Dear Collaborators,

Solar activity has continued at a high level since the last message. The largest event was an M5.3 flare at 02:14 UT today, produced by the target region NOAA 13780 (S12W04). This region also produced another three ~M1 flares plus four mid-to-high C-class flares in the period. 13780 has been reclassified as a beta-gamma /F-type sunspot group with an area of 1280 MSH. We shall continue the Major Flare Watch on this region today. Additionally, NOAA 13777 (S09W40, beta-gamma/E-type) and NOAA 13784 (N15E54, beta/C-type) were also the sources of three M-class flares in the period, including an M4.6 flare from NOAA 13777 yesterday. Further M-class activity is expected, with a chance for additional >M5 flares from various regions in the next 24-48 hours.

The position of NOAA 13780 on 10-Aug-2024 at 11:30 UT is:

S12W04 (64",-299")
