In the time period (from 01.01.2007 till 31.12.2007), relating to the end phase of the 24th solar activity cycle decline (the minimum solar activity was observed in 2009), satellites orbiting outside the Earth’s magnetosphere provided information that variations have been registered of solar wind plasma speed, as well as of density, temperature and intensity of interplanetary magnetic field, and of galactic cosmic rays particle fluxes intensity. In the Earth’s outer radiation belt, the geostationary satellites registered intensity variations of electron fluxes with the electrons energy
of several tens of keV to several MeV. The ground stations observed variations of geomagnetic activity indexes. The authors have showed that the maximum variation intensity of interplanetary medium parameters, geomagnetic activity indexes and ionizing radiation fluxes in the Earth’s outer radiation belt was observed at the speed of Sun rotation. The authors also have demonstrated that close to the Sun activity minimum, the intensity of particle flux (with the particles energy of 30 to 100 MeV) of galactic cosmic rays within the high speed recurrent stream of solar plasma was lower than in the surrounding space environment. The turbulence spectrum intensity of the interplanetary magnetic field within the high speed recurrent plasma stream has been demonstrated to be 10 times more than in the surrounding space environment.
