POLAR AURORAS AND AIRGLOW DURING THE NOVEMBER 1993 NATIONAL SPACE WEATHER
INITIATIVE EVENT

D. P. Steele, University of Saskatchewan

A sensitive multiwavelength all-sky imager operated at Eureka, NWT (80 N,
273 E; 88.7 PACE GMLat) during the November 1993 National Space Weather
Initiative Event.  Polar auroral and airglow emissions were imaged at 
several wavelengths including [OI] 630 nm and 558 nm.  Polar patches were
observed from 2200 UT (local twilight) on Nov. 3 through 1330 UT (local 
dawn) on Nov. 4, and again from 2200 UT on Nov. 4 through 0100 UT on 
Nov. 5 when the last patches were observed.  These observations will be 
presented in the form of a video sequence, together with the time history 
of the convection velocity at the center of th northern polar cap, inferred
from the patch motions.
