Information × Registration Number 0207U008668, 0107U003108 , R & D reports Title Observations of the solar wind parameters by IPS technique. popup.stage_title Head Falkovich Igor Savelievich, Registration Date 19-12-2007 Organization Institute of Radio Astronomy National Academy of Sciences of Ukraine popup.description2 The series of IPS observations has been carried out with the largest in the world radio telescopes UTR-2 and URAN-2. The analysis of the experimental data allows the mean velocity and the dispersion of the solar wind velocity to be estimated. It was found that the solar wind usually has a stream structure, i.e. there exist several streams with different parameters along the line of sight. It is shown that the common analysis of spectra and dispersion dependencies of phase velocity allows locations of streams with different velocities to be obtained. In most cases, the times of CMEs arrival, geomagnetic storm beginning, estimated by radio observations with the UTR-2 radio telescope and ones obtained by other methods are in good agreement. The correlation between S4 index of the ionospheric scintillations and the solar wind flow of electrons with energy <0,6MeV (El-1) has been also found.
