Dear Collaborators,

Solar activity has increased to a moderate-to-high level. The largest
event in the period was an M5.0 flare at 18:31 UT yesterday produced
by NOAA 13777 (S09W13, beta-gamma-delta/E-type). 13777 was
also the source of another three low M-class flares in the period.
Additionally, a South East limb region (S11E88) and NOAA 13781
(N13E29, beta-delta/D-type) also produced three low M-class flares.
Target region 13780 (S09E20) produced only six C-class flares in the
period, with a slight decrease in sunspot area (now 1110 uh) and an
increase in number of spots. 13780 has remained a beta-gamma-delta
configuration and high current helicity since the last message. 13780
continues to undergo a significant flux emergence across the entire
active region. Today, the Major Flare Watch shall remain in effect with
NOAA 13780, with a focus on its leading spots. Further M-class activity
is expected, with a good chance of >M5 flares from various regions in
the following 24-48 hours.

The position of NOAA 13780 on 8-Aug-2024 at 11:30 UT is:

S09E20 (-320",-244")
