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.
