Dear Collaborators,
Solar activity has returned to a low level since the last message.
The largest event was a C8.2 flare at 2:43 UT today(2/22) from an
unnumbered region newly emerged in the Northwest quadrant and is
approaching the limb. NOAA 13990, a sigmoid region produced 5 C
class events including a C8.0 at 16:01 UT on 2/21, but significantly
reduced in size and is undergoing a West limb passage.
Yesterday's target, now designated as NOAA 14000, produced 3 C
class flares with the largest being a C7.5 at 3:17 UT today. All of these
occurred from the area of following (negative) polarity. We will continue
to observe this region for another 24 hours, expecting additional C to
low-M class events.
The position of the target in NOAA 14000 on 22-February-2025 at
16:30 UT is: N17E01 (-17", 398").

Dear Collaborators,
Solar activity has increased to a low-to-medium level since the last
message. A new region emerged early 2/20 in the Northeast quadrant
grew rapidly and produced 2 M class flares (M3.4 at 12:05 UT and
M1.4 at 14:31 UT both on 2/21).
Yesterday's target NOAA 13996 has quieted since the last message with
no flare record, while NOAA 13998, the target of 2/19 increased in area
but dropped delta configuration (now classified as a beta-gamma type).
Today, we will observe the new target (yet unnumbered) in the
Northeast quadrant for the next 24 hours, expecting additional C to M
class activity.
The position of the target on 21-February-2025 at 16:30 UT is:
N16E10 (-174", 378").

Dear Collaborators,
Solar activity continues to be low since the last message. The largest
event was a C8.1 flare at 23:23 UT on 2/19 from NOAA 13990, a large
sigmoid region.
The target region, NOAA 13998 produced only a few low-C class activity
in the past 48 hours, while new flux is emerging from the Northeast of
the main negative sunspot. NOAA 13996 also has new flux emergence
at the center of the leading and following sunspots, showing several
low-to-mid C class activities in the past 24 hours. Several positive
satellite spots appeared in the Eastern vicinity of the negative leading
sunspot of NOAA 13996. Today, we will observe the leading sunspot of
NOAA 13996 as the default target. Additional C class flare or larger are
expected.
The position of the target in NOAA 13996 on 20-February-2025 at 16:30
UT is: S16W03 (57", -163").

Dear Collaborators,
Solar activity continues to be at a low level. The largest event in the
past 24 hours was a C4.2 flare at 10:41 UT on 2/19 from NOAA
13997 located near central meridian. NOAA 13990, a large sigmoid
region in the Western hemisphere produced 2 C3 class flares on 2/19.
The target region, NOAA 13998 has somewhat quieted, having produced
no flare events for more than 36 hours. However, it maintains magnetic
configuration of a beta-delta type and showing new flux emergence
with sunspot motion. We will continue to observe NOAA 13998 at the
region of flux emergence for the next 24 hours. Several C class events
are expected.
The position of the target in NOAA 13998 on 19-February-2025 at 16:30
UT is: S12E31 (-493", -116").

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")
