Dear Collaborators,
Solar activity has returned to a high level since the last message. The largest event was an M9.4 flare at 19:25 UT on July 30, produced by the southeast region NOAA 13772 (S25E52, beta/D-type). This region also produced an M6.0 flare peaking at 13:05 UT, happening just now. Yesterday's target region, NOAA 13764 (S03W40, beta/D-type), was the source of an M1.9 flare and two high C-class flares. Today, the Major Flare Watch will switch to 13772. Additionally, some other active regions located on the southern visible solar disk were the source of M-class flares, including an unnumbered region near the east limb (S07E88, M4.8) and some western active regions: NOAA 13768 (S16W64, beta-gamma-delta/E-type, M7.7), 13773 (S06W50, beta /C-type, M2.0), and 13766 (S07W32, beta-gamma/E-type, M1.5). Further M-class activity is expected with a good chance for additional
M5 flares from various regions in the next 24-48 hours.
The position of NOAA 13772 on 31-Jul-2024 at 11:30 UT is:
S25E52 (-676",-451")
