We continued investigation of behavior of artificial satellites on orbit based on the complex comparison of the parameters of solar wind and geomagnetical activity with the changes of periods of orbital motion of the satellites. We used: 1) the periods of orbital motion of unсontrolled satellites from database of Ukrainian network of optical stations (УМОС) for 2012—2014 years; 2) the geomagnetic planetary indexes Kρ; 3) the energy spectra of protons and electrons obtained by satellites type GEOS for events during which the periods of orbital rotation of the satellites changed (all helio- and geo-data were taken from the database of Space Weather Prediction Center NOAA). We obtained, that energy spectra of streams of protons and electrons have no effect softening of the spectrum over time — to the time when a flare appears. It indicates the possibility of accumulation of particles over the active region (AR), causing further continuous energy discharge from the AR — a solar flare. We obtained relations between geomagnetic activity and solar wind speed at a given interplanetary magnetic field intensity for studied temporal changes of orbital motion periods of the artificial satellites of the Earth. The calculated correlation coefficients are of high values 0.93—0.96.
