Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The largest event during the period was an M3.4 flare at 06:53 UT today
from NOAA 14349 (S16E17, beta/C-type). Yesterday’s target, NOAA
14341 (S11W14), has remained flare-quiet throughout the period and
has continued to decrease in magnetic complexity; it is now classified
as beta/D-type. Nearby region NOAA 14345 (S17W07) produced an
M1.2 flare along with several low C-class flares. Today, we will end the
Major Flare Watch campaign, and the default target will switch to NOAA
14345 due to its ongoing significant flux emergence. Additional C-class
activity is expected over the next 24 hours, with a chance of low M-class
events.
The position of NOAA 14345 on 21-Jan-2026 08:30 UT is:
S17W07 (114",-201")

Dear Collaborators,
Solar activity has decreased to an intermediate level since the last
message.
The largest event during the period was a C8.0 flare at 19:09 UT yesterday,
attributed to NOAA 14342 (N14E03, beta/D-type). However, flares from other
regions (e.g., NOAA 14349) also contributed to the soft X-ray flux. Target
region NOAA 14341 has remained flare-quiet throughout the period and has
decreased in magnetic complexity, now classified as beta-gamma/D-type.
Nearby region NOAA 14345 produced several C-class flares during the period.
The Major Flare Watch campaign will continue for a final 24 hours for NOAA
14341 due to its flare history. If possible, please also include NOAA 14345
in
your field of view. Further C-class activity is expected, with a chance of
an
isolated >M5 flare within the next 24 hours.
The position of NOAA 14341 on 20-Jan-2026 12:30 UT is:
S11W04 (67",-101")

Dear Collaborators,
Solar activity has decreased slightly since the last message. The largest
event during the period was an M1.2 flare at 11:09 UT today from NOAA
14345 (S16E17, beta/C-type), located near the target region NOAA 14341
(S11E10). 14341 has been flare-quiet since yesterday’s X1.9 flare, but this
region has evolved into a beta-gamma-delta magnetic configuration with
ongoing flux emergence. Today, we will extend the Major Flare Watch with
NOAA 14341 for the next 24 hours. Further C-class activity is expected,
with a chance for >M5 flares in the next 24-48 hours.
The position of NOAA 14341 on 19-Jan-2026 12:30 UT is:
S11E10 (-166",-104")

Dear Collaborators,
An X1.9 flare was produced by NOAA 14341 at 17:27 UT today (1/18).
The flare started from the South of main (negative polarity) sunspots,
at the location of the filament adjacent to the Southwesternmost (positive)
sunspot. At this time, we will implement a Major Flare Watch campaign
with NOAA 14341. Additional major flares larger than M5 are expected
in the next 24 to 48 hours.
The position of the target region in NOAA 14341 on 18-January-2026
at 22:00 UT is: S11E17 (-294", -124").
This X1.9 event is well summarized at the following page.

Dear Collaborators,
Solar activity has slightly decreased from the last message.
The target region, NOAA 14341 produced an M1.2 flare at 23:46 UT
yesterday(1/17) from the area of mixed polarity in the West vicinity
of the main sunspot. In addition, 2 C class flares were from this
region, while a C7.2 event at 06:01 UT today was from the East side
of the main sunspot. NOAA 14242 in the Northern hemisphere is another
source of flares in the past 24 to 48 hours, but these events are currently
at a low-C level.
Although NOAA 14341 is reducing the area (840 to 500 millionths), it
maintains flare activity of high-C to M class. Today, we will continue to
observe NOAA 14341, at the West side of the main spots.
The position of the target region in NOAA 14341 on 18-January-2026
at 17:00 UT is: S09E20 (-333", -86").

