Abstract
The results of experiments on radio sounding of near the Sun plasma by the signals of the Mars Express Mars satellite are presented. In the region of heliocentric distances of the proximate point of the line of sight of 8–13 solar radii, frequency fluctuations of transmission radio signals were measured. During the experiments sharp increases in the variance of frequency fluctuations were recorded on both the eastern and western limbs. In measurements near the Earth’s orbit on the Wind spacecraft in adjacent periods with a delay of 5–17 days, increases in the proton concentration and magnetic field strength were recorded at 7–15 times the background values. A comparison between the data related to the inner and near-Earth solar wind indicates that the observed disturbances are associated with the same region of the solar corona rotating with the Sun
