Abstract
The paper presents the analysis of experimental data on electron fluxes with energies 10Â keV-10Â MeV. Data were obtained during 1978-2005 years in different space experiments (COSMOS-900, MIR Space Station, ACTIVE, SAMPEX, CORONAS-I, CORONAS-F, NOAA POES-17, TATYANA and others). Two areas of electron flux enhancements are studied in the paper: the near-equatorial (LÂ <Â 1.2) zone and the middle-latitude (1.2Â <Â LÂ <Â 1.9) zone. It is shown that electron flux enhancements are regularly registered at LÂ <Â 2 and the observed formations have some typical features. Electron peaks at LÂ <Â 1.2 appear sporadically while peaks at 1.2Â <Â LÂ <Â 1.9 are observed regularly. The approximations of spectra by several functions including kappa-function are presented.
