The work is devoted to the analysis of the data of vertical sounding of the ionosphere from the Parus-A ionosondes during the partial solar eclipse of October 25, 2022. The solar eclipse covered Western Siberia, Europe, the Middle East, Central Asia, the eastern Arctic Ocean, the northeast Atlantic Ocean, and the northwest Indian Ocean. Several stations of vertical sounding of Roshydromet ionospheric network are located in the area covered by the eclipse: Kaliningrad, Troitsk, Rostov-on-Don, Elektrougli, Salekhard and Novosibirsk. Data from these ionosondes show that the solar eclipse causes a reaction of the ionosphere, in particular, a decrease in the critical frequencies of the reflecting layers and a decrease in the total electron content. The paper presents changes in the critical frequencies foE and foF2 and the minimum effective height of the F2 layer during the solar eclipse at some ionosondes caught in the shadow region. Interesting phenomena were found in the Siberian region, where the time of the solar eclipse coincided with the onset of twilight.
Keywords: ionosphere, vertical sounding, partial solar eclipse, ionospheric effects, ionospheric response
