Abstract: | The relation of the maximal daily average values of the relativistic electron fluxes with an energy higher than 2 MeV, obtained
from the measurements on GOES geostationary satellites, during the recovery phase of magnetic storms to the solar wind parameters
and magnetospheric activity indices has been considered. The parameters of Pc5 and Pi1 geomagnetic pulsations and the relativistic
electron fluxes during the prestorm period and the main phase of magnetic storms have been used together with the traditional
indices of geomagnetic activity (A
E, K
p, D
st). A simple model for predicting relativistic electron fluxes has been proposed for the first three days of the magnetic storm
recovery phase. The predicted fluxes of the outer radiation belt relativistic electrons well correlate with the observed values
(R ∼ 0.8–0.9). |
