Dear Collaborators,
Solar activity has reached a moderate level. The largest event since the last message was an M3.4 flare at 05:56 UT produced by the target region NOAA 14100. This region also produced five ~C1 plus two high-B flares, and was the most productive in the period. It retained a beta-gamma/E-type sunspot group and emerged new positive magnetic fluxes in its leading portion. Further C-class activity is expected, with a chance for another low-M flare in the next 24-hour period.
The position of NOAA 14100 on 30-May-2025 at 11:30 UT is:
N08E21 (-337", 145")