Dear Collaborators,
Solar activity has increased to a moderate level since the last
message. Yesterday's target, NOAA 14343 produced 5 C class flares
after the message, with the largest being a C5.2 at 22:58 UT
yesterday (1/16). However it has been flare-quiet during the recent
12 hours, although it maintains clear sigmoidal loops.
The largest event in the past 24 hours was an M2.2 flare at 10:19 UT
today produced by NOAA 14341 from its Northwest area. NOAA 14341
has reached the size of 840 millionths, and added magnetic complexity
to a beta-gamma-delta type. There is an area of mixed polarity in the
West vicinity of the main largest sunspot, that repeats brightenings
including a few C class flares by itself and the ones associated with
the flares reported from the closely adjacent region NOAA 14345.
In the next 24 hours, the target region will switch back to NOAA
14341 at the area of mixed polarity in the West of the main sunspot.
Additional C to M class flares are expected.
The position of the target region in NOAA 14341 on 17-January-2026
at 17:00 UT is: S10E33 (-530", -104").

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The largest event in the period was a C6.6 flare at 08:47 UT today
(1/16) produced by NOAA 14345, which emerged in the Southeast of
the target region, NOAA 14341. NOAA 14341 has been flare-quiet
in the past 24 hours.
NOAA 14343 is the region that emerged two days ago at the latitude
of 10 degrees South, and is growing rapidly in size to over 100
millionths with magnetic configuration of a beta-gamma type. This
region has only produced a C1.3 flare so far, but the loops are
showing a solid sigmoidal shape in high temperature EUV wavelengths.
Today, we will switch the target to NOAA 14343 expecting the
increasing activity of C class or larger.
The position of the target region in NOAA 14343 on 16-January-2026
at 17:00 UT is: S11W01 (17", -122").

Dear Collaborators,
Solar activity has further increased to a moderate level since the
last message. The largest event in the period was an M1.6 flare at
20:10 UT yesterday (1/14) produced by the target region, which was
registered as NOAA 14341. This region also produced a C9.8 flare
at 6:20 UT today and 3 more low-C class flares in the past 24 hours.
NOAA 14341 underwent new flux emergence in the Southwestern
vicinity of the main sunspot area with negative polarity, which appears
to be the source of recent flares from this region. Today, we will
continue to observe NOAA 14341 at the Southwest side of the main
negative sunspots, expecting additional C to M class events.
The position of the target in NOAA 14341 on 15-January-2026 at
17:00 UT is: S11E61 (-837", -165").

Dear Collaborators,
Solar activity has slightly increased since the last message, but
still at a low level. The largest event was a C9.6 flare at 3:34 UT
today(1/14) from the region being rotated from the Northeast limb.
This region is connected with the target region in the Southern
hemisphere through the trans-equatorial loops, and is producing
a few low-C class flares after the C9.6 envent.
The target region has completed the Southeast limb passage and its
sunspots have come into earth's view. Although it is still too close
to the limb to figure out the size and magnetic configuration, it
appears to be formed by multiple spots with the total area being larger
than that of NOAA 14336. Currently this region and the region from
the Northeastern limb, both of which are yet unnumbered, are
alternatively producing C class flares.
Today, we will continue to observe the target region from the
Southeast limb, since the main body of the Northeast region appears
to be still behind the limb. Additional C class events are expected
from both regions.
The position of the target region on 14-January-2026 at 17:00 UT
is: S09E75 (-928", -146").

Dear Collaborators,
Solar activity has been very low since the last message. The largest
event was a C2.0 flare at 9:13 UT today(1/13) from the the Southeast
limb region that produced an M3.4 flare on 1/11. The sunspots of
this region are still behind the limb, but high loop system including
the trans-equatorial loops connected to the Northern hemisphere is
visible in the EUV wavelengths. Several high-B to low-C flares were
reported from this region, while the regions on the disk only produced
a C1.5 flare (by NOAA 14336) in the past 24 hours. Today, we will
continue to observe the Southeast limb region expecting additional
C class activities or larger.
The position of the target region on 13-January-2026 at 17:00 UT
is: S11E86 (-953", -191").
