Dear Collaborators,
Solar activity has been at a moderate level since the last
message. The largest event for the past 24 hours was an
M1.3 flare at 02:01 UT today produced by a newly emerged
region NOAA 13964 (N07W27). 13964 also produced eight
C-class flares and has been designated as a beta/D-type
configuration. The target region NOAA 13961 was the source
of an M1.1 flare (at 03:08 UT today) and two high C-class
flares. It retains a beta-gamma/E-type sunspot group. Today
we will continue to watch NOAA 13961. Additional low M-class
flares are probable from NOAA 13961 and 13964 in the next
24-hour period.
The position of NOAA 13961 on January 17 at 08:30 UT is:
S09E40 (-621", -90")

Dear Collaborators,
Solar activity has increased a little bit. NOAA 13961 was the
source of about ten low C-class flares, being the most productive
region in the past 24 hours. This region has been designated
as a beta-gamma/E-type configuration with increasing the
sunspot area and number of spots. Today we will watch this region.
Yesterday's target NOAA 13962 (N17E63) was designated as a
beta-gamma-delta/E-type but has been flare quite. Please note
that NOAA 13963 (N24E01, beta/C-type) produced three C3 flares
during the period. Further C-class flares are expected in the next
24 hours.
The position of NOAA 13961 on January 16 at 08:30 UT is:
S09E53 (-771", -104")

Dear Collaborators,
Solar activity continues to be at a low level. The largest event
since the last message was a C6.2 flare at 15:15 UT yesterday
produced by a newly numbered limb region, NOAA 13962.
13962 also produced three ~C2 flares during the period. Due to
its activity history, 13962 will become today's target, though it
was only designated as an alpha/H-type configuration. Also note
that another region NOAA 13961 (S09E65, beta/D-type) was the
source of four low C-class flares. Additional C-class activities are
expected in the next 24-hour period.
The position of NOAA 13962 on January 15 at 08:30 UT is:
N17E77 (-909", 301")

Dear Collaborators,
Solar activity continues at a low level. The target region
NOAA 13947 was the source of five low C-class flares in
the past 24 hours, the largest one being a C3.4 at 01:46 UT
today. Some other regions including NOAA 13959 and an
east limb region also produced a few ~C2 flares. Today we
will continue to watch NOAA 13947 for a final 24 hours. It
was designated as a beta-delta/D-type configuration. Further
C-class activities are expected in the following 24 hours.
The position of NOAA 13947 on January 14 at 12:30 UT is:
N11W84 (952", 193")

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:
N13W56 (789",259")

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:

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")
