Dear Collaborators,
Solar activity remains low since the last message. The largest event
in the last 24 hours was a C2.3 flare at 12:48 UT today(3/9) from
from NOAA 14381. This region also produced 3 low-C class flares since
yesterday, but is showing a sign of decay.
Yesterday's target, rorated from the Northeast limb, was assigned
the number as NOAA 14387. Two low-C class flares are attributed to
this region, but one of them is from closer to the limb, suggesting
a separate region is rotating from the Northeast limb.
Today, we will continue to observe NOAA 14387 at the area of trailing
sunspots, the source of the C1.7 event at 08:01 UT today. Additional C
class events are expected.
The position of the target in NOAA 14387 on 9-March-2026 at 16:30 UT
is: N09E59 (-820", 220").

Dear Collaborators,
Solar activity has remained low since the last message. The largest
event during the period was a C2.1 flare at 15:02 UT today from an
unnumbered region near the northeast limb (N08E69). This region
also produced four additional ~C1 flares. Yesterday’s target NOAA
14381 (N08W33, beta/E-type) produced only two high B-class flares
in the period. Today, the target will switch to the unnumbered limb
region because of its recent flare activity. Additional low C-class
activity
is expected over the next 24 hours.
The approximate position of the target on 8-March-2026 at 12:30 UT is:
N08E67, (-882", 181")

Dear Collaborators,
Solar activity has remained low since the last message. The largest
event during the period was a C1.2 flare at 12:59 UT yesterday from
an unnumbered region near the northeast limb (N06E88). NOAA
14378 and NOAA 14385 each also produced a ~C1 flare during the
period. The target region NOAA 14381 (N08W18, beta/E-type) produced
only a few high B-class flares during the period, but its trailing portion
continues to show signs of flux emergence. Today, we will continue to
observe NOAA 14381 as the default target with a focus towards its
trailing portion. Additional low C-class activity is possible over the next
24 hours.
The position of NOAA 14381 on 7-March-2026 at 12:30 UT is:
N08W18, (296",249")

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").
