Аннотация:The results of spectral observations of solar UV radiation in the range NUV297-330nmon the summer solstice of 2019 at the NIS "Ice Base"Cape Baranova" (arch. Severnaya Zemlya) and the village of Barentsburg (arch. Svalbard). According to the values of the spectraldensity Int 297–330 nm, the main groups of fluctuations with periods of 3–7 min, 20–30 mincorresponding to the harmonics of solar oscillations 2 MHz–4 MHz were identified. According to seasonal observations at the NIS "Ice Base"Cape Baranova" from 01.03.2019 to31.08.2019, the relationship of the average daily values of Int 297–330 nm with the corresponding values of the absolute magnitude of the Earth's magnetic field module (r ~ -0.6) wasestablished. The revealed dependence characterizes the NUV297–330 nm radiation as an indicator of the level of magnetic disturbance.
