  The work concerns a problem of electron-induced contaminant at relatively low
latitudes to high-energy astrophysical measurements on board the low-orbiting
satellites. We show the results of a statistical analysis of the energetic
electron enhancements in energy range 30-300 keV observed by a fleet of
NOAA/POES low-orbiting satellites over the time period from 1999 to 2012. We
demonstrate geographical distributions of great and moderate long-lasting
enhancements caused by different type of the solar wind drivers.
