Abstract: 
During the spe events, an experimentally observed increase in the electron concentration by more than 50–100% in the lower part of the midlatitude D region of the ionosphere (~ 70–80 km) for tens of minutes. The change in the ionization rate is estimated. On the basis of experimental data on changes in the electron concentration during periods of proton precipitation, the corresponding fluxes were estimated: 106–107 m – 2 s – 1, which are in good agreement with theoretical calculations.
