ENERGETIC ELECTRON INJECTIONS TO THE INNER MAGNETOSPHERE DURING MAGNETIC STORMS AND MAGNETOSPHERIC SUBSTORMS

Radial injections of the energetic electron to the inner magnetosphere during magnetic storms are studied using data from the SERVIS-1 low altitude satellite. Fast radial injections with time scale less than 1-2 hours were found during the main storm phase in 0.3-3.4 MeV electron energy channels. Coincidence with an active phase of the magnetospheric substorms was found after inspection of the auroral zone magnetometer records. It seems that fast electron injectionare the result of the electron radial injection caused by the induced electric field of the magnetic field dipolarization during substorm activations. As a «seed» particles freshly accelerated auroral electrons and «old» radiation belt electrons may be regarded.
