Аннотация:The spectrum of phenomena produced by geomagnetic storms in the near
Earth’s environment is gradually widened as observational data increase.
One of them is significant enhancements of energetic electrons (>10 keV)
revealed recently in the forbidden zone below the radiation belt. A
comprehensive analysis of the forbidden electron enhancements during
major and recurrent magnetic storms in solar cycles 23 and 24 was
conducted on the base of experimental data acquired from low-orbiting
satellites from 1998 to 2014. A possible mechanism of the phenomenon
is discussed. Knowledge of where and when such environmental events
will occur can be used for both space physics and applied researches. We
focus on the following radiation aspects of the electron enhancement
problem with a short review for each item: 1) ionization impact of 10-30
keV electrons in the ionosphere; 2) X-ray and gamma-ray contaminations
by 100-300 keV electrons to astrophysical observation on board loworbiting
satellites; 3) possible effects of energetic electrons in satellite
anomalies attributed to low-orbit radiation environment.
