Dear Collaborators,

Solar activity has reached a high level. The largest events
since the last message were two consecutive high-M flares
from two adjacent active regions, NOAA 13766 and 13764.
The two flares include an M7.9 at 01:39 UT and an M9.9 at
01:53 UT today eruptive with dimming and coronal waves.
13766 has developed to be a beta/D-type configuration and
13764 (S05E04) has been classified as an alpha/H-type
sunspot group, both of which are surrounded by the other
three active regions (NOAA 13763, 13765, and 13767).
At this time, we are implementing a Major Flare Watch on
NOAA 13766 (with NOAA 13764 in the field of view).
Yesterday’s target region NOAA 13762 (beta-gamma-delta/F-type,
S12W34) was a source of three low-to-mid M-class flares.
Further low-M activities are expected with a good chance
for another>M5 flare in the following 24-48 hours.

The position of NOAA 13766 at 07:30 UT on 28-Jul-2024 is:

S07E15 (-243", -202")
