Dear Collaborators,
Solar activity has increased to a moderate level since the last
message. The largest event in the last 24 hours was an M1.2 flare at
9:40 UT today(3/13) from NOAA 14384 approaching the Northwest limb.
The trailing portion of this region underwent further significant
flux emergence to grow the new sunspot to a comparable size with its
original leading sunspot. Three low-to-mid C class flares were also
reported from this region in the last 12 hours, while yesterday's
target, NOAA 14393 only produced two low-C class flares since the
last message.
Today, we will switch our target to NOAA 14384, expecting additional
C to M class events during its Northwest limb transit.
The position of the target in NOAA 14384 on 13-March-2026 at 16:00 UT
is: N09W72 (905", 195").

Dear Collaborators,
Solar activity has slightly increased from the last message.
The largest event in the last 24 hours was a C4.0 flare at 10:19 UT
today(3/12) from NOAA 14384 approaching the Northwest limb. This
region added new sunspots in its South and East vicinity during the
last 24 to 48 hours.
Yesterday's target, the trailing portion of NOAA 14389 was reassigned
the number, NOAA 14393. This region also added new sunspots in its
Northwest vicinity, and produced a C1.6 flare at 11:40 UT today.
In the next 24 hours, we will continue to observe NOAA 14393 on the
area of new flux emergence, Northwest side of the main sunspot.
Additional C class activities are expected.
The position of the target in NOAA 14393 on 12-March-2026 at 16:00 UT
is: N14E41 (-624", 328").

Dear Collaborators,
Solar activity has been at a very low level since the last message.
The largest event in the last 24 hours was a C4.7 flare at 18:32 UT
yesterday(3/10) from NOAA 14381, which is undergoing the Northwest
limb transit today.
Yesterday's target, the Northeast limb region, has registered as
NOAA 14389. This region produced two near C-class flares (a C1.1 at
00:56 UT and a B9.1 at 10:06 UT) today. There was a new flux emergence
in the Southeast vicinity of NOAA 14387, which so far produced only
a B8.0 event at 9:36 UT today.
In the next 24 hours, we will continue to observe NOAA 14389 on its
trailing sunspot.
The position of the target in NOAA 14389 on 11-March-2026 at 15:00 UT
is: N12E56 (-781", 280").

Dear Collaborators,
Solar activity has slightly increased from the last message.
The largest event in the last 24 hours was a C7.9 flare at 20:21 UT
yesterday(3/9) from the target region, NOAA 14387. This region also
produced two more near C-class flares, however reduced in sunspot
area and appears to be in the process of decay.
The Northeast limb region in the East of NOAA 14387, has fully come
into our view but yet unnumbered. This region produced 4 low-C class
flares in the period from the area of its trailing sunspots. Today
we will switch the default target to this unnumbered region, due to
its recent flare history.
The position of the target on 10-March-2026 at 15:00 UT is:
N13E68 (-872", 263").

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")
