Space–Time Structure of Energetic Electron Precipitations according to the Data of Balloon Observations and Polar Satellite Measurements on February 1–6, 2015

The results of an analysis of the space–time characteristics and dynamics of precipitations of magnetospheric electrons with energies in the range from 0.1 to 0.7 MeV are presented. According to the data on electron fluxes measured by vertical and horizontal detectors on the Meteor M2 , POES-18 , and POES-19 satellites, particle precipitations were identified that corresponded to an event recorded during the balloon experiment carried out by the Lebedev Physical Institute on February 2, 2015. Precipitations were found at L -shells from 4 to 8 over the wide MLT range. During the event under study the regions in the near-equatorial magnetosphere have been determined, where the mechanisms are predominantly active, which are responsible for the scattering of electrons and their invasion into the Earth’s atmosphere.
