Notes on auroral activity at Eureka, Jan. 23, 1996, from Polar Camera

07:50	SA arcs visible at 557.7 nm toward E horizon (~50 deg z.a.)
07:58	SA arcs still there
08:02	arcs brighter, moving nearer zenith (Z)
08:12	single arc now, continuing to brighten
08:17	arc dims
08:30	arc brightens and appears first in N2+ emission (lower altitude)
08:39	arc brightens and moves nearer Z
08:43	arc in Z, now several quasiparallel arc fragments
08:52	arc now W of Z, fragmented as before
08:59	arc continues to drift W
09:11	arc has reintegrated and brightened
09:18	weakly visible in N2+ as well as [OI]
09:24	arc back in Z
09:38	arc in Z is stronger, finely rayed arc fragments in SW
09:43	Z arc quite bright in 557.7-nm, Z arc and rayed arcs visible in
	N2+ also, only Z arc apparent in 630.0-nm
09:51	Z arc and rayed arcs in SW have largely broken up
09:56	residue of Z arc brightest toward SW, perhaps drifting to NW
10:02	no arcs visible, increasing cloud apparent after this time
