The electron formation under the radiation belts at L-shells 1.2-1.9
Abstract
We continue to analyze the distribution of electron fluxes with energy 30-500 keV under the radiation belts at low and middle latitudes (L=1.2-1.9) using experimental data obtained onboard ACTIVE satellite. The special attention is given to altitudinal distribution of electron fluxes and detailed analysis of these electron formations. We observe three main constant existing regions of electron flux registration under the radiation belts. There are: magneto conjugated to SAA region (in the north hemisphere), local zone of low intense electron flux accumulation to the west of SAA, and extensive region in the north hemisphere to the east. The analyze of experimental data obtained from ACTIVE satellite (orbit height 500-2500 km) shows that electron fluxes are registered in wide altitude range up to 1100 km. It is shown that these formations have complicated initial structure with to regions of flux maximums at L=1.3 and L=1.6-1.8. We compare the particle data with low frequency (LF) data (ARIEL-4 satellite) and high frequency (HF) data (CORONAS-I satellite). Also we discuss the possible mechanisms of the appearance of these formations under the radiation belts.
