Vertical sounding of the ionosphere before, during, and some time after the eclipse was at 1- and 5-minute intervals. Scintillations of radio signals from artificial satellites were registered at frequencies of 150 MHz (3-channel spaced reception), 40 MHz and 180 MHz (single-channel reception). Slant sounding was along the path Moscow-Kiev in the frequency range from 3.5 to 27.5 MHz. A very strong magnetic storm was registered at the Kiev Magnetic Observatory before the eclipse; this storm which lasted 150 hours was preceded by considerable helioactivity. The solar flares and magnetic storm caused an ionospheric storm with very great delta f(0)F2 deviations. During the eclipse, the usual effect was not registered due to strong helio-geomagnetic activity. The E-region anomalies were observed: a local ionization cloud was formed with a very narrow range of electron concentration, decreasing from the low-frequency end. The F1 layer was formed an hour earlier. The effective recombination coefficient obtained during the period of the eclipse agrees with data from rocket experiments.
