to weather station. Sunday, November 3, 1996 Weather: Mainly clear. Wind E at 11 knts. Visibility 15+ mi. Temp -15 C. Mainly clear overnight. Trace of ice crystals. 9:30-10:00 Obtained drinking water and supplies. 10:00-10:30 Drove to Astro. Invited Bernadette to come along, to have a holiday from Eureka. 10:30-12:30 Roof and temperature checks. Completed instrument logs. Checked email. 13:30-14:30 Returned to weather station. Took Bernadette for a site-seeing tour of Eureka International (airport). Monday, November 4, 1996 Weather: Cloudy. Wind E at 17-20 knts. Visibility 15+ mi. Temp -16 C. Increased cloud overnight. 8:30-9:00 Drove to ASTRO. 9:00-11:30 Roof and temperature checks. Completed instrument logs. Discovered that Brewer had reached main menu screen, and was now apparently tracking the sun. Noticed yet another quirk with the Spectrograph. I've noticed that when I type 'time' at the DOS prompt, followed by 'enter', this initiates the Iomega back up software. This has happened twice, on MONDAY, Oct. 28 and MONDAY, Nov. 4. When I tried to reproduce the result, it simply displayed time. Last Monday, I decided that I probably had hit another key. This week, I've developed a new theory. I think that there may be a command somewhere, directing the system to do a back up on Monday. I viewed the ASC tape. There was some rather distinct auroral activity between 600-700z as well as a few less noticiable events at approx. 0030 and 230 z. 11:30-12:00 Email 13:00-16:00 Ploughed snow. 16:00-16:30 Instrument checks. With the rapidly disappearing twilight, the instruments are now taking observations before I depart the lab. Tuesday, November 5, 1996 Weather: Overcast. Wind SE at 5-7 knts. Visibility 8 mi. in light snow. Temp -14 C. Increased cloud and light snow overnight. Note: Snow stopped and visibility improved to 15+ mi by 1800z. 8:30-9:00 Loaded boxes. Drove to ASTRO. 9:00-10:40 Roof and temperature checks. Completed instrument logs. 10:40-11:20 Investigated Back-Up Scheduler on Spectrograph. Within Back up Scheduler menu of Iomega software, deleted back up events pending for upcoming Mondays. The Scheduler itself remains active however there are no events scheduled to iniitate. 11:20-12:30 Unpacked boxes. Checked email. 13:30-14:30 Set up Brewer printer. 14:30-15:00 Stored new shipment of supplies. 15:00-16:15 Ploughed snow. We now have two lanes, instead of one, beside ASTRO. 16:15-16:30 Checked intstruments. 19:41-20:05 Power Outage at Eureka. 22:30-23:30 Drove to ASTRO, accompanied by Wayne. Stopped en route at Skull Point to reset the satellite equipment and to try and get the TV signal back. 23:30-24:15 Checked instruments. The MSP time and date were incorrect, and SCAN MODE was disabled, which I corrected. The 4MI data looked 'off'. (The signal to noise ratio was about 30% smaller than usual.) I switched the power off and on at power bar to reset. I checked the generator's fuel tank. The guage on top reads empty. Will investigate further. In the meantime, Wayne moved the full fuel barrel in place, near the tank's inlet. 24:15-24:45 Returned to weather station. Wednesday, November 6, 1996 Power Failure: 00:41-01:42z according to ASC; Generator ran 1.2 hr. This was an 'unplanned outage'. As a result of the outage, we lost TV at the station. It needed to be reset at Skull Point. Weather (1600z): Thin overcast. Wind NNE at 3-5 knts. Visibility < 1/4 mi. in fog, rapidly dissipating. Temp -19 C. Overcast overnight and trace of precipitation. 9:45-10:30 Refueled 4x4 (80 l), while waiting for traffic to clear on road to ASTRO. (Dave had gone to Skull Point to reset the TV.) Drove to ASTRO. 10:30-13:00 Roof and temperature checks. Completed instrument logs. Re: Brewer When I did my checks this morning, I noticed that the date had not updated. (I suspect this could be a side effect of the power failure.) As the moon is now well below 30% disk, I began daily hgslrsdt today. The printer spewed reems of information overnight - mostly the daily summaries, as I had not yet exited from euwinter. One of the first things it printed was: Brewer clock read did not succeed [1] ( 0, 53, 127, ) 13:00-14:00 Checked email. When I spoke to Greg this morning, he said the generator's tank had been 3/4's full, according to Albert. I manually checked the level in the tank, and estimate it's somewhere in between. 