Dear Collaborators,
Solar activity has dropped to a high-M level. The two largest
events since the last message were an M6.7 flare at 11:15 UT
yesterday and an M7.2 flare at 06:43 UT today, produced by
the target region NOAA 14366. This region has retained a
beta-gamma-delta/E-type and continued to increase in area to
730 ÎĽh, developing substantial new spots. More low-M activity
is expected, with a good chance for another >M5 flare in the
following 24 hours.
The position of NOAA 14366 on 3-Feb-2026 12:30 UT is:
N14E14 (-229", 334")

Dear Collaborators,
The level of solar activity has increased since the last
message. The target region NOAA 14366 has produced four
high-M and four X-class flares, including the largest magnitude
being an X8.1 at 23:44 UT yesterday. This productive region
has been classified as a beta-gamma-delta/E-type sunspot
group, showing the emergence of significant mixed and
shearing magnetic fluxes. More >M5 flares are very likely
in the coming days.
The position of NOAA 14366 on 2-Feb-2026 08:30 UT is:
N14E30 (-473", 322")

Dear Collaborators,
Solar activity has reached a very high level. NOAA 14366 has just
produced an X1.0 flare at 12:25 UT today.

Dear Collaborators,
Solar activity has increased further to a high level since the last
message. The largest event during the period was an M6.6 flare
at 09:53 UT today, produced by target region NOAA 14366 (N13E46).
The region also produced four additional low M-class flares and
more than ten C-class flares during the period. 14366 has evolved
into a beta-gamma-delta magnetic configuration, with significant
ongoing flux emergence. At this time, we are implementing the
Major Flare Watch campaign for NOAA 14366. Additional major
flares above M5.0 are likely over the next few days.
The position of NOAA 14366 on 1-Feb-2026 08:30 UT is:

Dear Collaborators,
Solar activity has increased further since the last message. The largest
event during the period was a C6.2 flare at 10:35 UT today, produced
by NOAA 14366 (N16E58, beta/D-type). This region also produced seven
other C-class flares, including C4.9 and C6.1 events. NOAA 14349 (S14W80)
also produced a C6.0 flare during the period. Yesterday’s target region,
NOAA 14363, produced only a C3.6 flare in the period. Today, we will
switch the target to NOAA 14366. Additional C-class activity is expected
over the next 24 hours, with a chance of an isolated low-level M-class
event.
The position of NOAA 14366 on 31-Jan-2026 12:30 UT is:

Dear Collaborators,
Solar activity has increased slightly since the last message.
The largest event during the period was a C1.9 flare at 10:26
UT today, produced by a northeast limb region (N13E74; not
yet numbered), which also generated two other ~C1 flares.
The newly emerged active region NOAA 14363 (S23E67) also
produced four ~C1 flares during the period. This region shows
magnetic connectivity to the nearby newly emerged region
NOAA 14362 (S17E65). Yesterday’s target region NOAA 14351
has rotated fully beyond the west limb. Today, we will switch the
target to NOAA 14363. Additional C-class activity is expected
over the next 24 hours.
The position of NOAA 14363 on 30-Jan-2026 12:30 UT is:
S23E67 (-826",-343")

Dear Collaborators,
Solar activity has remained very low. The largest event since the last
message was a C1.3 flare at 21:19 UT yesterday from NOAA 14357
(S13W27). The target region NOAA 14351 produced a few low-level
(possibly B-class) flares during the period. Today, we will continue to
monitor this region until it fully rotates over the west limb.
The position of NOAA 14351 on 29-Jan-2026 12:30 UT is:
S04W81 (959",-52")

Dear Collaborators,
Solar activity has decreased to a very low level since the last message.
Only four low C-class flares occurred in the period, the largest being a
C2.7 flare at 23:30 UT yesterday, attributed to NOAA 14342 (N14W88)
near the west limb. Target region NOAA 14351 has been flare-quiet
throughout the period. Today, we will continue to observe this region
until it completely rotates over the west limb.
The position of NOAA 14351 on 28-Jan-2026 12:30 UT is:
S05W68 (900",-48")

Dear Collaborators,
Solar activity has remained low. The largest event since the last
message was a C8.8 flare at 13:25 UT yesterday, produced by
NOAA 14355 (S12E11, beta/C-type). Yesterday’s target NOAA
14349 has been flare-quiet during the period and has decreased
in sunspot area and number of spots. NOAA 14351 produced a
number of C-class flares during the period, including a C5.0 flare.
Today, we will switch the target to NOAA 14351 due to its ongoing
significant flux emergence. Additional C-class activity is expected
over the next 24 hours.
The position of NOAA 14351 on 27-Jan-2026 12:30 UT is:
S05W54 (787",-28")

Dear Collaborators,
Solar activity has remained at a low level. The largest event since
the last message was a C7.9 flare at 21:36 UT yesterday, attributed
to NOAA 14344 near the northwest limb (N19W91). Yesterday’s
target NOAA 14353 has evolved into a beta-gamma configuration
and remained flare-quiet during the period. NOAA 14349 (S14W13,
beta/D-type) produced several C-class flares during the period,
including C4.5 and C4.9 events. Today, we will switch the target
to NOAA 14349 due to its flare history and its larger sunspot area
(230 uh). Additional C-class activity is expected over the next 24
hours.
The position of NOAA 14349 on 26-Jan-2026 12:30 UT is:
S14W13 (213",-145")
