Summary

Air Force satellite P78-1 carries several experiments investigating solar activity and charged particle and electromagnetic radiation measurements. One of these experiments consists of a set of electrostatic analyzers to collect electrons from 50 eV to 20 KeV in 16 channels. The sensors are exactly the same as the SSJ/3 sensor on DMSP satellites. Since the satellite is spinning at a rate of 11 + or- 1 rpm, complete pitch angle information is obtained in about 5.45 sec by each of the two sensors which are 90 degrees apart. Three passes are reported, showing where each pass is during a different intensity of magnetic activity. Oval boundaries, spectral shapes, and total energy fluxes are determined and compared to the results of others. Results from the two sensors are compared to each other.
