Dear Collaborators,

Solar activity has been at a moderate level since the last message. Target region NOAA 13780 (S13E37) produced only two mid-level C-class flares during the period. However, 13780 retains its beta- gamma-delta/F-type configuration with an increasing sunspot area (now 1220 uh) and number of spots. Considering that 13780 remains a high current helicity and continues to undergo a significant flux emergence in its leading portion, today we will continue the Major Flare Watch on this region. Please note that the largest event in the period was an M4.5 flare at 13:30 UT today produced by NOAA 13774 (S07W17, beta-gamma/E-type). 13774 was also the source of an M1.8 flare and three mid-to-high C-class flares in the period. Additionally, NOAA 13781 (N13E46, beta-gamma/D-type) produced an M1.1 flare as well. M-class activities are expected with a chance of >M5 flares from various regions in the next 24-48 hours.

The position of NOAA 13780 on 7-Aug-2024 at 11:30 UT is:

S13E37 (-556",-292")
