Dear Collaborators,

Solar activity has dropped to a ~C2 level since the last message. The 
largest event was a partially occulted C2.9 flare at 09:24 UT today from 
an unnumbered region near the northeast limb (N09E89). This region 
also produced a C2.3 flare at 09:52 UT today. Its leading portion, which 
appears to show a high spot maturity, has already been partially visible. 
Today, the target shall switch to this limb region from NOAA 14188. 
14188 (Yesterday’s target) has been flare-quiet during this period. Note 
that a plage region (N13E26) also produced a C2.5 flare at 02:18 UT 
today. Additional C-class flares are expected in the next 24 hours.

The approximate position of the target on 20-Aug-2025 at 11:30 UT is:

N09E89 (-900", 150")
