The results of investigations of ionosphere by means of the Kharkov incoherent scatter radar are presented. The measurements realized jointly with Massachusetts Institute of Technology (Haystack Observatory) and Cornell University (Arecibo Observatory) made it possible to reveal the longitudinal and latitudinal variations of topside hydrogen ion behavior. Ionosphere observations in Kharkov during the solar eclipse on August 11, 1999 first have been carried out up to 1500-km altitude. They have shown the significant changes in state of the F region and topside ionosphere including hydrogen ion concentration, plasma fluxes, that is the evidence of significant infringement of plasma exchange processes between ionosphere and protonosphere.
