Influence of Solar Flares on VLF Radio Waves Propagation over JJI - Irkutsk Path

摘要

The article discusses the impact of solar flares on the amplitude of VLF radio waves propagating along the JJI -Irkutsk path. It is shown how the amplitude of the 22.2 kHz signal responds on perturbations in mid-latitude ionosphere during solar flares in 2017. Continuous measuring of parameters of the sounding signal was performed using the designed in the Irkutsk National Research Technical University VLF receiver. Analysis of the results showed linear dependence of the amplitude response and variations of X-ray intensity.
