Dear Collaborators,

Solar activity has reached a moderate level due to an eruptive 
M1.1 flare at 03:51 UT today from NOAA 14188. This region 
has also produced two flares (a C2.2 and a B9.2) since the 
last message. It was classified as an alpha/H-type sunspot 
group as it transited onto the disk. Today the target shall switch 
to NOAA 14188 from NOAA 14180. Yesterday’s target, NOAA 
14180, merely produced a C1.2 flare at 03:40 UT today. Further 
C-class activity is expected within the coming 24 hours.

The position of NOAA 14188 on 19-Aug-2025 at 11:30 UT is:

S09E65 (-849", -194")
