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")

Dear Collaborators,
There was just an M9.4 flare (at 07:24 UT) produced by a region
beyond the northeast limb mostly. At this time, we are implementing
the Major Flare Watch campaign on this limb region. This region
also produced an M1.1 flare at 20:11 UT yesterday. Also note that
yesterday's target NOAA 13906 (S16E42) has developed to a beta-
gamma-delta/E-type region with a sunspot area of ~500 MSH and
was the source of two M-class (M1.1 and M1.8) and five C-class
flares since the last message. Further C- and low M-class activities
are expected with a good chance of another major flare (>M5) in the
next few days.
The approximate position of the target on November 25 at 08:30 UT is:
N20E89 (-940", 325")

Dear Collaborators,
Solar activity remains at a moderate level. Yesterday's target NOAA
13905 (S09E46, beta-gamma/E-type) has been flare-quiet since the
last message, while nearby NOAA 13906 (S16E52, beta-gamma/D-
type) has become active. 13906 was the source of eight mid-C-class
flares in the period and now appears to be undergoing flux emergence
in its trailing sunspot. Today the target shall switch to NOAA 13906,
but if possible, please include NOAA 13905 in your field of view as well.
The largest event in the period was an M1.2 flare from NOAA 13901
(S07W14, beta-gamma/C-type) at 15:54 UT yesterday (11/23).
Additionally, a northeast region (N11E70, unnumbered yet) also
produced an M1.1 flare and several C-class flares in the period.
Further low M-class flares are expected in the next 24-hour period.
The position of NOAA 13906 on 24-Nov-2024 at 12:30 UT is:
S16E52 (-737",-285")

Dear Collaborators,
Solar activity has returned to a moderate level. The largest event
since the last message was an M1.6 flare at 15:42 UT yesterday
(11/22), produced by the target region NOAA 13905 (S09E59).
This region has increased in magnetic complexity to a beta-gamma
type and produced another four C-class flares in the period. NOAA
13905 will remain the target today, as it is showing mixed polarities
in the intermediate portion. Please note that NOAA 13906 (S16E68,
beta/D-type), located near the target region, produced an M1.1 flare
and three C-class flares in the period. If possible, please also include
13906 in your field of view. Further low M-class flares are expected
in the next 24-hour period.
The position of NOAA 13905 on 23-Nov-2024 at 08:30 UT is:
S09E59 (-824",-167")

Dear Collaborators,
Solar activity is at a moderate-to-low level. The largest event since the
last message was a C9.1 flare at 03:23 UT today (11/22), produced by
the target region 13901 (S07E14). It remains classified as a beta-gamma
/D-type sunspot group and produced another two C-class flares in the
period. However, its spot activity appears relatively stable. Please note
that a limb region NOAA 13905 (S09E71, beta/D-type) also produced
two mid-C-class flares in the period and now exhibits relatively high
current helicity. Today, the target region shall switch to NOAA 13905.
Further C-class activity is expected, with a chance of low M-class flares
in the next 24 hours.
The position of NOAA 13905 on 22-Nov-2024 at 12:30 UT is:
S09E71 (-908",-162")

Dear Collaborators,
Solar activity has returned to a moderate level. The largest event
since the last message was an M1.2 flare at 19:11 UT yesterday
(11/20), produced by NOAA 13889, which has completely rotated
over the west limb. The regions NOAA 13892 and 13897, which
have also rotated over the west limb, were the sources of several
C-class flares. The target region NOAA 13901 (S07E28) retains a
beta-gamma magnetic configuration and produced three C-class
flares in the period. At this time, we are ending the Major Flare
Watch, but NOAA 13901 shall remain the target region as it is
emerging new magnetic flux in its trailing portion. Further C-class
activity is expected, with a chance of low M-class flares in the next
24 hours.
The position of NOAA 13901 on 21-Nov-2024 at 12:30 UT is:
S07E28 (-454",-149")
