Dear Collaborators,
Solar activity has decreased to an intermediate level since the last message. The target region, NOAA 14197, has been the most productive and produced multiple ~C2-C5 flares, including the largest being a C5.9 flare at 12:38 UT yesterday. This region has grown in the magnetic complexity to a beta-gamma-delta/E-type and the spot area to 740 μh. Today, the target shall remain with 14197. Further C-class activity is expected, with a chance for an isolated M-class flare in the next 24 hours.
The position of NOAA 14197 on 30-Aug-2025 at 11:30 UT is:
S18W04 (63", -405")
