SINOPSIS

Using a partial reflection technique, there were experimentally investigated changes in the electron density, N, in the ionospheric D-region at the time of solar proton events, spe. Increasing by more than 50-100% in the electron density in the lower D-region of the ionosphere (~70-80 km) was observed during several tens of minutes. Estimations of changes in the ionization rate were made. On the basis of the experimental data on electron density changes over the proton precipitation periods, corresponding flows were estimated, being ~106 -107m-2sec-1.