14:00-15:30 Emailed back and forth a few times with Andrew Hunt to try to sort out proposed changes to the DOWS 01 server.. Andrew suggested that I could use Eudora. However, when I attempted to ftp the executable file, I was denied permission. Then, once he change my parameters, the server 'timed out', presumably because our transfer rate is too slow. Will try at a later time in the day. The Eudora file is just over 2,000,000 bytes. 18:15-18:30 Checked instruments. 18:30-19:00 Returned to weather station. Thursday, November 7, 1996 Weather (1430z): Mainly clear (trace of SC on eastern horizon). Wind E at 5 knts. Visibility 15+ mi. Temp -18 C. - Mainly clear overnight. 8:45-9:15 Discovered the 4x4 was already outside and running. Since Kevin arrived on Monday, Greg and Jobie have been very busy. Drove to ASTRO. 9:15-11:15 Roof and temperature checks. Completed instrument logs. Everything appears to be working O.K. this morning. I viewed the ASC tape and I noticed something that looked like a 'shooting star'. There was only one brief auroral episode at approximately 6:00z. 11:15-11:50 General log. 11:50-12:30 Checked email 13:30-16:30 Downloaded Eudora from Downsview server (took 2 hours to get 3 files!) Conducted misc. administrative duties. Prior to returning, I checked the instruments. When I got to the Polar Camera, I hit control and the right arrow. The system didn't display the images after several seconds so I hit it again. This caused an unfamiliar series of displays. I eventually opted to reboot the system to ensure everything was as it should be. 16:30-17:00 Returned to weather station. Friday, November 8, 1996 Weather (1500z): Partly cloudy (ASTRO lab poking out of a layer of stratus); Wind E at 14 knts. Visibility 15+ mi (from roof; fog layer begins just below elevation of ASTRO). Temp -24 C. - Mainly clear overnight. 8:30-9:10 Drove to ASTRO. 9:10-11:15 Roof and temperature checks. Completed instrument logs. Everything appears to be working O.K. this morning. I viewed the ASC tape and I noticed something that looked like a 'shooting star'. No apparent auroral activity. Initiated Backups for Spectrograph and 4MI. Tried to determine whether or not 4MI back-up appends to tape or overwrites... 11:15-12:00 General log. Checked email. 12:00-14:00 Initiated back-ups. Cleaned up email directories. 14:00-16:30 Installed Eudora and tested it. Completed back ups. 16:30-17:00 Returned to weather station. Saturday, November 9, 1996 Weather (1600z): Partly cloudy (7/10 SC, AC); Wind N at 15-20 knts. Visibility approx. 2 mi; Temp -27 C. - Partly cloudy and snow overnight. 9:45-10:30 Obtained drinking water and drove to ASTRO. 10:30-12:15 Roof and temperature checks. Completed instrument logs. ASC - viewed tape. Some auroral activity between 2300-200z. From 700z onward, sky mainly obscured by cloud. Brewer - issued hgslrsdt. - Standard diode offset apparently incorrect. Check micrometer mechanism and reset by hand. I plan to hold off on this, until the snow stops. (Excess moisture inside the Brewer would not be desirable.) 12:45-13:30 General log. Checked email. Received messages from John Pesce (Spectrograph) and Dave Steele (Polar Camera) that they have reviewed the first set of data sent out and are happy with the results. 14:20 Wayne arrived. He walked up from Upper Paradise again (his weekly trek). He was very pleased to report he cut his time to 60 minutes. 14:20-16:15 Tried to resolve problem with Brewer. Issued a te, to discover the instrument temperature was -2 C, much lower than it had been a few days earlier. Although, the ambient temperature was significantly colder today. Also issued the re command as well as the sl command. Confirmed that the mercury lamp is coming on O.K. 16:15-16:45 Returned to weather station. Sunday, November 10, 1996 Weather (1600z): Mainly cloudy (9/10 SC, AC); Wind S at 5-6 knts.

