Correlation between active regions’ spectra at high radio frequencies and solar flare occurrences

Abstract High radio frequencies observations with the Italian network of large single-dish radio telescopes resulted in $$\sim$$ 450 solar images between 2018 and 2023 in K-band frequency range (18–26 GHz). Solar radio mapping at these frequencies allows the probing of the Active Regions (ARs) chrom...
