Dear Collaborators,
Solar activity was at a moderate level. The largest event
over the past 24 hours was an M1.8 flare at 06:31 UT on
November 7 produced by the target region NOAA 14274.
14274 was also the source of more than ten C-class flares.
It remains a beta-gamma-delta/E-type configuration. Today
we will continue the Major Flare Watch on this region for a
further 24 hours. Please note that another region NOAA 14276
(S17E53, beta-gamma/D-type) as mentioned yesterday was
also the source of a few C-class flares. Low M-class activity
is expected with some chance of a major flare of above M5.0
in the following 1-2 days.
The position of NOAA 14274 on November 8 at 00:30 UT is:
N24E12 (-184", 339")

Dear Collaborators,
Solar activity decreased in the past 24 hours. The largest event
over the period was an M1.1 flare at 04:17 UT on November 6,
produced by a southeast limb region, now numbered as NOAA
14276 (S17E67). 14276 also produced about six C-class flares
including a C9.4 at 19:48 UT. It was designated as a beta-gamma/
D-type region. The target region NOAA 14274 only produced seven
C-class flares, with the largest one being a C5.3. 14274 remains
a beta-gamma-delta/E-type configuration but increases in the
sunspot area. Today we will continue the Major Flare Watch campaign
on this region. A major flare of above M5.0 is still possible in the
next 1-2 days.
The position of NOAA 14274 on November 7 at 00:30 UT is:
N24E26 (-389", 342")

Dear Collaborators,
Solar activity remains at a high level. The target region
NOAA 14274 produced two major flares, an M8.6 at 21:52 UT
and an M7.5 at 10:36 UT on November 5. This region also
produced seven C-class flares during the period. It remains
a beta-gamma-delta/E-type configuration. Additional major
flares are expected in the next few days.
The position of NOAA 14274 on November 6 at 00:30 UT is:

Dear Collaborators,
Solar activity continues at a high level. The target region
NOAA 14274 produced the largest event, an X1.8 flare
at 17:15 UT on November 4. It also produced about nine
C-class flares during the period. Please note that a south-
east limb region produced an occulted X1.2 flare at 21:45 UT.
14274 has been designated as a beta-gamma-delta/E-type
configuration. Today we will continue the Major Flare Watch
campaign on NOAA 14274. Additional major (>M5.0) flares
are expected in the next 24-48 hours.
The position of NOAA 14274 on November 4 at 20:30 UT is:

Dear Collaborators,
Solar activity has been at a high level since the last message.
The largest event of the period was an M5.0 flare at 09:38 UT
on November 3, produced by the northeast limb region, now
numbered as NOAA 14274. This region also produced five low
M-class (including an M3.5 at 01:31 UT, still underway) and
more than ten C-class flares. At this time, we are implementing
the Major Flare Watch campaign on NOAA 14274, which has
been designated as a beta-gamma/E-type configuration. Additional
major flare of above M5.0 will be likely in the next few days.
The position of NOAA 14274 on November 4 at 00:30 UT is:
N24E63 (-800", 380")

Dear Collaborators,
The level of solar activity has increased slightly. An unnumbered
region (N04E89) behind the limb produced the largest event, a
partially occulted M1.1 flare at 00:13 UT today. To the north of this
region, the target region has been numbered as NOAA 14272 and
has been classified as an alpha/H-type sunspot group since the
last message. It produced four low-C flares, including a C4.5 at
10:56 UT today. Today, the target shall remain at 14272, because
of its high productivity. Further C-class activity is expected in the
coming 24 hours.
The position of NOAA 14272 on 2-Nov-2025 at 12:30 UT is:
N22E69 (-838", 337")

Dear Collaborators,
Solar activity has increased to an intermediate level, due to
a C7.1 flare at 19:37 UT yesterday, produced by the target
region. This region (unnumbered yet) was also the source of
four low-C flares and became the most productive region.
Today, the target shall continue as this limb region. More
low-C activity is expected, with a chance for another high-C
flare in the following 24 hours.
The approximate position of the target on 1-Nov-2025 at 12:30 UT is:
N23E88 (-878", 415")

Dear Collaborators,
The level of solar activity remains low since the last message.
The largest event was a partially occulted C1.8 flare at 01:44 UT
today from an unnumbered region behind the northeast limb.
This region also produced two B6 flares. This eastern limb
region becomes the new target. Yesterday’s target has almost
rotated out of Earth-view. Additional low-C flares are very likely
in the following 24 hours.
The approximate position of the target on 31-Oct-2025 at 08:30 UT is:
N24E88 (-880", 400")

Dear Collaborators,
Solar activity remains at a low level. The largest event since
the last message was a C1.4 flare at 11:59 UT today, produced
by a spotless region near the southwest limb. This region also
produced a B6.4 flare. Today, the target will switch to this limb
region, due to its return to C-class flaring. Yesterday’s target,
NOAA 14266 (beta/C-type, N17W46), became quiescent during
the period. Further B-class activity is expected, with a chance
for another low-C flare in the next 24 hours.
The approximate position of the target on 30-Oct-2025 at 12:30 UT is:
S09W88 (950", -150")

Dear Collaborators,
Solar activity has continued at a low level. The target NOAA
14266 produced a B9.1 flare at 05:05 UT today. This region
has grown in its magnetic complexity to a beta/C-type, exhibiting
the emergence of new spots in its following portion. Today, the
target shall remain with NOAA 14266. In addition, NOAA 14267
(beta/C-type, N04W04) also produced a C1.6 flare at 16:17 UT
yesterday, while a region behind the southwest limb was the
source of four high-B flares. Further B-class activity is expected,
with a chance for another low-C flare in the following 24 hours.
The position of NOAA 14266 on 29-Oct-2025 at 12:30 UT is:
N16W32 (493", 202")
