The general concept of the near-Earth radiation asserts that fluxes of energetic electrons in the equatorial ionosphere and outside SAA are stably tenuous and negligible due to permanent effective scattering and losing energy in interaction with atmospheric neutrals. In literature, this region is called a forbidden zone because it locates below the inner allowed Störmer zone or inner radiation belt. Radiation monitoring by a fleet of the NOAA satellites in low Earth orbit have revealed significant enhancements of energetic electrons in the forbidden zone. Statistical studies showed that enhancements of forbidden energetic electrons (FEE) relate to substorm activity. Knowledge of where and when such environmental events will occur can be used in both space physics and applied researches. Ionospheric and space weather effects of the FEE enhancements are considered.
