Some features of electron diurnal variation at geostationary orbit

The paper studies the diurnal variation of electron fluxes at the geostationary orbit. Data were being acquired from a middle-energy-range (E: ∼80–1000 keV) electron semiconductor spectrometer on the Gorizont satellite from July, 1991 to April, 1992. During as long as two months (July–September) we...

Description
Summary:The paper studies the diurnal variation of electron fluxes at the geostationary orbit. Data were being acquired from a middle-energy-range (E: ∼80–1000 keV) electron semiconductor spectrometer on the Gorizont satellite from July, 1991 to April, 1992. During as long as two months (July–September) we were observing appearance of different energy electron flux intensity maxima in the diurnal distribution in dusk and dawn sectors which may be explained by features of the particle drift in the strong dawn-dusk asymmetric magnetosphere and by passing through a quasi-trapped region.
