Dear Collaborators,

The level of solar activity has increased due to an M4.5 flare at 
05:01 UT today from an unnumbered region near the northeast 
limb, which was mentioned yesterday. This region subsequently 
produced a C9.9 flare while its sunspot group was partially visible 
from Earth. Yesterday’s target has been numbered as NOAA 14196 
(S11E58, alpha/A-type) and NOAA 14197 (S17E60, beta/D-type). 
14197 was the source of an M1.0 at 09:04 UT today and some 
C-class flares. Today, the limb region should become the new target, 
considering a higher possibility of additional M-class flares occurring 
within the following 24-48 hours.

The approximate position of the target on 25-Aug-2025 at 11:30 UT is:

N04E89 (-950", 75")
