S.M. Cherniakov et al. 5. Conclusion Results of observations of ionospheric effects of the March 20, 2015 total solar eclipse in the lower ionosphere of high latitudes according to the data of the partial reflections facility and the riometer located at the observatory “Tumanny” of the Polar Geophysical Institute (Murmansk region) are given. In general in the lower ionosphere during the eclipse maximum reduction of the electron concentration was noticeable, at the same time local increases in the electron concentration were noted. During the eclipse the changes of the electron concentration had wavy character. During the eclipse some waves transformed to two waves and united to one. Suppression of waves of the smaller periods in the field of reduction of the electron concentration at approach to the eclipse maximum was noted. Similar behavior has also cosmic noise absorption fixed by the riometer. These changes at the place of observations can be caused by passing of the acoustic-gravity wave generated by cooling the atmosphere during the supersonic passing of the lunar shadow across the Earth's surface, by changing of the electron concentration caused by the solar eclipse and vertical movements.
