Specific features of electron distributions at altitudes of 400 km.

New experimental data obtained on the orbital station 'MIR' in 1991 during solar maximum are discussed. Electron fluxes with Ee>75 keV were registered for three different directions as well as for electrons with Ee>300 and 600 keV. Spatial and time distributions of electron fluxes in the trapping region are presented. In the inner radiation belt an additional maximum is observed at L=1.25-1.35, and the fluxes in the 22-05h MLT interval are 2-3 orders of magnitude smaller, than during other local times. In this region a flattening of the electron spectrum is observed. The results obtained were compared with the AE-8 model.
