Details:
2024 was a year of maximum solar activity in S hemisphere. 2025 may be the one in the N hemisphere. Since January the N hemisphere is active. Particularly, these days it is dominated by a huge group of 5 Active Regions. These include AR3981 (fast growing and delta since yesterday), AR3976 (gamma i.e. complex, delta a few days ago) and two other gamma. Particularly interesting is 3981 which already produced a dozen M flares. Lunt60 + Neptune-M. Very poor seeing due to strong wind.
