Dear Collaborators,

Solar activity has grown to a high level. The largest event 
since the last message was an M8.2 flare at 23:31 UT 
yesterday from the target region NOAA 14100. It retained a 
beta-gamma/E-type sunspot group and increased in sunspot 
area to 440 μh. The target shall remain with NOAA 14100, 
although we are issuing a Major Flare Watch alert at this time 
due to the increased possibility of another >M5 flare within the 
next 24-48 hours.

The position of NOAA 14100 on 31-May-2025 at 07:30 UT is:

N08E10 (-163", 144")
