On the programs of monitoring studies of space weather based on radio astronomical and magnetometric observations

A comprehensive monitoring program has revealed significant variability in the fluxes of extragalactic radio sources, such as supernova remnants and radio galaxies, linked to space weather effects. Conducted since 1987 using advanced radio telescopes (URAN-4, RT-32, RT-16, LOFAR) and magnetometers across Ukraine, Latvia, Finland, and other regions, this study highlights the impact of solar activity on terrestrial ionospheric conditions. Observations during the 2025 solar eclipses further elucidated local space weather manifestations along the UNESCO-listed Struve Geodetic Arc. The research, supported by the Latvian Council of Science, underscores the importance of multi-national collaboration in characterizing extreme space weather events and their ionospheric effects.
