Dear Collaborators,
Solar activity has increased to a high level since the last message.
The largest event was an X1.6 flare at 11:03 UT, happening just now,
produced by the target region NOAA 13697 (S19W91). This region
also produced another four M-class flares (M1.0, M3.3, M2.3, and
M5.3) and several C-class flares during the period. Today we will
continue the Major Flare Watch campaign on NOAA 13697 before
it completely rotates over the west limb. Further C- and M-class
activity is expected,…

The position of NOAA 13697 on 10-Jun-2024 at 11:30 UT is:
S19W91 (892",-307")

Dear Collaborators,
Solar activity has decreased to a moderate level since the last message.
Target region NOAA 13697 remains a beta-gamma-delta configuration
and produced the vast majority of flare activity during the period, being
the source of more than ten C-class flares and the largest magnitude
flare in the period - an M1.7 on 9-Jun-2024 at 06:49 UT. Additionally,
NOAA 13709 (S10E51, beta/C-type) and NOAA 13703 (S08W61, beta-
gamma/D-type) each produced an ~M1.0 flare in the period. …
[View More]Today we
will continue the Major Flare Watch campaign on NOAA 13697 as it
rotates to the west limb. If possible, please also include the nearby region
13703 in the field of view. Further C- and M-class activity is expected,
with a chance for an isolated >M5 flare.

Dear Collaborators,
Solar activity has increased to a high level since the last message.
The largest event in the period was an M9.8 flare at 01:23 UT today
from the target region NOAA 13697. This region remains classified
as a beta-gamma-delta configuration and also produced another
three low M-class flares plus nine C-class flares during the period.
Today we continue the Major Flare Watch on this region due to the
continued flux emergence in its intermediate portion. Please note
that the …
[View More]southeast limb region, mentioned in the two previous messages,
has been numbered as NOAA 13709 (S10E67, beta/C-type) and
has produced four ~M1.0 flares during the period. Further M-class
flares are expected, with a chance of an X-class flare in the next
24–48 hours.

Dear Collaborators,
Solar activity is at a moderate level. The target region NOAA 13697
has produced an M1.3 flare and nine mid-to-high C-class flares in
the last 24 hours. 13697 remains a beta-gamma-delta configuration
and continues to undergo flux emergence in its trailing portion. The
largest magnitude flare in the period was an M4.1 at 08:52 UT today
from the southeast limb region (S10E89) mentioned in the previous
message. This limb region also produced another two C5.8 flares
during the …
[View More]period. However, the Major Flare Watch will remain with
NOAA 13697 due to its magnetic complexity, high current helicity,
and past flaring history.

Dear Collaborators,
Solar activity has slightly increased since the last message.
The largest event during the period was an M6.1 flare at
14:50 UT today, produced by the target region NOAA 13697.
13697 remains classified as a beta-gamma-delta configuration
and was also the source of six C-class flares, including two
~C8 flares. The Major Flare Watch will continue with NOAA
13697 as the target region, due to its magnetic complexity
and continued flux emergence. Please note that a southeast

Additional >M5 activity is possible in the next 24-48 hours.

Dear Collaborators,
Solar activity continues at a moderate-to-low level. The largest event
during the period was an M3.5 flare at 08:32 UT today produced by
the target region NOAA 13697. This region was also the source of
another M2.6 flare and two low C-class flares. 13697 retains a
beta-gamma-delta configuration, but decreases in the sunspot area.
The Major Flare Watch will be extended for a further 24 hours with
NOAA 13697 as the target region, due to its magnetic complexity
and continued …

expected, with a slight chance for an isolated >M5 flare.

Dear Collaborators,
Solar activity was at a moderate-to-low level. The largest event during
the period was an M2.4 flare at 06:09 UT today produced by the target
region NOAA 13697. This region also produced another M1.7 flare and
a few C-class flares (including three C8 flares). NOAA 13697 retains a
beta-gamma-delta configuration, with some new emerging sunspots in
its trailing portion. Considering that its current helicity remains at a high
level, we will continue the Major Flare Watch on …

Dear Collaborators,
Solar activity has slightly diminished since the last message. The target
region NOAA 13697 remains classified as a beta-gamma-delta configuration,
with an increase in sunspot area and number of spots. This region continued
as the most flare-productive region on disk, being the source of four low
M-class flares plus more than ten C-class flares, while the largest magnitude
flare was an M4.8 at 13:58 UT today from NOAA 13695 (N27W42, beta/C-type).
The Major Flare Watch will …
[View More]continue with NOAA 13697 as the target region
due to its magnetic complexity, ongoing flux emergence, and prior
flaring history.
Additional M-class flares are expected from these two regions, with a chance
for major (>M5) flares in the next 24-48 hours.

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13697 produced over 15 flares, including an X1.0 at
18:24 UT yesterday. The Major Flare Watch will continue as this region
shows signs of dynamic sunspot behaviour and complexity. Additional
M-class activity is expected, with a chance for an isolated >M5 event
in the next 24 hours.

Dear Collaborators,
Solar activity has partially increased since the last message. NOAA
13697 produced two X-class flares, the largest being an X1.4 at 08:26
UT today. This region remains classified as a beta-gamma-delta and
shows signs of significant flux. The Major Flare Watch will continue
with NOAA 13697 as the target region. Additional >M5 activity is
possible in the next 24-48 hours.
