Behavior of High-Energy Magnetospheric Electrons in Solar Cycles 22–24

The behavior of high-energy magnetospheric electrons with energies of >2 MeV in geostationary orbit during solar cycles 22–24 is considered. It is shown that the most increases in electrons occurs during the declining phase of solar activity, when a greater number of geoeffective coronal holes are observed. The 2003–2015 data show there is generally a correspondence between the behavior of the number of increases in electrons and the area of geoeffective coronal holes.
