[en] Investigations of variations of fast electrons in the external radiation belt of the Earth were conducted. Integral fluxes of particles penetrating through a layer of Al 3 gxcm^-2 thick were measured with the aid of a gas-descharge counter from July, 1968 to September, 1970 on several ''Molniya-1'' satellites. Using data obtained for the same trajectory for external and internal radiation belt particles penetrating beyond 0.7 gxcm^-2 shielding and data on protons from solar flares, it is possible to single out variations of the intensity of electrons at the energy of Esub(e) > 5 MeV in the external radiation belt. Detected were three large increases in intensities of the electrons during the period considered (6 to 7 times as high as compared to the initial level) with subsequent drop according to the exponential law with a characteristic time of 15 days. Observed are relatively fast (during the time of about a day) variations of electron fluxes against a background of a slow drop
