Dear Collaborators,

Solar activity has been at a low level since the last message. 
Most low-C flares came from NOAAs 14099 and 14100. NOAA 
14099 (beta/D-type, S13E34) was the source of five ~C1-C2 flares. 
NOAA 14100 produced three ones, with the largest being a C2.1 
at 01:18 UT today. This region has emerged new sunspots and 
has been classified as a beta/E-type magnetic configuration. Today 
we shall end the Major Flare Watch campaign, and the default 
target shall switch to NOAA 14100, due to its higher magnetic 
complexity. Yesterday’s target region has already rotated beyond 
the west limb. More C-class activity is expected in the next 24 hours.

The position of NOAA 14100 on 28-May-2025 at 11:30 UT is:

N08E48 (-698", 144")
