Dear Collaborators,
Solar activity remains at a moderate level. The largest event since
the last message was an M2.0 flare at 18:45 UT yesterday (11/18),
produced by the target region, which has been numbered as NOAA
13901 (S07E56, beta-gamma/D-type). This region also produced
an M1.8 flare and three C-class flares in the period. The Major Flare
Watch shall remain effective with NOAA 13901 over the next 24 hours
due to continued flux emergence. Additionally, regions near the southeast
limb, NOAA 13889 (S09W88), 13897 (S12W69), and 13895 (S03W71),
also produced two M1.1 flares and several C-class flares during the
period. Further M-class flares are expected, with a chance of >M5
flares from the limb regions in the next 24-48 hours.
The position of NOAA 13901 on 19-Nov-2024 at 12:30 UT is:
S07E56 (-800",-140")

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The largest event in the period was an M3.7 flare at 12:42 UT today
(11/18), produced by the limb target region (S06E73, still unnumbered).
This limb region was also the source of another four M-class flares (M1.0,
M1.7, M1.3, and M2.5) and several C-class flares in the period. At this
time, we are implementing the Major Flare Watch campaign with the
southeast limb region. Additionally, two regions near the southwest limb,
NOAA 13897 (S12W54) and 13889 (S09W78), also produced several
C-class flares and an M1.6 flare in the period. Further M-class flares are
expected, with a chance of >M5 flares from the limb regions in the next
24-48 hours.
The approximate position of the target on 18-Nov-2024 at 12:30 UT is:
S06E73, ( -924", -113" )

Dear Collaborators,
Solar activity has decreased to a low level since the last message.
The largest event in the period was a C5.4 flare at 10:38 UT today
(11/17), produced by a southeast limb region (S09E89), which also
produced another six C-class flares in the period. The target region
shall switch to this limb region. Yesterday's target NOAA 13892
(S11W50, alpha/A-type) produced three low C-class flares in the
period, while the nearby region NOAA 13889 (S09W64, beta-gamma
-delta/F-type) produced a C4.5 flare during the decay phase of the
C5.4 flare. Further C-class activity is expected, with a chance of low
M-class flares in the following 24-48 hours.
The approximate position of the target on 17-Nov-2024 at 12:30 UT is:
S09E89, ( -958", -152" )

Dear Collaborators,
Solar activity has slightly increased since the last message.
Yesterday's target region NOAA 13889 (S09W50) only produced
a low C-class flare during the period, although it retains a beta-
gamma-delta/F-type configuration. The largest event in the period
was an M1.6 flare at 01:26 UT today (11/16), produced by NOAA
13892 (S11W36, beta/B-type), which was also the source of
another six C-class flares. Today, the target region shall switch
to this region. Additionally, NOAA 13893 (S19E27, beta/C-type)
also produced an M1.0 flare in the period (12:05 UT, 11/15).
Further low M-class activities are expected in the next 24 hours.
The position of NOAA 13892 on 16-Nov-2024 at 12:30 UT is:
S11W36 (561",-221")

Dear Collaborators,
Solar activity remains at an intermediate level. The largest event since
the last message was an M1.1 flare at 01:38 UT today (11/15), produced
by NOAA 13893 (S19E43, beta/C-type). The target region NOAA 13889
(S09W34, beta-gamma-delta/F-type) and its nearby regions, NOAA 13892
(S11W20) and 13891 (S15W47), produced five low C-class flares in the
period. At this time, we are ending the Major Flare Watch, but NOAA 13889
shall remain the target region, due to its magnetic complexity and prior
flaring history. Further C-class activities are expected, with a chance of
low M-class flares in the next 24 hours.
The position of NOAA 13889 on 15-Nov-2024 at 08:30 UT is:
S09W34 (537",-190")

Dear Collaborators,
Solar activity has slightly increased since the last message. The target
region NOAA 13889 (S10W20) continues to be the most flare-productive
region on the disk, being the source of seven C-class flares and the
largest magnitude flare in the period - an M1.7 at 16:57 UT yesterday
(11/13). 13889 retains a beta-gamma-delta magnetic configuration,
which is emerging new flux in its trailing portion. The Major Flare Watch
shall remain in effect with NOAA 13889 for a further 24 hours due to the
possibility of an >M5 flare.
The position of NOAA 13889 on 14-Nov-2024 at 08:30 UT is:
S10W20 (327",-214")

Dear Collaborators,
Solar activity has increased to an intermediate level since the last message.
The largest event was an M1.0 flare at 00:11 UT today (11/13), produced
by the target region NOAA 13889 (S09W07). This region retains a beta-
gamma-delta magnetic configuration and produced another eight C-class
flares in the period. The Major Flare Watch will remain effective with NOAA
13889 for the next 24 hours, due to its magnetic complexity and increasing
activity. Please note that NOAA 13879, which recently rotated beyond the
west limb, produced a C8.3 flare at 12:36 UT yesterday (11/12). Additional
C-class activity is expected, with a chance of an isolated >M5 flare in the
next 24-48 hours.
The position of NOAA 13889 on 13-Nov-2024 at 08:30 UT is:

Dear Collaborators,
Solar activity has decreased to a low level since the last message.
The target region NOAA 13889 (S10E06) remains the most flare-
productive region during the period. It retains a beta-gamma-delta
sunspot group and was the source of eight C-class flares, including
the largest magnitude in the period - a C4.4 at 14:19 UT yesterday
(11/11). The Major Flare Watch will remain effective with NOAA
13889 for a further 24 hours, due to its magnetic complexity and
prior flaring history. Please note that NOAA 13884 (S07W47, beta/
C-type) also produced a C4.3 flare at 07:40 UT today. Further
C-class activities are expected, with a slight chance of an isolated
>M5 flare in the next 24 hours.
The position of NOAA 13889 on 12-Nov-2024 at 08:30 UT is:
S10E06 (-100",-220")

Dear Collaborators,
Solar activity has decreased to a high-to-moderate level since the last
message. The largest event in the period was an M4.9 flare at 20:09 UT
yesterday (11/10) produced by the target region NOAA 13889 (S10E21).
This region retains a beta-gamma-delta magnetic configuration with a
slight increase in the spot area (now 480 μH). 13889 also produced
an M1.4 flare at 05:36 UT today and several C-class flares during the
period. Today the Major Flare Watch shall remain with NOAA 13889,
due to its magnetic complexity, high current helicity, and continued
flux emergence. M-class activities are expected, with a chance of an
isolated >M5 flare in the next 24-48 hours.
The position of NOAA 13889 on 11-Nov-2024 at 12:30 UT is:
S10E21 (-343",-219")

Dear Collaborators,
Solar activity has returned to a high level, due to an M9.4 flare
at 11:51 UT today produced by NOAA 13889. 13889 retains a
beta-gamma-delta/E-type sunspot group and has increased in
the spot area to 450 μh. Today the Major Flare Watch shall switch
to NOAA 13889 because of its high complexity, and large size,
and return to M-class flaring. Yesterday’s target NOAA 13883
(S06W42, beta-gamma-delta/F-type) was flare quiet over the
period. Additional low-M activities are probable, with a chance
for another >M5 flare in the next 24 hours.
The position of NOAA 13889 on 10-Nov-2024 at 12:30 UT is:
S10E31 (-493", -216")
