Dear Collaborators,
Solar activity continues at a low level. The largest event
since the last message was a C8.1 at 02:05 UT today
produced by the target region NOAA 13947. 13947 retains
a beta-gamma/D-type configuration. Note that some other
regions including NOAA 13948, 13951, and 13959 produced
a few low C-class flares in the period. Today we will continue
to watch NOAA 13947 before it rotates over the west limb.
Further C-class activities are expected in the next 24 hours.
The position of NOAA 13947 on January 13 at 12:30 UT is:
N11W70 (900", 210")

Dear Collaborators,
Solar activity has dropped to a very low level since the last message.
The largest event was a C1.8 flare yesterday at 20:19 UT from NOAA
13945 (S07W79). The target region NOAA 13947 (N13W56) produced
only a C1.7 flare yesterday. This region maintains a beta-gamma
configuration and shall remain the target. Additionally, a southeast
region (S06E64, unnumbered yet) produced two low C-class flares
(C1.5 and C1.7) in the period. Further C-class activity is expected,
with a slight possibility of an isolated low M-class flare in the next 24
hours.
The position of NOAA 13947 on 12-Jan-2025 at 08:30 UT is:

Dear Collaborators,
Solar activity has slightly increased since the last message.
The largest event was an M1.0 flare at 22:29 UT yesterday
from the target region NOAA 13947 (N13W42, beta-gamma
/D-type). Today, the target shall remain NOAA 13947. Besides,
a northeast limb region (currently unnumbered, N05E24)
produced three low C-class flares. Further C-class activity is
expected, with a chance for another isolated low M-class flare in
the next 24-48 hours.
The position of NOAA 13947 on 11-Jan-2025 at 08:30 UT is:

Dear Collaborators,
Solar activity has decreased to a low level since the last message.
The largest event in the period was a C6.2 flare at 09:24 UT today,
produced by a spotless region NOAA 13951 (S15W46, beta/B-type),
which also produced two additional low C-class flares in the period.
The target region NOAA 13947 (N12W27) remains the most flare-
productive region during the period, although it was downgraded
to a beta-gamma region. 13947 produced seven C-class flares in
the period, including a C5.0 flare. Today, NOAA 13947 shall remain
the target region. Further C-class activity is expected, with a chance
for an isolated low M-class flare in the following 24 hours.
The position of NOAA 13947 on 10-Jan-2025 at 08:30 UT is:

Dear Collaborators,
Solar activity has remained at a moderate-to-low level since the
last message. The largest event in the period was an M1.1 flare
at 00:18 UT today, produced by the target region NOAA 13947
(N12W14). This region retains a beta-gamma-delta configuration
and was the source of another three low C-class flares. NOAA
13947 shall remain the target region today, with further C-class
activity expected and a possibility of low M-class flares in the
next 24 hours.
The position of NOAA 13947 on 9-Jan-2025 at 08:30 UT is:
N12W14 (231",267")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since the last
message. The largest event in the period was an M1.1 flare at
22:35 UT yesterday, produced by a southwest limb region NOAA
13939 (S20W88). Additionally, NOAA 13950 (S18E17, alpha/H-type)
produced a C9.8 flare at 06:29 UT today. The target region NOAA
13947 (N12W02) produced only three low C-class flares in the
period, although it retains a beta-gamma-delta configuration.
At this time, we are ending the Major Flare Watch campaign,
but NOAA 13947 shall remain the target region, due to its
magnetic complexity and activity history. Further C-class activity
is expected, with a chance of low M-class flares in the next 24 hours.
The position of NOAA 13947 on 8-Jan-2025 at 08:30 UT is:
N12W02 (33",267")

Dear Collaborators,
Solar activity has slightly increased since the last message.
The largest event in the period was an M4.8 flare at 16:12 UT
yesterday, produced by the target region NOAA 13947 (N11E12).
This region maintains a beta-gamma-delta configuration, with
a slight increase in the sunspot area and number of spots.
13947 also produced several C-class flares in the period.
Today the Major Flare Watch shall remain with 13947 for a
further 24 hours, due to the possibility of an >M5 flare.
The position of NOAA 13947 on 7-Jan-2025 at 08:30 UT is:
N11E12 (-199",247")

Dear Collaborators,
Solar activity has dropped to a moderate level since the last message.
The largest event in the period was an M3.1 flare at 01:29 UT today,
produced by the target region NOAA 13947 (N11E24). This region
retains a beta-gamma-delta configuration but is diminishing in the
sunspot area and number of spots. 13947 also produced two additional
low M-class flares and over ten C-class flares in the period. Today
the Major Flare Watch shall remain with 13947 for a further 24 hours,
due to its activity history and magnetic complexity. Further low-M
activity is expected, with a chance for major flares (>M5) in the coming
days.
The position of NOAA 13947 on 6-Jan-2025 at 08:30 UT is:

Dear Collaborators,
Solar activity has slightly decreased since the last message.
The largest event in the period was an M4.2 flare at 02:14 UT
today, produced by the target region NOAA 13947 (N10E35).
This region has now developed into a beta-gamma-delta
configuration, with further increases in both sunspot area
and number of spots. 13947 also produced three mid-to-high
C-class flares and four low M-class flares in the period,
including an M4.1 at 09:09 UT today. The Major Flare Watch
shall remain in effect for this region. Further low-M activity is
expected, with a chance for >M5 major flares in the coming days.

Dear Collaborators,
Solar activity has remained high since the last message. The target
region NOAA 13947 (N11E52) produced a new X-class flare in the
period: an X1.1 flare at 22:32 UT yesterday. This region, classified
as a beta-delta configuration, has significantly increased in the
sunspot area. 13947 also produced two major flares (M5.8 and M7.6),
three low M-class flares, and six C-class flares during the period.
Today the Major Flare Watch will remain in effect with NOAA 13947.
Further M-class activity is expected, with a good chance for additional
major flares (>M5) in the following 24-48 hours.
The position of NOAA 13947 on 4-Jan-2025 at 08:30 UT is:
