Dear Collaborators,
Solar activity has been at a moderate level since the last
message. The target limb region has been numbered as
NOAA 13917 with a beta/C-type configuration. It produced
two low M-class flares, an M1.4 (being the largest one) at
20:57 UT yesterday and an M1.0 at 06:56 UT today, plus
four C-class flares. Also note that NOAA 13916 (S16E53,
beta/C-type) and 13906 (S17W91, beta-gamma/E-type)
also produced an M1.3 and an M1.1 flares, respectively.
Additional M-class activities are very likely in the following
24 hours.
The position of NOAA 13917 on December 5 at 08:30 UT is:
S09E56 (-798", -155")

Dear Collaborators,
Solar activity has increased since the last message. An M2.3 flare
was produced by an east limb region at 09:52 UT today. This limb
region also produced two C3 flares. Today we will watch this region.
Yesterday's target NOAA 13912 was flare quiet during the period.
Note that NOAA 13905 (S09W90, beta-gamma/E-type) and 13916
(S16E65, beta/C-type) were the sources of numerous C-class flares,
the latter of which just emerged yesterday. Further C-class activities
are expected with some chance of M-class flare in the next 24 hours.
The approximate position of the target on December 4 at 12:30 UT is:
S09E89 (-950", -150")

Dear Collaborators,
Solar activity continues at a low level. The largest event
of the period was a C5.4 flare at 02:56 UT today from
NOAA 13912. Today the target will switch to this region
due to its activity history. 13912 retains a beta-gamma/
E-type configuration but increases the sunspot area and
number of spots slightly. Yesterday's target NOAA 13906
seems to enter its decay phase and has been flare quiet
since the last message. Also note that a southeast limb
region (S15E89) produced four C-class activities during
the period. Only C-class activities are expected in the
following 24 hours.
The position of NOAA 13912 on December 3 at 04:30 UT is:
S05E24 (-395", -94")

Dear Collaborators,
Solar activity continues at a low level. The largest
event of the period was a C5.5 flare at 16:11 UT
yesterday produced by the target NOAA 13906.
13906 also produced two ~C2 flares. It retains a
beta-gamma/E-type configuration. Further C-class
activities are expected in the next 24 hours.
The position of NOAA 13906 on December 2 at 08:30 UT is:
S16W54 (758", -275")

Dear Collaborators,
Solar activity continues at a low level. The largest event since the
last message was a C9.4 flare at 08:59 UT yesterday produced by
the target NOAA 13906. 13906 also produced six other low C-class
flares. This region retains a beta-gamma/E-type configuration but
decreases the sunspot area and number of spots. Today we will
continue to watch this region. Further C-class activities are expected
in the following 24 hours.
The position of NOAA 13906 on December 1 at 12:30 UT is:
S16W42 (627", -278")

Dear Collaborators,
Solar activity continues at a low level for the past 24 hours.
The largest event of the period was a C5.6 flare at 05:56 UT
today produced by NOAA 13906. 13906 also produced another
seven C-class flares in the period. The other low C-class flares
were produced by some other regions, e.g., NOAA 13902 and
13905 etc. Yesterdays' target NOAA 13912 was designated to
be a beta/D-type configuration and has been flare quiet since
the last message. Today the target will switch to NOAA 13906
due to its flare history, which has a beta-gamma/E-type sunspot
group. Further C-class flares are expected in the next 24 hours.
The position of NOAA 13906 on November 30 at 08:30 UT is:
S16W26 (411", -282")

Dear Collaborators,
Solar activity has been at a very low level. The largest event since
the last message was a C5.4 flare from NOAA 13908 that has a beta/
D-type sunspot group. Yesterday's target NOAA 13910 retains a beta-
gamma/D-type configuration and only produced a C2.2 flare in the
period. Today the target will switch to a newly numbered region
NOAA 13912, which produced six C-class flares including a C5.0.
13912 was designated as a beta/E-type configuration. Further C-class
flares are expected in the next 24 hours.
The position of NOAA 13912 on November 29 at 12:30 UT is:
S04E59 (-833", -77")

Dear Collaborators,
Solar activity continues to be at a low level. The largest event since
the last message was an M1.0 flare at 12:27 UT yesterday from
NOAA 13901 that has an alpha/H-type configuration. There were a
few C-class flares produced by various regions including the target
NOAA 13910. 13910 has developed to a beta-gamma/D-type region.
Today we will watch this region for one more day. C-class activities
are expected with some chance of a low M-class flare in the following
24 hours.
The position of NOAA 13910 on November 28 at 08:30 UT is:
N17E50 (-714", 272")

Dear Collaborators,
Solar activity was at a low level over the past 24 hours. The largest
event was a C7.4 flare at 12:32 UT yesterday produced by the limb
target region. This region has been designated as NOAA 13910 with
a beta/D-type sunspot group. It also produced four low C-class (~C3)
flares. Another region NOAA 13906 (S16E14, beta-gamma-delta/E-type)
was the source of four C-class flares (the largest one being a C5.6).
At this time, we are ending the Major Flare Watch campaign. Further
C-class activities are expected with some low M-class flares probable
in the next 24 hours.
The position of NOAA 13910 on November 27 at 08:30 UT is:
N16E64 (-841", 258")

Dear Collaborators,
Solar activity has been at a moderate level since the last message.
There occurred five low M-class flares and three of them (M2.0, M1.0,
and M1.2) were produced by NOAA 13906 that retains a beta-gamma-
delta/E-type configuration. The limb target region produced an M1.5
flare in the period and is rotating onto the visible solar disk. Today we
will watch this limb region as the Major Flare Watch target for a further
24 hours. Additional low M-class activities are expected from this region
as well as NOAA 13906 (S17E28), with some chance of a flare above
M5 in the next few days.
The approximate position of the target on November 26 at 08:30 UT is:
N20E86 (-910", 340")
