Dear Collaborators,
Solar activity has dropped to a moderate level. The target region NOAA 14098 produced the largest flare in the period - an M2.9 at 12:50 UT yesterday. It was also the source of three low-to-high C-class flares. 14098 retained a beta-gamma/D-type sunspot group but showed signs of decay in its following portion. Today, the Major Flare Watch will be extended for the last 24 hours with NOAA 14098. Note that NOAA 14100 (beta/D-type, N07E59) also produced an M1.4 at 13:27 UT yesterday, plus several C-class flares as it rotated on disk. Additional low-M activity is likely, with a slight chance for an isolated >M5 flare in the coming 24 hours.
The position of NOAA 14098 on 27-May-2025 at 11:30 UT is:
S04W77 (920", -61")
