Dear Collaborators,

Solar activity has continued at a moderate level since the last message. NOAA 13807 (S15W79) was the most flare-productive region on disk, being the source of eight mid-C-class flares and five low-M-class flares during the period, including the largest magnitude in the period - an M2.8 at 08:47 UT today. The Major Flare Watch shall switch to NOAA13807 before it completely rotates over the west limb. Yesterday's target NOAA 13813 (S23E28) remains classified as a beta-gamma region and produced two M1 flares and three mid-C-class flares in the period. Please note that NOAA 13806 (S12W30, beta-gamma-delta/E-type) and 13811 (S11E11, beta/D-type) each produced an M1.2 flare in the period. Further low-M- class activity is expected, with a chance of an isolated ≥M5 flare from various regions in the next 24-48 hours.

The position of NOAA 13807 on 5-Sep-2024 at 11:30 UT is:

S15W79 (902",-266")