Completed instrument logs. ASC - viewed tape. Sky obscured until 0000z. Some auroral activity between 900-945z. Brewer - Brewer temp 1 C. - Issued hg but experienced same problem as yesterday: Standard diode offset apparently incorrect. Check micrometer mechanism and reset by hand. 12:45-13:15 Checked email. 13:15-16:00 Redid address book. Resent message to Hans, hoping that it would work this time. Since switching from Eudora from Pine I have had a number of returned messages. Apparently the addressing is slightly different. 16:00-16:30 Returned to weather station. Monday, November 11, 1996 Weather (1800z): Overcast; Wind NNW at 15-20 knts. Visibility 1/2 mi in snow and blowing snow; Temp -20 C. - overcast and snow overnight. 10:30-12:00 Remembrance Day service. 12:30-13:00 Checked oil on 4x4. OK. Noticed that left mirror is now on. Drove to Astro. 12:30-14:30 Roof and temperature checks. Completed instrument logs. ASC - viewed tape. As expected, nothing to see. Sky obscured and mirror covered with snow. Brewer - Brewer temp 4 C. Postponed resetting micrometer again, due to falling and blowing snow. 14:30-16:30 General log and checked email. 16:30-17:00 Returned to weather station. Tuesday, November 12, 1996 Weather (1400z): Mainly clear (trace SC to west); Winds calm; Visibility 15+mi; Temp -19 C. - overcast and snow overnight. 8:00-9:00 Gathered grocerie, refueled 4x4 (73 litres) and drove to Astro.

Postponed resetting micrometer again, due to falling and blowing snow. 10:30-11:00 General log and checked email. 11:00-14:45 Trouble-shooting problem with Brewer. 14:45-16:15 Ploughed snow. 16:15-16:45 Trouble-shooting Brewer problem. 16:45-17:15 Returned to weather station. Wednesday, November 13, 1996 Weather (1500z): Mainly clear (trace SC to west); Wind W at 25 knts gusting to 30; Visibility 15+mi; ground vis. (3' depth), reduced to 0 in blowing snow; Temp -20 C. - some cloud overnight. 9:00-9:40 Drove to Astro. Rather eventful trip... Got a bit bogged down at kilometer 8, but managed to manoever out of it. 9:40-11:20 Roof and temperature checks. Completed instrument logs. MSP - was emitting periodic audio alarm, each time it access hard drive. 11:20-12:40 Trouble shooting Brewer problem. Prism rotates up for ZS but remains stationary for RE and lamp tests. Manually rotates prism down to do standard lamp test. 13:15-15:30 Refueled track truck and ploughed driveway. 15:30-15:45 General log. 15:45-16:30 Checked email and rechecked instruments. 16:30-17:00 Returned to weather station. Thursday, November 14, 1996 Weather (1500z SA from 2322 at Eureka Weather Station): 6/10 opacity; 8/10 amount; E80 BKN; Vis 10 mi in IC; Wind from 10 at 3 knts ; Temp -23.5 C; AC 6 - mainly clear overnight; ice crystals and ice fog. 9:00-9:30 Attempted to drive to Astro with 4x4. Got bogged down at kilometer 8. Called weather station to request rescue. 9:30-10:30 Shovelled out around 4x4 while waiting for rescue. 10:30-11:00 Greg accessed the situation and decided the loader would be required to pull out the 4x4. The loader was N/S (non-serviceable). Cleaning the runway for tomorrow's plane takes priority. Therefore, I will remain at weather station pending available transportation. 2335-2340z (approx) Power Failure at Eureka weather station. Friday, November 15, 1996 Weather (1500z SA from Eureka Weather Station): 0/10 opacity, 0/10 amount; 80 FEW; Vis 15 mi; Wind from 290 at 6 knts Temp -18.8 C; AC TR - cloudy to clear overnight; ice crystals. 13:00-14:00 Assisted Tom McLean with ice observation and snow survey. 14:00-15:00 Dave Urquhart drove me to Astro with AES Track Truck. 