Abstract

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-degrees 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 from the rocket in a northern location with respect to the rocket and was produced by electrons with a characteristic energy of 200-300 eV. The pulsatingaurora 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.
