Dear Collaborators,

Solar activity has diminished since the last message. Yesterday's target NOAA 13768 produced an M1.5 flare and six mid-to-high C-class flares in the period, but is now completely out of view. The largest event in the period was an M1.9 flare at 07:11 UT today, produced by NOAA 13765 (S11W68, beta-gamma-delta/E-type). 13765 was also the source of two mid-to-high C-class flares in the period. Today, the Major Flare Watch shall switch to NOAA 13765 due to its magnetic complexity, continued flux emergence, and the complexity of the magnetic field connection between it and the nearby active regions. Please note that a northeastern limb region (N12E88) and some other active regions (NOAA 13775, 13766, 13777 and 13770) were also the source of M-class flares in the period. Further M-class activity is expected, with a chance for >M5 flares from various regions in the next 24-48 hours.

The position of NOAA 13765 on 3-Aug-2024 at 11:30 UT is:

S11W68 (861",-215")
