Dear Collaborators,
Solar activity has remained low since the last message. The largest
event during the period was a C2.0 flare at 22:23 UT yesterday from
the target region NOAA 14381 (N08W05, beta/D-type). 14381 also
produced three additional low C-class flares in the period. Today, we
will continue to observe NOAA 14381 as the default target. Additional
low C-class activity is expected over the next 24 hours.
The position of NOAA 14381 on 6-March-2026 at 12:30 UT is:
N08W05, (83",254")

Dear Collaborators,
Solar activity has decreased slightly since the last message. The largest
event during the period was a C1.9 flare at 07:03 UT today from a newly
emerged region NOAA 14383 (N15W62). Yesterday’s target NOAA 14384
(N09E33, beta/E-type) produced only several high B-class flares during
the period. Today, we will switch the target to NOAA 14381 (N08E09, beta/
C-type), as it is undergoing significant flux emergence in its trailing
portion.
C-class activity is expected over the next 24 hours.
The position of NOAA 14381 on 5-March-2026 at 12:30 UT is
N08E09, (-150",253")

Dear Collaborators,
Solar activity remains low. The largest event since the last message
was a C4.1 flare at 02:57 UT today, produced by the target region
NOAA 14384. This region was also the source of another seven low
C-class flares during the period. Today, NOAA 14384 will remain the
target region. Further C-class activity is expected over the next 24
hours.
The position of NOAA 14384 on 4-March-2026 at 12:30 UT is
N10E46, (-687",250")

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The largest event in the period was a C3.0 flare at 00:17 UT today,
produced by NOAA 14381. The target region NOAA 14384 produced
four low C-class flares during the period, the largest of which was a
C1.6 flare. Today, NOAA 14384 remains the target region due to
ongoing magnetic flux emergence and signs of partial sunspot
coalescence. Further C-class activity is expected over the next 24
hours.
The position of NOAA 14384 on 3-March-2026 at 12:30 UT is
N10E60, (-826",227")

Dear Collaborators,
Solar activity has decreased slightly since the last message.
The largest event during the period was a C4.5 flare at 04:29
UT today from NOAA 14384 (N10E70), a northeastern limb
region mentioned previously. This region also produced ten
additional low C-class flares during the period. Yesterday’s
target NOAA 14381 (N08E50) produced four low C-class
flares during the period, with the largest being a C2.7 flare.
Today, we will switch the target to NOAA 14384 due to its
flare history and ongoing flux emergence in its trailing portion.
Further C-class activity is expected over the next 24 hours.
The position of NOAA 14384 on 2-March-2026 at 08:30 UT is
N10E70, (-896",208")

Dear Collaborators,
Solar activity has slightly increased since the last message.
The largest event in the last 24 hours was a C6.1 flare at 01:55 UT
today(3/1) from the boundary area between NOAA 14380 and 14379.
Both regions appear to be in the decaying process.
The region having been behind the limb in the East of NOAA 14381,
the supposed source of several C class flares since yesterday, has
come into our view. This unnumbered region produced several C class
flares in the past 24 hours, with the largest being a C4.7 at 21:18
UT yesterday. Yesterday's target, NOAA 14381 produced 6 C class
flares in the period, including a C5.2 at 6:07 UT and a C5.9 at
7:30 UT today.
Today, we will continue to observe NOAA 14381 at the central region
with mixed polarity between its leading and following sunspots.
Additional C class events are expected.
The position of the target in NOAA 14381 on 1-March-2026 at 17:00 UT
is: N08E59 (-828", 196").

Dear Collaborators,
Solar activity remains low since the last message. The largest event
in the last 24 hours was a C6.5 flare at 02:56 UT today (2/28) from
the West side of the leading sunspot of NOAA 14380, but activity
from this region has reduced in the latest 12 hours.
The sunspot that rotated from the East limb (~N08 deg) yesterday
was registered as NOAA 14381. This region is reported as the source
of several low-C class flares, but some of them appear to come from
the area behind the limb rather than from the sunspot on the solar disk.
Today, we will switch the target to NOAA 14381 because of the recent
flare history. We will observe the East of the main sunspot so that
its Eastern extension is covered. Additional C class events are
expected.
The position of the target in NOAA 14381 on 28-February-2026 at
17:00 UT is: N08E76 (-931", 169").

Dear Collaborators,
Solar activity has slightly increased from the last message.
The largest event in the last 24 hours was a C6.3 flare at 18:56 UT
yesterday (2/26) from the East limb (at ~5 deg. North), where a
medium-sized sunspot is coming into our view. This region is also
the source of a few low-C class flares including a C3.5 at 12:47 UT
today.
Yesterday's target, the Southeastern portion of NOAA 14379 has been
assigned a new number, NOAA 14380 and has begun to progress onto
the solar disk. This region consists of larger sunspots than NOAA
14379 with more magnetic complexity, having produced 6 low-C class
flares since the last message.
In the next 24 hours, we will continue to observe NOAA 14380, due
to the continuing flare activity for a couple of days. Additional C class
flares are expected from its trailing (positive polarity) sunspot.
The position of the target in NOAA 14380 on 27-February-2026 at
17:00 UT is: S19E68 (-848", -282").

Dear Collaborators,
Solar activity has reduced to a low level since the last message.
Yesterday's target, the Southeastern limb region, was assigned a
number as NOAA 14379. However, the flare activity from this region
has diminished since the M class events yesterday, only a few low-C
class flares were produced including a C1.9 at 23:56 UT yesterday.
The region from the Northeastern limb, now designated as NOAA
14378 remains flare-quiet in the past 24 hours.
Today we will continue to observe NOAA 14379, the area close to
the Southeastern limb, because of the flare history since yesterday.
Additional C class events are expected.
The position of the target in NOAA 14379 on 26-February-2026 at
17:00 UT is: S20E81 (-895", -324").

Dear Collaborators,
Solar activity has been elevated to a moderate level since the last
message due to the flare activities from the region on the Southeast
limb. Although the sunspot associated with this region is not clearly
seen yet, this region has produced more than 20 low- to mid-C class
flares in the past 24 hours, with the largest being an M2.3 flare,
just occurred at 15:35 UT today (2/25).
There is a middle-sized sunspot rotated from the Northeastern limb,
which appears to be the returned NOAA 14366, the region produced an
X8.1 flare on 2/1. However, currently no flare is reported from this
Northeastern region.
Today we will continue to observe the Southeast limb region which has
no number assigned yet. Additional mid-C to low-M class events are
expected.
The position of the target on 25-February-2026 at 17:00 UT is:
S20E87 (-907", -333").
