Dear Collaborators,
Solar activity continues at a low level. NOAA 13981 has now rotated fully
out of view - this region produced the largest flare of the last 24 hours
before rotating behind the limb; a partially occulted C7.7 at 13:28 UT
yesterday. In the southeastern quadrant, NOAA 13990 has developed into a
beta-gamma region, though it appears relatively stable. The target region
will switch to NOAA 13990. Further C-class activity is expected in the next
24 hours.
The position of NOAA 13990 on 12-February-2025 at 12:30 UT is:
S09E47, (-703", -74")

Dear Collaborators,
Solar activity has continued at a low level. NOAA 13981 was the site of
several partially occulted flares, the largest being an M1.6 at 05:22 UT
today. NOAA 13981 is almost fully beyond the northwest limb. New active
regions appear to be rotating onto the disk from the northeast and
southeast limb, although they have shown little activity. At present the
target region shall remain around NOAA 13981 and the northwestern limb in
an effort to catch further partially occulted events. Additional C-class
flares are expected.
The approximate position of NOAA 13981 on 11-February-2025 at 12:30 UT is:
N07W91, (964", 115")

Dear Collaborators,
Solar activity has continued at a low level. A small number of flares were
produced, the largest being an M1.0 from NOAA 13981 at 00:30 UT today. NOAA
13981 continues to traverse the northwest limb but remains in view.
Additional active regions from beyond the eastern limb appear to be
emerging and may move onto the disk in the coming days. NOAA 13981 will
continue as the target region while it remains in view. Additional C-class
activity is expected with a chance for a partially occulted event in the
next 24 hours.
The position of NOAA 13981 on 10-February-2025 at 12:30 UT is:
N07W76, (936", 144")

Dear Collaborators,
Solar activity has reduced since the last message. The largest flares of
the last 24 hours were both C4.5 flares, from NOAA 13977 and NOAA 13981 at
00:49 UT and 02:33 UT today, respectively. NOAA 13981 has begun its
progression over the northwest limb, the region still shows signs of
emerging flux in short wavelengths, but may have diminished in area. At
this time, we are ending the Major Flare Watch but persisting with NOAA
13981 as the target region. Further C-class activity is likely in the next
24 hours with a slight chance for an isolated M-class event in the next 24
hours.
The position of NOAA 13981 on 09-February-2025 at 12:30 UT is:
N08W63, (859", 184")

Dear Collaborators,
Solar activity remains at a low-intermediate level. A number of flares were
produced over the last 24 hours, the largest being an M2.1 from NOAA 13981
at 08:57 UT today. NOAA 13981 is now classified as a beta-delta region as
it begins its approach of the northwestern limb. This region shall continue
to be monitored. The Major Flare Watch will remain active for now, with
NOAA 13981 as the target region. Further C-class activity is expected with
a chance for additional M-class activity in the next 24 hours.
The position of NOAA 13981 on 08-February-2025 at 12:30 UT is:
N08W49, (728", 206")

Dear Collaborators,
Solar activity is at a low-intermediate level and several flares were
produced in the last 24 hours. NOAA 13981 was the site of another M7.6
flare at 08:59 UT today. The emerging flux from this region remains high
and the dynamic sunspot behaviour continues. The Major Flare Watch will
remain active with NOAA 13981 as the target region. Additional C- and
M-class activity is likely with a chance for further >M5.0 flares in the
next 24 hours.
The position of NOAA 13981 on 07-February-2025 at 12:30 UT is:
N08W38, (594", 220")

Dear Collaborators,
Solar activity remains at a low-intermediate level. A number of flares were
produced in the last 24 hours, the largest being an M7.6 at 10:47 UT today
from NOAA 13981. This region has been persistently productive and has grown
to 430 μh, while retaining its beta-gamma-delta configuration. The Major
Flare Watch will continue with NOAA 13981 as the target region. Further C-
and M-class activity is expected in the next 24 hours, with a chance for an
additional isolated >M5.0 event.
The position of NOAA 13981 on 06-February-2025 at 12:30 UT is:
N07W25, (409", 216")

Dear Collaborators,
Solar activity is at a low-intermediate level. Several flares were produced
in the last 24 hours. The largest being an M2.7 from NOAA 13977 at 07:44 UT
today. NOAA 13981 continues to grow in sunspot area and has strong emerging
flux. However, its level of sunspot dynamism appears to be reducing. As
NOAA 13981 continues to produce flares and remains complex, the Major Flare
Watch will be extended for a further 24 hours. Additional C-class activity
is likely with a slight chance for isolated >M5.0 events in the next 24-48
hours.
The position of NOAA 13981 on 05-February-2025 at 12:30 UT is:

Dear Collaborators,
Solar activity has continued at an intermediate level since the last
message. Numerous flares were produced from NOAA 13981 including several
M-class flares, the largest being an M4.7 at 11:09 UT today. NOAA 13981
continues to show significant flux and high flare production rate. The
Major Flare Watch will remain active with NOAA 13981 as the target region.
Further M-class activity is likely with a chance for additional >M5.0
flares in the next 24 hours.
The position of NOAA 13981 on 04-February-2025 at 12:30 UT is:

Dear Collaborators,
Solar activity has increased since the last message. A substantial number
of flares were produced in the last 24 hours, the largest being an M8.8 at
03:52 UT today from NOAA 13981. NOAA 13981 has shown rapid development in
complexity and flux. This region is currently classified as a
beta-gamma-delta and has produced over 25 flares since the last message,
three of which were >M5.0. The Major Flare Watch will continue and the
target region will switch to NOAA 13981. Further M-class activity is
possible with a chance for additional >M5.0 flares in the next 24 hours.
The position of NOAA 13981 on 03-February-2025 at 12:30 UT is:
