ESTIMATION OF THE PARAMETERS OF THE LOWER IONOSPHERE DURING X-RAY FLARES ON THE PROPAGATION PATHS OF VLF SIGNALS RECEIVED AT THE MIKHNEVO AND UL’YANOVKA OBSERVATORIES

Abstract
The paper presents a comparative analysis of the reconstructed ionospheric parameters based on the data of receiving VLF signals at the Mikhnevo and Ul’yanovka observatories during the solar flare on 07/03/2021. It is shown that the developed method for reconstructing ionospheric parameters is applicable to paths of various lengths. A further development of the technique is proposed, which could ensure the reconstruction of the ionospheric parameters on a single-frequency path from measurements at two points.
