Influence of local time and power of solar x-ray flashes of M and X classes on the variation of frequency of first mode of Schumann resonance

The paper presents the results of an analysis of the frequency variations of the first mode of the of Schumann resonator in the geophysical observatory Mikhnevo of the Institute of Geospheres Dynamics of Russian Academy of Science (IDG RAS) during solar X-ray flares of the M and X classes in 2011 - 2017. It is shown that the frequency variation depends not only on the flash class, but also on the magnetic field component and local time. It is suggested that this is due to the geometry of the path from the African Thunderstorm Activity Center.
