Photometric images of 130.4-, 337.1-, 391.4-, and 557.7-nm auroral airglow emissions are presented for November 16, 1980, and December 9, 1981. Unique observations and new data reduction techniques allow 360¿ imaging of the local auroral emissions on both days and a view of spatial and temporal variability. The 1980 aurorae, one nonpulsating and one pulsating, are located in the morning sector. We find that the 1980 diffuse, nonpulsating aurora was located 75 km in a western location and was produced by electrons with a characteristic energy of 2--3 keV. Both the near (northern) and far (western) aurorae had motion and size characteristics consistent with northeasterly drift rates of 200--500 m s-1 and 30--50 km in size, respectively. The 1981 flight observed a stable arc in the evening sector. The arc was produced by electrons with a characteristic energy of 1--3 keV and had a probable 1/e width of approximately 75 km. For both flights, the 557.7/391.4 and 337.1/391.4 ratios were approximately constant. ¿ American Geophysical Union 1993
