Dear Collaborators,
Solar activity from the earth-facing side has been very low.
The largest event was a C5.2 flare from NOAA 14336 at 12:42 UT
today(1/12). However, an M3.4 flare was reported from the region
behind the Southeast limb at 21:53 UT yesterday. This flare
developed post flare arcades and a cusp at the latitude range of
South 10 to 15 degrees for several hours after the flare.
Although the sunspots associated with this event are still located
behind the limb, we will observe this region as the default target
today, expecting additional flares of C to M class.
The position of the target region on 12-January-2026 at 17:00 UT
is: S13E90 (-959", -223").

Dear Collaborators,
Solar activity has remained at a low level. NOAA 14337
produced the largest event, a C3.8 flare at 20:24 UT, and
four low-C plus high-B flares. It has been classified as a
beta/C-type sunspot group as it transited beyond the northwest
limb. Today, the target will switch to 14337. Yesterday’s target
only produced a ~C2 flare. More low-C flares are probable in
the next 24 hours.
The position of NOAA 14337 on 11-Jan-2026 12:30 UT is:
N25W81 (873", 421")

Dear Collaborators,
Solar activity has returned to a low level. The largest event
since the last message was a partially occulted C1.3 flare at
22:30 UT yesterday produced by NOAA 14323, which has
completely rotated beyond the southwest limb. NOAA 14339
was a newly-emerged active region, being classified as a
beta/B-type sunspot group. It produced the two ~C1 and a ~B7
flares. To the northeast of 14339, NOAA 14336 (S10E08,
beta-delta/E-type) also produced a C1 flare. 14339 (with 14336
in the field of view) becomes the new target. More low-C flares
are possible in the following 24 hours.
The position of NOAA 14339 on 10-Jan-2026 12:30 UT is:
S14W02 (33", -169")

Dear Collaborators,
Solar activity has increased slightly in the last 24 hours.
The largest event was a long duration C5.6 flare at 16:18
UT yesterday produced by the target region NOAA 14334.
It also produced a ~C3 flare and has been classified as a
beta/D-type magnetic configuration. Today the target shall
continue as 14334. In addition, NOAA 14336 has retained
a beta-gamma-delta/E-type sunspot group with an increase
in its spot area, but only produced several low-C flares for
several days, . Additional C-class flares are expected in the
following 24 hours.
The position of NOAA 14334 on 9-Jan-2026 12:30 UT is:
S16W13 (211", -206")

Dear Collaborators,
Solar activity has dropped to a low level in the past 24 hours.
The target region NOAA 14334 produced three low-C flares,
including the largest event being a C4.4 flare at 05:24 UT today.
It has been classified as a beta-gamma/C-type magnetic
configuration, with the emergence of additional spots. Today
the target shall remain with 14334. More C-class activity is
expected within the next 24 hours.
The position of NOAA 14334 on 8-Jan-2025 12:30 UT is:
S16W00 (0", -206")

Dear Collaborators,
Solar activity has grown to an intermediate level since the
last message. The largest event was a C7.4 flare at 06:06 UT
today from NOAA 14334. This region emerged as the most
productive, generating a total of eight flares. It degenerated
into a unipolar sunspot group and showed signs of fragmentation
during the period. Today 14334 becomes the new target.
Yesterday’s target NOAA 14323 (S17W76, beta/D-type) was
the source of only one low-C flare as it rotated toward the
southwest limb. Further C-class activity is possible over the
coming 24 hours.
The position of NOAA 14334 on 7-Jan-2025 12:30 UT is:
S15E13 (-212", -192")

Dear Collaborators,
The level of solar activity has increased slightly. The largest
event since the last message was a C4.0 flare at 07:45 UT
today from NOAA 14323. This region also produced three ~C2
flares. It retained a beta/D-type sunspot group, displaying the
magnetic signs of decay. Yesterday’s target, NOAA14325
(S08W69, beta/E-type), also has experienced a further decay
and became quiescent during this period. Today, the target
shall switch to 14323 from 14325. Note that NOAA 14336
(S09E61, beta/E-type) also produced a low-C flare, with new
spots emerging in its intermediate portion. More low-C activity
is expected in the next 24 hours.
The position of NOAA 14323 on 6-Jan-2026 08:30 UT is:
S16W61 (821", -240")

Dear Collaborators,
Solar activity has dropped to a low level. The target region
NOAA 14325 produced four low-C flares in the past 24 hours,
with its largest being a C2.0 flare at 21:27 UT yesterday. This
region has been classified as a beta-gamma/F-type sunspot
group. Close to the southeast of 14325, NOAA 14323 (S15W49,
beta/D-type) was also the source of two low-C flares. Today,
14325 shall continue as the target. Interested observers should
try to include 14323 in their field-of-view as well if possible. In
addition, NOAAs 14334 (S17E43, alpha/H-type), 14336 (S09E72,
alpha/H-type), and 14324 (N26W45, beta/C-type) also produced
a few low-C flares. Additional low-C activity is expected in the
following 24 hours.
The position of NOAA 14325 on 5-Jan-2025 08:30 UT is:
S08W56 (802", -102")

Dear Collaborators,
Solar activity has grown to an intermediate level since the
last message. The largest event was a C8.3 flare at 17:23 UT
yesterday from NOAA 14325. This region also produced three
low-C flares and has retained a beta-gamma/E-type magnetic
configuration, with the sunspot area of 300 μh. Yesterday’s
target NOAA 14324 (N24W33, beta/D-type) was only the
source of three low-C flares with a significant decay in its
spot area to 70 μh. Today, we will end the Major Flare Watch
campaign, and the default target switch back to NOAA 14325
due to its high magnetic complexity and large spot area. Further
C-class activity is probable in the coming 24 hours.
The position of NOAA 14325 on 4-Jan-2025 08:30 UT is:
S08W43 (660", -94")

Dear Collaborators,
Solar activity has been at a low level. The largest event since
the last message was a C3.1 flare at 01:27 UT today from the
target region NOAA 14324. This region has been classified as
a beta-delta/D-type sunspot group, but it seems to display
magnetic signs of decay. Today, we will extend the Major Flare
Watch with NOAA 14324 for the last 24 hours. More low-C
activity is expected, with a slight chance for an >M5 flare in
the next 24 hours.
The position of NOAA 14324 on 3-Jan-2025 12:30 UT is:
N24W22 (335", 445")