15:00-16:00 Backed up MSP data from Oct 25 - Nov 3. Changed ASC and PoCa data tapes. Cancelled 'Power Failure Screen' on ASC. Reset MSP time (incorrect, presumably since power failure previous night) Collected data tapes for shipment. 16:00-17:00 Returned to weather station. 18:00-18:15 Prepared data for shipment south. Saturday, November 16, 1996 Weather (1500z SA from Eureka Weather Station): CLR; Vis 15 mi; Wind from 060 at 3 knts; Temp -23.6 C - mainly clear. Greg and Jobie were going to clean the road today and retrieve the 4x4. But the winds were too high, so snow removal was postponed. In the meantime, the OIC gave me authorization to use the AES Track-Truck. I had to wait until Greg completed installation of a large battery in this vehicle (to prevent starting problems). 14:00-14:30 Refueled AES TT and prepped to go. 14:30-15:30 Drove to Astro. 15:30-20:30 Backed up 4MI, Spectrograph and MSP data. Caught up on instrument logs. 17:30-18:30 Cleared snow, (while data was backing up). 19:00-20:00 Cleared snow, (while data was backing up). TT got bogged down in soft snow. Tried to shovel it out, but it only dug itself deeper. 20:30-21:00 Checked instuments and email. 21:00-21:45 Returned to weather station. Sunday, November 17, 1996 Weather (1500z SA from Eureka Weather Station): 8/10 opacity, 10/10 amount; 100 FEW E80 OVC; Vis 5 mi in IC, BS; Wind from 150 at 11 G 17 knts; Temp -15.5C - clear to cloudy to clear and blowing snow, overnight. Road cleaning postponed again due to high winds and reduced visibility. 'Weathered in' for the day at Eureka. Monday, November 18, 1996 Weather (2030z): Overcast; Wind E at 7 knts.

Kept getting 'READ FAULT ERROR' for data files E96B12.BFK, E96B13.BFK, E96B14.BFK. Backed up two all MSP except those three files. 18:00-18:30 Checked email. 18:30-19:30 (approx) Returned to weather station. Tuesday, November 19, 1996 Weather (2000z): Mainly overcast; Wind W at 6 knts; Visibility 15+mi; Temp -11 C. - cloudy and very windy at Eureka weather station, overnight. 9:30-10:00 Collected weather information from 2322's at weather station to 'fill in the blank' for the days I was not at Astro, or only here briefly. 10:00-13:00 Assisted with Gregg and Jobie in recovering the 4x4. The plan was that I would drive it back once they pulled it out. Unfortunately, 5 days in the wind was a bit much and it refused to start. 13:30-14:00 Checked oil and refueled TT #2 (16 litres). 14:00-15:00 Drove to Astro. 15:00-16:00 Roof and temperature checks. Completed instrument logs. 16:00-17:00 Checked email. 19:00-20:00 Returned to weather station. Wednesday, November 20, 1996 Weather (1600z): Mainly clear (trace SC to east); Wind NE at 20 knts; Visibility 15+mi; Temp -18 C. - overcast, snow and blowing snow to clearing, overnight. 9:00-9:40 Checked oil and refueld TT 2 (15 litres). 9:40-10:40 Drove to Astro, via TT #2. 10:40-12:00 Roof checks, temperature checks, instrument checks and log entries. Note: Some snow drifted inside garage. All rooms on north side of building 10-20 degrees F cooler than usual. Kitchen temp = 49 F. Checked heaters. All feel warm to touch. Checked circulating fans in pump room. All 4 are on and running OK. Kitchen temp = 59 F, two hours after my arrival. Concluded that strong winds were creating substantial draft from garage. 12:00-13:00 Viewed ASC tape. Adjusted moon shield 5 degrees clockwise. 13:00-14:00 General log. Caught up on previous days (Nov 13, 14, 18-19). 13:45 This just in... The 4x4 lives! Greg called to say they got it running again. 14:00-14:30 Disconnected Brewer from tracker. 