Abstract

The VLF signals from DHO and JXN registering in Yakutsk. During the solar eclipse on June 10, 2021 the maximum VLF amplitudes increased by 1.62 dB (11:39:18 UTC) and 1.4 dB (11:26:42 UTC) respectively. The relative changes of the ionizing radiation flux during an eclipse is characterized by the ratio of the areas of the open solar disk part to the total solar disk S(Φ)/S₀. Along the DHO – Yakutsk and JXN – Yakutsk propagation paths the minimum average values S(Φ)/S₀ are 0.532 (11:39:18 UTC) and 0.411 (11:33:00 UTC) respectively. The time of radio paths overlapping by the lunar shadow does not contradict the time interval of VLF amplitude variations registering in Yakutsk during the solar eclipse.
