Dear Collaborators,
Solar activity continues at a low level. A number of low C-class flares
were produced in the last 24 hours, the largest being an occulted C1.4 from
an unnumbered active region beyond the southeastern limb at 05:28 UT today.
The target region is now numbered as NOAA 14288. This region is currently
classified as an alpha-type region, however this is expected to change as
the region moves further onto the disk. NOAA 14288 will continue as the
target region, with further C-class activity expected over the next 24
hours.
The position of NOAA 14288 on 21-November-2025 at 12:30 UT
N16E68, (-867", 287")

Dear Collaborators,
Solar activity remains at a low level. Several flares were produced since
the last message, the largest being a C2.3 at 09:59 UT today from a
currently unnumbered active region in the southeastern quadrant of the
disk. The unnumbered active region beyond the northeast limb continues to
be productive, meanwhile NOAA 14284 has shown no significant developments.
The target region will switch to the northeastern limb in proximity to the
productive active region. Further occulted C-class activity is anticipated.

Dear Collaborators,
Solar activity persists at a low level. Several flares were produced over
the last 24 hours, the largest being an occulted C9.9 at 09:29 UT today
from a currently unnumbered active region over the northeastern limb. NOAA
14284 produced no further flares since the last message and appears stable.
However, for now, NOAA 14284 will remain the target region, but attention
should also be paid to the northeastern limb surrounding the currently
occulted active region as it begins its transit onto the solar disk.
Further C-class activity is expected in the next 24 hours.
The position of NOAA 14284 on 19-November-2025 at 12:30 UT is
S07W39, (608", -148")

Dear Collaborators,
Solar activity is at a low level. NOAA 14284 produced multiple flares since
the last message, the largest being a C5.4 at 16:49 UT yesterday. NOAA
14284 remains classified as a beta-type region and remains compact, however
it has shown signs of growth over the last 24 hours. NOAA 14284 will remain
the target region. Further C-class activity is expected in the next 24
hours.
The position of NOAA 14284 on 18-November-2025 at 12:30 UT is
S07W26, (423", -155")

Dear Collaborators,
Solar activity has further reduced since the last message. Several flares
were produced over the last 24 hours, the largest being a C7.5 from NOAA
14284 at 01:23 UT today. The previous target region, NOAA 14274, has now
progressed fully beyond the solar limb. Newly numbered active region NOAA
14284 has produced the majority of flares since the last message. This
region is currently classified as a beta-type region with a chance of
development over the coming 24 hours. At this time we are ending the MFW
and the target region will switch to NOAA 14284. Further C-class activity
is expected, with a very slight chance for an isolated low M-class event.
The position of NOAA 14284 on 17-November-2025 at 12:30 UT is
S07W12, (201", -160")

Dear Collaborators,
Solar activity has remained at a moderate level since the last
message. The target region NOAA 14274 produced the largest
event, being an M3.1 at 07:49 UT yesterday, and numerous
C-class flares as it rotates beyond the northwest limb. Today,
the Major Flare Watch will remain with the looptop of 14274 for
maybe the final 24 hours. Low-M activity is likely, with a chance
for an isolated >M5 flare in the following 24 hours.
The position of NOAA 14274 on 17-Nov-2025 at 00:30 UT is:
N25W91 (878", 410")

Dear Collaborators,
Solar activity has dropped to a moderate level over the past
24 hours. The target region NOAA 14274 produced 16 flares,
with the largest ones being two M1.3 flares at 20:04 UT and
21:22 UT yesterday, respectively. It retains a beta-gamma-delta/E-type
sunspot group. Today, the Major Flare Watch shall continue on
14274, due to its prior >M5 flaring history and current high
productivity. Additional low-M flares are possible, with a chance
for an isolated >M5 flare in the coming days.
The position of NOAA 14274 on 15-Nov-2025 at 12:30 UT is:

Dear Collaborators,
Solar activity has returned to a high level, due to an X4.0 flare
at 07:44 UT today from the target region NOAA 14274. This
region was also the source of an M1.8 flare and several low-C
flares as it rotates towards the northwest limb. Today the Major
Flare Watch shall remain with 14274, because of the increased
probability of another above M5 flare within the following 24-48
hours.
The position of NOAA 14274 on 14-Nov-2025 at 12:30 UT is:
N24W71 (838", 379")

Dear Collaborators,
Solar activity has grown to an intermediate level in the past
24 hours. The largest event was a C6.1 flare at 02:43 UT
today from the target region NOAA 14274. This region also
produced six low-C flares, with a beta-gamma-delta/E-type
sunspot group. Today, the Major Flare Watch will continue as
14274 for a further day, due to its high magnetic complexity
and large spot area of 1000μh. Note that NOAA 14276
(S17W22, beta-gamma/C-type) was also the source of five
low-C flares in the period. C-class activity is expected, with
an >M5 flare possible in the coming 1-2 days.

Dear Collaborators,
Solar activity has dropped to a low level since the last message.
The target region NOAA 14274 was the source of seven low-C
flares, with the largest being a C4.2 flare at 16:51 UT yesterday.
This region retains a beta-gamma-delta/E-type magnetic
configuration and has increased in spot area to 1100 μh. Today,
the Major Flare Watch will remain on NOAA 14274. More C-class
flares are expected, with a chance for an isolated >M5 flare in the
coming days.