14:30-14:45 Caught up on general log (Nov. 15, 16). 14:45-15:45 Checked email. 15:45-16:30 Brought Brewer in. Renamed Spectrograph file, and changed date. Checked instruments. 16:30-17:30 Returned to weather station. Thursday, November 21, 1996 Weather (1530z): Mainly clear; Wind NNW at 13 knts; Visibility 15+mi; Temp -14 C. - cloudy, overcast to clearing, overnight. 9:00-10:00 Refueled TT 2 (13 litres). Drove to Astro. 10:00-12:00 Roof checks, temperature checks, instrument checks and log entries. Note: Building temperatures back to normal. 12:30-14:00 Fed Brewer cables from roof throught hatch. They seemed to catch on something in the hatch. 14:00-1500 Checked email. 15:00-16:00 Tried to untangle Brewer cables. 16:00-16:15 Log entries. 16:15-16:30 Checked instruments. 16:30-17:10 Returned to weather station. 17:45-19:00 Drove OIC to Skull Point to fix TV. The transmitter had gone off line. Note: TT #2 had flat tire and was trailing exhaust pipe. Friday, November 22, 1996 Weather (1700z): Clear (TR of SC); Wind N at 20 knts; Visibility 15+mi; Temp -12 C. - mainly clear overnight. 9:30-10:30 While waiting for repairs to TT, cleaned windows on 4x4 and checked emergency supplies. The small pack contains first aid supplies, candles and matches. There is a blanket and a parka behind the back seat. However, there was no food or drinks. I collected some food rations to keep in the 4x4 and also in the TT. The OIC recommended that we should also have a sleeping bag in each vehicle. He said "Hans has lots of money. You just have to tell him what to buy." 10:30-11:15 Refueled TT #2 (21 litres). Waited for Met tech to do ice survey. 11:15-12:00 Drove to Astro. 12:00-12:15 Initiated Spectrograph back-up. 12:15-13:15 Roof checks, temperature checks, instrument checks and log entries. Note: ASC Moon Shield blew off in high winds at 0203 z. 13:15-17:00 Backed up 4MI data (2 copies) and Spectrograph (2 copies). 13:45-14:30 Checked email. 14:30-15:30 Attempted to retrieve moon shield. It had landed on the snow beneath the metal grating. After several attempts in 25 knt winds, I opted to contruct a temporary replacement from cardboard and duct tape. 15:30-15:45 Spoke to OIC to ensure their would be adequate transportation available by November 27 for incoming Astro visitors. OIC said either the road would be cleared or a TT with passenger space would be available. 15:45-17:00 Constructed and attached temporary moon shield. Checked email. Checked instruments. 17:00-18:00 Returned to weather station. Saturday, November 23, 1996 Weather (1600z): Mainly Clear (TR of SC); Wind N at 25 knts; Visibility 15+mi; Temp -18 C. - mainly clear overnight. 9:30-10:00 Gathered groceries for Astro. Checked oil. Refueled TT #2 (17 litres). 10:00-10:45 Drove to Astro via TT # 2. 10:45-12:15 Roof checks, temperature checks, instrument checks and log entries. Note: Viewed ASC video. The temporary moon shield blocked the moon OK. However, when the moon shield is supposed to be 'off' it is still visible in the line of view of the camera. Will attempt to adjust, pending winds. Due to unusually warm temperatures and strong winds, the snow is rapidly disappearing, and that remaining, is turning to ice. As such, they may attempt to clean the road today. HURRAY! (I miss my AM radio stations...) 12:30-13:00 Re-organized kitchen cupboards, in preparation for visitors. 13:00-13:30 Log entries (22, 23). OIC called re: current weather conditions at Astro. 13:30-14:00 Retrieved Brewer cables from hatch. 