An analysis of electron flux variations in the Earth’s radiation belts in May 2009 is performed on the basis of the data obtained from the satellite telescope of electrons and protons STEP-F as a part of scientific apparatus complex PHOTON aboard the spacecraft CORONAS-PHOTON. We investigate the temporal connection of particle intensity changes that were detected by the view cone of the device in the radiation belts at the bases of drift shells with various phases of the weak magnetic storm on 8 May, as well as with parameters of high speed solar wind streams. The empirical values of various energy electron life times in the basic inner and outer radiation belts are determined. The appearance frequency and dependence on the geomagnetic activity of the additional inner radiation belt appearing sporadically are studied.
