Dear Collaborators,
NOAA 13380 continues to dominate solar activity, producing several
C-class flares and five M1 flares since the last message. The region
retains its beta-delta configuration as it approaches the southwest
limb and is showing dynamic behavior around its leader spot. We shall
continue with the Major Flare Watch in effect with NOAA 13380 as the
target region. Sustained intermediate level activity likely with
chance for an >M5 flare over the next 24 hours.
The position of …

Dear Collaborators,
Solar activity has increased significantly since the last message due
to NOAA 13380 doubling in size and increasing in complexity. It is now
classified as a beta-delta region and has produced six M-class flares
today including an M3.6 at 06:28 UT. At this time we are implementing
a Major Flare Watch campaign with NOAA 13380 as the new target region
due to the increased likelihood of an M5 flare or greater over the
next 24 hours.

Dear Collaborators,
Solar activity continues at a moderate level with events from both
NOAA 13380 and NOAA 13390 since the last message. Despite its small
sunspot area NOAA 13390 was the source of an M1.7 flare at 08:42 UT
today. It retains its beta/C-type configuration and shall continue as
the target region with further C- and low M-level activity possible
over the next 24 hours.

Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13390
has been re-classified as a beta/C-type sunspot group with having
rotated further on disk. NOAA 13380 (a beta/D-type) was the source
of an M1.4 flare on 29-Jul-2023 at 16:11 UT, but the target region
NOAA 13390 produced a double-peaked M-class event where both X-ray
peaks reached M1.8 (each flare starting on 30-Jul-2023 at 08:01 UT
and 08:18 UT). C-class activity is expected over the following 24
hours, with …

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13388
has been stable since the last message, remaining classified as
a beta/C-type sunspot group. Old region NOAA 13376 produced the
largest magnitude flare in the period from beyond the North West
limb (an M4.1 on 28-Jul-2023 at 15:39 UT), but is now completely
out of view. Newly numbered region NOAA 13390 (an alpha/H-type)
has already produced four mid-to-high C-class events, with the

Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA
13376 has now rotated over the North West limb, with only some of
its highest-lying loops still visible. This region was the source
of multiple mid-to-high C-class flares since the last message. The
target will however switch to NOAA 13388 that rotated on disk over
the South East limb in the last 48 hours. NOAA 13388 is classified
as only a beta/C-type sunspot group, but was the source of an M1.7
flare on 28-…

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13376
remains designated as a beta/D-type sunspot group, but has now
rotated up to the North West limb so classification is uncertain.
NOAA 13376 continued to be the most flare-productive region in
the period with being the source of multiple C-class flares and
two M-class events, which included the largest magnitude flare
(an M2.0 on 26-Jul-2023 at 15:50 UT and an M1.9 on 27-Jul-2023
at 09:44 UT). Continued C-class …

Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13376
has continued to emerge new magnetic flux since the last message,
but remains classified as a beta/D-type sunspot group because its
proximity to the North West limb prevents accurate classification.
NOAA 13380 (beta/C-type) produced an M-class flare in the period
(an M1.6 on on 25-Jul-2023 at 21:08 UT), while target region NOAA
13376 produced two M-class events including the largest magnitude
flare (an M1.2 …
[View More]and M4.6 on 26-Jul-2023 at 04:21 UT and 10:17 UT,

activity as NOAA 13376 rotates up to the limb.

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region NOAA 13380
was stable in terms of sunspot area since the last message and has been
confirmed as a beta/C-type sunspot group now that it is fully on disk.
This region was the source of low C-class activity in the period while
NOAA 13376 produced a C-class flare and the largest magnitude flare, an

episode of flux emergence and consolidation over …

evolve from an alpha/H-type sunspot group into a compact beta/D-type,

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13373 decayed
slightly in terms of sunspot area over the past 24 hours, but it has
remained a beta/E-type sunspot group classification. Both NOAA 13372
(a beta/C-type group) and NOAA 13373 produced C-class flares in the
period. However, the new region rotating over the South East limb -
now designated as NOAA 13380 - has again produced C-class activity.
This new region (NOAA 13380) has not completely rotated its …
[View More]trailing
spots onto the visible disk, but it appears to have at least a beta
magnetic classification and its main leading spot has a well-formed
mature penumbra (so either a C- or D-type Zurich classification).

expected over the following 24-hour period, with a chance for a low
M-class flare.
