Dear Collaborators,

Solar activity has been at a high level since the last message. The largest event was an X1.3 flare at 19:01 UT yesterday, produced by NOAA 13777 (S09W26). This region remains classified as a beta-gamma-delta configuration but is becoming much more fragmented. Target region NOAA 13780 (S12E10) produced four ~M1 flares and three mid-level C-class flares in the period. 13780 retains a beta-gamma-delta/F-type configuration with a slight increase in sunspot area (now 1250 uh). This region now appears some signs of spot spilt in its leading portion. Today, the Major Flare Watch shall remain in effect with NOAA 13780 due to its overall size, magnetic complexity, and further evolution. M-class activity is expected, with a good chance of >M5 flares from various regions in the next 24-48 hours.

The position of NOAA 13780 on 9-Aug-2024 at 11:30 UT is:

S12E10 (-161",-297")
