Satellite Observations of Extreme Ultraviolet Radiation.

Abstract

The first Extreme UltraViolet (EUV) spectrometer (ECOM-721) was flown on the DOD satellite P78-1. The instrument collected a large amount of high quality data on the Earth's atmosphere, ionosphere and magnetosphere. It is still the only such experiment performed from a satellite. Because the instrument was on a spinning satellite, in a noon-midnight polar orbit at 600km altitude, it obtained a huge amount of unique data of geophysical interest. A substantial number of important geophysical observations were made, including the first spectrum of the polar cusp under sunlight, the first spectrum of the EUV nightglow emissions, the first spectrum of the tropical airglow in the EUV, the first spectrum of the nightside aurora below 800A, the detection of dielectronic recombination emissions in the atmosphere, and the first spectrum of the polar cap emissions in the EUV.
