Dear Collaborators,
Solar activity remains to be low since the last message. The largest
event was a C5.7 flare at 00:47 UT on 2/18 from NOAA 13990. The target
region, NOAA 13992 did not show further development in magnetic
configuration only having produced several low-to-mid C class flares
in the past 24 hours and now during the West limb passage.
NOAA 13998 is a new region that emerged a few days ago at the East of
NOAA 13996 and showing more than 20 low-to-mid C class flares since then.
This region is adding size and magnetic complexity and classified as a
beta-delta type. We will observe the center portion of NOAA 13998 as a
default target for the next 24 hours. Additional C class flares or larger
are
expected.
The position of the target in NOAA 13998 on 18-February-2025 at 16:30
UT is: S13E44 (-661", -149").

Dear Collaborators,
Solar activity continued to be at a low level, but slightly increased
since the last message. The largest event was an M1.0 flare at
15:07 UT today from NOAA 13992 approaching the West limb.
This region is experiencing new flux emergence at the Northwest
of the main positive sunspot and having produced 5 low-to-mid C
class flares in the past 24 hours.
We will observe the Northwest region of NOAA 13992 as the default
target for the next 24 hours. Additional C class flares are expected
with the chance of another M class event.
The position of the target in NOAA 13992 on 17-February-2025 at 16:30
UT is: S05W76 (936", -72").

Dear Collaborators,
Solar activity levels remain low. A small number of C-class flares were
produced, the largest being a C3.9 at 23:56 UT yesterday from NOAA 13996.
There has been minimal sunspot dynamism as most active regions on the disk
appear relatively stable. For now, NOAA 13990 will continue as the target
region. Further C-class activity is expected
The position of NOAA 13990 on 16-February-2025 at 12:30 UT is:
S09W61, (117", -36")

Dear Collaborators,
Solar activity has remained at a persistent low level. The largest flare of
the last 24 hours was an M1.8 from NOAA 13990 at 20:45 UT yesterday. NOAA
13992 has shown considerable decay since the last message, where NOAA 13990
has continued to produce a small number of flares. Additionally, a cluster
of flares was produced from currently unnumbered active regions close to
the eastern limb. The target region will switch to NOAA 13990 as this shows
more sign of continued flare production. This region is currently
classified as a beta-gamma region. C-class activity is expected in the next
24 hours with the additional chance for isolated low M-class flares.
The position of NOAA 13990 on 15-February-2025 at 16:30 UT is:
S10E03, (-50", -53")

Dear Collaborators,
Solar activity remains at a low level. The largest flare of the last 24
hours was an M1.3 from NOAA 13990 at 09:48 UT today. NOAA 13992 has shown a
slight increase in dynamic sunspot behaviour since the last message but
remains classified as a beta-gamma region. NOAA 13992 will continue as the
target region, however attention should also be paid to NOAA 13990. Further
C-class flares are anticipated with the chance for additional low M-class
activity.
The position of NOAA 13992 on 14-February-2025 at 12:30 UT is:
S06W33, (528", -4")

Dear Collaborators,
Solar activity persists at a low level. A small number of flares were
produced in the last 24 hours, the largest being an M1.1 at 11:05 UT today
from NOAA 13987 (in close proximity to NOAA 13992). NOAA 13990 and NOAA
13992 have been most active since the last message and both are classified
as beta-gamma regions. However, NOAA 13992 has shown much more sunspot
activity compared to NOAA 13990. Given this, NOAA 13992 will now be the new
target region. Additional C-class activity is expected with a slight chance
for an isolated low M-class flare in the next 24-48 hours.
The position of NOAA 13992 on 13-February-2025 at 12:30 UT is:
S06W18, (299", 7")

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:

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")
