High-Energy Magnetospheric Electrons and Different Types of Disturbances of the Interplanetary Medium

The effects interplanetary disturbances induced by coronal plasma ejections and the high-velocity solar wind from coronal holes have on high-energy ( E > 2 MeV) magnetospheric electrons are investigated. Experimental data collected over 30 years of observations (1986–2017) are analyzed. Coronal plasma ejections and high-velocity outflows from coronal holes are shown to have different effects on the behavior of high-energy electrons: the latter create stronger electron fluxes at geostationary orbits than the former.
