Dear Collaborators,
Solar activity is at a low-moderate level. NOAA 14366 was the site of
several M-class flares, the largest being two partially occulted M1.4
flares at 00:50 and 12:47 UT today, respectively. As NOAA 14366 traverses
the northwestern limb, it continues to show signs of emerging flux and
flare activity. While it remains in view, NOAA 14366 will continue to be
the target region. Further C-class activity is likely with the chance for
further occulted flares in the next 24 hours.
The position of NOAA 14366 on 11-February-2026 at 12:30 UT is
N14W91, (942", 231")

Dear Collaborators,
Solar activity has reduced slightly. NOAA 14366 produced over ten C-class
flares in the last 24 hours, but the largest flare produced since the last
message was a C9.2 from NOAA 14374 at 18:01 UT yesterday. NOAA 14366 has
begun its transit of the northwest limb, at this time, it remains
classified as a beta-gamma-delta. The region shows substantial coronal flux
and should be monitored closely during its progression over the solar limb.
Further C-class flares are expected with a chance for isolated M-class
activity.

Dear Collaborators,
Solar activity continues at an elevated level. Several flares have been
produced since the last message, the largest being an M2.8 from NOAA 14366
at 02:14 UT today. NOAA 14366 remains classified as a beta-gamma-delta as
it begins its approach of the northwestern limb. The region continues to
show signs of emerging flux and is likely to produce further activity over
the next 24 hours. NOAA 14366 will continue as the target region,
additional C-class is expected with a chance for further isolated M-class
events.

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The largest event during the period was an M2.7 flare at 13:46 UT today
from NOAA 14366 (N14W53; beta-gamma-delta/F-type). This region also
produced two additional ~M2 flares and several C-class flares during the
period. We will continue monitoring NOAA 14366 today. C-class activity
is expected over the next 24 hours, with a chance of additional low M-class
events.
The position of NOAA 14366 on 8-Feb-2026 12:30 UT is:

Dear Collaborators,
Solar activity has declined to a low level since the last message.
The largest event during the period was a C7.3 flare at 08:09 UT
today from NOAA 14362 (S17W40; beta/C-type). The target region
NOAA 14366 (N14W38) remains a beta-gamma-delta configuration
and produced seven low C-class flares during the period, the largest
of which was a C4.2 flare. We are ending the Major Flare Watch,
but we will continue to monitor NOAA 14366 as the target region
due to significant ongoing 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 14366 on 7-Feb-2026 08:30 UT is:
N14W38 (582",318")

Dear Collaborators,
Solar activity has decreased slightly since the last message. The largest
event during the period was an M2.2 flare at 19:28 UT yesterday from
NOAA 14362 (S17W27; beta/C-type). This region also produced an M1.8
flare and a few C-class flares during the period. The target region NOAA
14366 (N14W24) produced three ~M2 flares and several C-class flares.
14366 remains a beta-gamma-delta/F-type sunspot group with an area of
1100 µh, and is undergoing significant flux emergence in its trailing and
central portions. Today, the Major Flare Watch will continue to focus on
NOAA 14366. Low M-class activity is expected, with a chance of an
isolated >M5 flare within the next 24 hours.
The position of NOAA 14366 on 6-Feb-2026 08:30 UT is:

Dear Collaborators,
Solar activity has dropped to a moderate level since the last
message. Seven low-M and seven C-class flares were
produced by the target region NOAA 14366, with the largest
magnitude being an M2.7 at 04:25 UT today. This region has
retained a beta-gamma-delta/F-type sunspot group with an
area of >1000 μh, showing the emergence of shearing and
rotational magnetic fluxes in its intermediate portion. Today,
the Major Flare Watch region will continue at 14366. Low-M
activity is expected, with a chance for an isolated >M5 flare
in the coming 24 hours.
The position of NOAA 14366 on 5-Feb-2026 08:30 UT is:

Dear Collaborators,
Solar activity has returned to a very high level in the past
24 hours. The target region NOAA 14366 produced an
~M7 and two X-class flares, including the largest being an
X4.2 at 12:02 UT. This region appears to have diminished
in the number of spots, after it increased in area to 1100 μh
and was classified as a beta-gamma-delta/F-type sunspot
group. Today, the Major Flare Watch region will remain with
14366. More M-class activity is expected, with another
X-class flare probable in the next 24 hours.
The position of NOAA 14366 on 4-Feb-2026 12:30 UT is:

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 μh, 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:

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.
