Abstract : Measurements of the spatial distributions and temporal variations of the extraterrestrial 'ring current' proton intensities near the magnetic equator during selected phases of two moderate magnetic storms provide direct evidence of asymmetric injection of these proton intensities deep into the outer radiation zone during the early development of the latter magnetic storm. Inspection of these low-energy protons (5 < E < 50 keV) into the evening-midnight quadrant of the outer radiation zone to L-shells approximately = 3.5 was accompanied by a substantial polar magnetic substorm observed during similar local times. However, no increases of proton intensities at levels above those typical of the 'quiescent ring current' centered at L approximately = 6.5 were yet observed several hours later near local noon. Several implications concerning the magnetic storm are discussed. (Author)
