Data on the long-term dependences of the electromagnetic manifestations of lightning discharges and their behavior during geophysical disturbances were obtained based on systematic observations of ELF bursts at the Akademik Vernadsky station and in the Northern Hemisphere. The results of data processing of ELF radiation registered at the UAS in 2023-2024 were analyzed. Seasonal variations in the intensities and peak frequencies of Schumann resonances, as well as their changes depending on the 11-year cycles of solar activity were obtained. Based on the results of the two-position location (Antarctica - Arctic) of powerful ELF bursts, daily and seasonal patterns of the behavior of thunderstorm centers were obtained. Recommendations were formulated for optimizing the operating modes and data processing algorithms of the new broadband magnetometer LEMI-120 installed at the UAS during seasonal work in 2024. The ELF interference at the location of the receiving system on the UAS was analyzed. Proposals for the better location of the receiving ELF system outside Galindez Island were formulated.
