Dear Collaborators,
Solar activity continues to be at a low-to-moderate level. The largest
event in the past 24 hours was a C9.3 flare at 23:12 UT on 2/27 from
NOAA 13996 behind the Southeast limb. The target region NOAA
13998 produced 2 C class events and undergoing the limb passage
today.
NOAA 14006 is a region classified as a beta-gamma type (D-type),
currently transiting the North central meridian. Although no flare
activity is recorded in the past few days, its leading (positive)
area made of multiple sunspots is showing relative movements and
actively producing jets best seen in EUV 304A line. Today we will
observe the leading sunspots of NOAA 14006 as a default target,
expecting a few C class events.
The position of the target in NOAA 14006 on 28-February-2025 at
16:30 UT is: N19W05 (82", 430").

MM#009 Default Target
Solar activity has been at a low-to-moderate level. The largest
event in the past 24 hours was a C7.5 flare from NOAA 13996
located in the Southeast of the target region NOAA 13998. This
region was activated since late yesterday has been producing more
than ten C class flares, but now undergoing the limb passage.
From the target region NOAA 13998, only C4.5 event was recorded
in the past 24 hours, but frequent brightening is occurring
associated with the flares from NOAA 13998. We will continues to
observe NOAA 13998 at the region of leading (negative) sunspot
for the next 24 hours, expecting additional C class events.
The position of the target in NOAA 13998 on 27-February-2025 at
16:30 UT is: S12W78 (929", -180").

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The largest event in the past 24 hours was a C5.7 flare from NOAA
14007 in the Southeast quadrant. NOAA 14006 in the Northeast
quadrant significantly increased its area and magnetic complexity
yesterday but showing no flare record during the recent 24 hours.
The target region, NOAA 13998 has slightly decreased its area and
number of sunspots, but continues to interact with the trailing area
of NOAA 13996, having produced two low-to-mid C class flares.
We will continue to observe NOAA 13998 at the region of leading
(negative) sunspot, expecting additional C to low-M class events.
The position of the target in NOAA 13998 on 26-February-2025 at
16:30 UT is: S12W65 (861", -165").

Dear Collaborators,
Solar activity continues to be at a medium level. The largest event
in the past 24 hours was an M3.9 flare from behind the Southwest
limb, probably due to the eruption of the filament located between
NOAA 13990 and 13991 followed by a bright post-flare loop arcade.
The target region, NOAA 13998 has significantly increased its size
(from 290 to 430 millionths) and continues to show a sign of flux
emergence. This region produced 2 M class flares (M1.3 at 2:25 UT
and M3.6 at 11:20 UT both on 2/25) and the latter event occurred
between the leading negative sunspots and NOAA 13996's following
positive sunspots. Today we will continues to observe NOAA 13998
on the area of leading (negative) sunspot, expecting additional C to
M class events.
The position of the target in NOAA 13998 on 25-February-2025 at
16:30 UT is: S13W53 (755", -148").

Dear Collaborators,
Solar activity continues to be at a medium level. An X2.0 flare was
produced from the West limb region, NOAA 14001 at 19:22 UT on 2/23,
followed by an M1.3 at 01:33 UT today. However, this region is now
located far behind the limb, and thus we do not select as the target
of the observations for the next 24 hours.
The second largest event was from an M3.3 event from NOAA 14000
at 06:53 UT today, but no other flare record so far. On the other hand,
yesterday's target, NOAA 13998 continues to show flare activity with
the largest being an M1.0 event at 16:18 UT on 2/23. Although this
region does not have a delta configuration anymore, its size is still
growing and showing dynamic sunspot motions. We will continues to
observe the center portion of NOAA 13998 for the next 24 hours.
Additional C to low-M class flares are expected.
The position of the target in NOAA 13998 on 24-February-2025 at
16:30 UT is: S12W35 (550", -112").

Dear Colleagues,
Solar activity has increased to a medium level since the last message.
The largest event was an M4.9 event at 2:00 UT today(2/23) from NOAA
14001 approaching the West limb. This region produced 2 C8 class
flares yesterday and another M class flare today (M1.6 at 11:47 UT)
but will complete the limb passage today.
The target region, NOAA 14000 developed mix polarity in the following
sunspots and now classified as a beta-gamma-delta type. However, it
is kind of dormant with respect to flare activity with no flare record
in the past 24 hours. On the other hand, NOAA 13998 underwent
significant flux emergence with its size increased from 220 to 280
millionths during the past 24 hours. This region is producing more
than 10 C class flares and an M1.0 at 09:54 UT today, showing rapid
sunspot movements. Today we will observe NOAA 13998 at the region of
new sunspots for the next 24 hours.
The position of the target in NOAA 13998 on 23-February-2025 at 16:30 UT is:
S12W23 , ( 371", -102" ).

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").
