Dear Collaborators,
Solar activity has slightly decreased since the last message. The largest event during the period was a C4.9 flare at 10:30 UT today from the southwest limb (likely NOAA 14197, S18W91), which also produced several additional low C-class flares. The target region, NOAA 14207 (N29W10), has developed into a beta–gamma configuration and produced a C4.5 flare together with four additional low C-class flares in the period. This region continues to show new magnetic flux emergence in its intermediate and trailing portions. Today, NOAA 14207 will remain the default target. Further C-class activity is expected, with a chance of low M-class flares in the next 24–48 hours.
The position of NOAA 14207 on 6-Sep-2025 at 11:30 UT is:
N29W10 (145",355")