14:00-15:00 Brewer diagnostics. sl prism roatated downward. zs prism rotated upward. hg prism rotated downward. Brewer appears to be working OK at room temperature. Moved Brewer to foyer, to reduce instrument temperature. Plan to repeat tests with cool instrument. 15:00-16:00 Checked email 16:00-16:30 With Brewer temp now 0 C: zs prism rotated upward sl prism remained stationary Allowed Brewer to re-heat. 16:30-17:30 Returned to weather station, via Fjord. Sunday, November 24, 1996 Weather (1600z): Clear; Wind N at 11 knts; Visibility 15+mi; Temp -17 C. - mainly clear overnight. 9:45-10:15 Checked oil. Refueled TT #2 (17 litres). 10:15-11:15 Drove to Astro via TT # 2 with Bernadette. 11:15-12:15 Roof checks, temperature checks, instrument checks and log entries. Re: ASC Shutter closed when I arrived. Viewed ASC video. The shutter closed at 0536z. The temporary moon shield is still holding. 12:15-13:15 Retrieved moon shield from beneath grating on roof. Re: Brewer temp now 13 C sl prism did not move, continued to look up. 13:15-14:30 Returned to weather station (to get Bernadette back in time to prepare dinner). Note: Greg and Jobie cleared the road today and pushed the TT with the snow plough back into the garage. After being stuck since last Saturday, it wouldn't start. Monday, November 25, 1996 Weather (1500z): Fog; Wind NW at 6 knts; Visibility 1/8 mi; Temp -27 C. - clear to overcast, ice crystals and snow, overnight. 8:30-9:00 Gathered groceries and other supplies. 9:00-9:30 Drove to Astro 4x4. Was able to pick up 1530 am, KCJB (approx.) from the west coast of US. 9:30-11:30 Roof checks, temperature checks, instrument checks and log entries. Re: MSP Musical alarm was going when I arrived. Renamed today's data file. Alarm started again within an hour. Renamed data file again and alarm stopped. Re: ASC Shutter still closed when I arrived. Video tape counter had only advance 11 seconds. The temporary moon shield is still holding. Re: Brewer temp now 14 C Note: Not sure how prism is oriented (opening not visible). The last command I issued yesterday was sl. At that time, the prism had not moved so I aborted the test. The prism was pointing up when I left. zs No apparent movement of prism. sl prism rotated 180 (approx), ending up pointing forward (not down); Aborted measurement re prism moved sl not sure if prism moved. (It ending up pointing down, and did the test O.K.) 11:30-12:00 Updated weather log and general log. 12:30-13:30 Cleaned above kitchen cupboards and stove top. 13:15-14:15 Attempted to reattach moon shield. 14:15-15:00 Checked email. 15:00-16:00 Cleaned kitchen cupboards and bathroom. 16:00-16:45 Greg called to see if the Track Truck would start. It did. Re: ASC Attempted to re-boot computer. Hit 'control, alt, delete'. Computer froze at one of the first screens, 'All Rights Reserved'. Shut Power Bar, off/on, reset system. Shutter still closed. Switched to 'manaul', via controller box and was able to open shutter manually. Left system on 'automatic'. Shutter was not open. System was not operating when I departed the lab. Re: Brewer zs prism pointed up. sl prism pointed down. Did sl OK. zs prism pointed up. hg prism pointed down. Did hg OK 16:45-17:30 Drove Track Truck with plough back to station, to have it looked at. Tuesday, November 26, 1996 Weather (1600z): Clear; Wind NNW at 13 knts; Visibility 15+ mi; ice crystals; Temp -25 C. - clearing overnight, ice crystals. 13:24-14:04z POWER FAILURE. (not planned) 9:00-10:00 Gathered groceries and other supplies, while waiting for mechanics to finishing adjustments to Track Truck. Snow plough still holding up fine. Refuel Track Truck #1 (35 litres). 10:00-10:45 Drove to Astro via Track Truck (with plough). 