Abstract
EXOS-C observed precipitation of protons of energy 0.64 – 35 MeV and electrons of energy 0.19 -3.2 MeV parallel to the geomagnetic equator in the low-latitude region, mid-latitude region, and the auroral region in order of increasing intensities during the time interval (1984-86). The detector efficiency shows that the locally mirroring particles (pitch angle 90 degrees) outnumber those of other pitch angles. In the low-latitude region, the electron peak flux lies in the L- range of 2-2.2, and the proton peak flux between L=1.8 to 2.0. In the mid-latitude region, proton peaks lies between l = 2.2 to 2.4. The peak value of the particle population lies between 650 and 700 km. The particle population shows no longitude dependence within 140o to 360o. There is a shortage of data points in the other longitude range. In certain passes of the satellite, electron counting rates outnumber the proton counting rates and in some other passes the opposite effect occurs. Either altitude variation or a temporal variation or both may play a role for this opposing effect. No local time variation was found.
