Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA 14168 (N05W85) remained the most flare-productive region on the visible disk, producing over ten C-class flares and four low M-class flares, including the largest event of the period—an M2.3 flare at 14:57 UT yesterday, which exhibited prominent supra-arcade downflows (see SSW Latest https://www.lmsal.com/solarsoft/latest_events/#M2.3_AR_4168_N04W79_Supra_Arcade_Downflows_above_arcade_mid_to_late_gradual_phase Events entry https://www.lmsal.com/solarsoft/latest_events/#M2.3_AR_4168_N04W79_Supra_Arcade_Downflows_above_arcade_mid_to_late_gradual_phase). NOAA 14168 will remain the target region until it fully rotates over the west limb. C-class activity is expected, with a chance of additional low M-class events in the next 24 hours.
The position of NOAA 14168 on 11-Aug-2025 at 11:30 UT UT is:
N05W85 (939",72")