10:45-13:15 Roof checks, temperature checks, instrument checks and log entries. Resolved usual problems associated with power failure. 4MI System had 'hung-up' and was displaying the following on screen: Had too many errors. I will shut donw, reboot and run again. Oh yeah, acq_get_int error c<"u 1/4. Switched power bar off/on to reset the system. MSP Corrected date and time. Musical alarm was going again when I restarted the program so I renamed the data file. ASC Cancelled power failure screen. The shutter was open and the system was operating. I viewed the tape. The shutter re-opened at 03:20z. However, the mirror was heavily frosted and obscured with snow. Brewer temp 17 C System had 'hung-up' and was displaying the following: Non-system disk or disk error replace and press any key when ready I hit, return, and the system rebooted OK, causing the Brewer to reset. Note: When I did the roof checks, the tracker Power wasn't on. 13:15-14:30 Re-stocked emergency food supply. Cleaned oven. 14:30-15:00 Checked email. 15:00-15:45 Updated weather log and general log. 15:45-16:30 Removed moon sheild and reattached using a piece of coated wire (instead of a bent paper clip). Collected garbage for removal. 16:30-17:00 Returned to weather station. Wednesday, November 27, 1996 Weather (2100z): Partly cloudy; Wind calm; Visibility 15+ mi; ice crystals; Temp -21 C. - mainly cloudy, snow, ice crystals and fog overnight. 9:00 Plane due to arrive at noon. Requested to meet incoming scientists. 11:30 Plane delayed until 2 or 3 pm. 14:00-14:30 Refueled 4x4 (75 lites). Refilled drinking water. 14:30-15:15 Met plane. Unloaded freight. 15:15-15:50 Drove to Astro, via 4x4. 15:50-16:30 Unloaded freight. Temperature checks. Tidied lab. 17:30-18:00 Drove to Astro, with Jim Whitway, Nagai, ?, and Wayne. 18:00-19:45 Roof checks and daily instrument checks. Continued trouble shooting problem with Brewer. It seems that 13 C (te) is the critical temperature below which the motor is unable to turn the gear that moves the prism. Cooled and warmed the Brewer three times and each time results were the same. Prism would move when the temperature was greater than 13 C but not when less than 13 C. When it was warming, if you applied light pressure on the gear, it would stop. Conclusion: There is a problem with the motor. 19:45-20:15 Returned to weather station. Thursday, November 28, 1996 Weather 1500z): Thin cloud; Wind N at 4 knts.; Visibility 15+ mi; Temp -25 C. - clearing overnight, ice crystals. 9:00-9:30 Obtained distilled water (for chillers for lasers) and drinking water. Checked oil on 4x4. 9:30-10:00 Drove to Astro via 4x4. Saw a group of 26 Arctic hare, approx. 500 meters south of Astro. 10:00-10:15 Passed on particulars of each experiment operating at Astro to A/OIC. (Apparently, the managers in Yellowknife are $1.2 million over budget for Eureka, and are trying to justify this.) 10:00-11:45 Roof checks, temperature checks, instrument checks and log entries. 4MI Time was +12 hours (therefore date was also incorrect). Reset. 11:45-12:00 Log. 12:00 ________________________________________________________________________ ************************************************************************ * Dave Harris, B.Sc., M.Sc. * * VP Academic MBA Students' Society * ************************************************************************ * E-mail: dave.harris@usask.ca * * * * Address: 36 Carleton Drive, Saskatoon, SK, S7H 3N6 * * Ph. 373-8038 * * MBA Executive Office, Room 151, College of Commerce * * Ph. 966-8405 * ************************************************************************
