Dear Collaborators,

Solar activity has slightly decreased since the last message. 
The largest event during the period was a C3.6 flare at 04:51 
UT today from the target region NOAA 14172 (N08W91), which 
also produced over ten additional low C-class flares in the 
period. NOAA 14172 shall remain the target region today before 
it rotates over the west limb. Further C-class activity is expected 
within the next 24 hours.

The position of NOAA 14172 on 17-Aug-2025 at 11:30 UT is:

N08W91 (937",132")
