More than 500 energetic Electron Precipitation Events were observed in the Earth's Northern and Southern polar atmosphere during a long-term cosmic ray balloon experiment. The results of analysis of these events allow to show (1) distribution of occurrence rate of EPEs within solar activity cycle, (2) semiannual variation in the EPE occurrence, (3) interplanetary and geomagnetic conditions related to the EPEs in the atmosphere.

Abstract. Specific type of energetic electron precipitation accompanied by a sharp increase in trapped energetic electron flux are found in the data obtained from low-altitude NOAA satellites. These strongly localized variations of the trapped and precipitated energetic electron flux have been observed in the evening sector near the plasmapause during recovery phase of magnetic storms. Statistical characteristics of these structures as well as the results of comparison with proton precipitation are described. We demonstrate the spatial coincidence of localized electron precipitation with cold plasma gradient and whistler wave intensification measured on board the DE-1 and Aureol-3 satellites. A simultaneous localized sharp increase in both trapped and precipitating electron flux could be a result of significant pitch-angle isotropization of drifting electrons due to their interaction via cyclotron instability with the region of sharp increase in background plasma density.Key words.
