The main feature of the last year of the development of the 25th solar cycle of the second cycle of the 2nd epoch of reduced solar activity is a sharp increase in spot-forming activity and, especially, the number of flare-active areas and, accordingly, an increase in the number of large solar flares, the most powerful in the growth branch of the current solar cycle. This placed it above the low solar cycle 24 and the transitional cycle 23 in terms of the number of significant flares during the corresponding period. In the maximum phase of the current solar cycle 25, the number of sympathetic flares of significant classes ( M1) increased noticeably, which made it possible to begin studying both such flares themselves and the active regions.
N.I. Lebedev (2025) studied this question.
