Abstract

Measurements of relativistic electrons (500 keV to 12 MeV) within the drift loss cone during geomagnetic storms in the spring of 1994, obtained with MKL instrument aboard the low-altitude (∼500 km) polar-orbiting satellite, CORONAS-I, are reviewed. CORONAS-I satellite observed two more pronounced electron enhancements during the period studied (March-April 1994). Time profile of Dst index indicates that these events occurred after magnetic storms on March 6-8, 1994 (Dst = -109 nT) and April 2-4, 1994 (Dst = -111 nT). Both time and L shell variations of the precipitating electron fluxes over the wide L shell range of 1-9 are presented and discussed. On the average, these fluxes had a maximum value at L = 3.8-4.6 observed during the storm recovery phases.
