Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA
13165 has now rotated over the South West limb and produced only a
single C-class flare since the last message. NOAA region 13169 has
recently rotated into view over the North East limb and was first
numbered today, receiving a beta/D-type sunspot group designation
(although it might now display a beta-gamma configuration). NOAA
13169 has been the most flare-productive region in the period with
being the source of eight C-class flares and the largest event, an
M1.0 flare on 17-Dec-2022 at 19:40 UT. The MM#003 Major Flare Watch
terminates at this point, due to NOAA 13165 rotating out of view.
The target now switches to NOAA 13169. Further C-class activity is
expected in the next 24 hours, with a chance for additional M-class
flaring.
The position of NOAA 13169 on 18-Dec-2022 at 16:00 UT is:
N20E67 , ( -845", 342" )

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13165
has been designated as a magnetically less-complex region since
the last message (now a beta/D-type sunspot group) but this will
be influenced by foreshortening effects due to its proximity to
the South West limb. This region continued to be the most flare-
productive region with being the source of eleven C-class events,
including the largest flare in the period (a C9.1 on 16-Dec-2022
at 19:02 UT). The MM#003 Major Flare Watch will remain in effect
for what will probably be a final 24 hours until NOAA 13165 has
rotated completely out of view. High C-class flares are probable
in the following 24-hour period, with a small chance for another
>= M5 flare.
The position of NOAA 13165 on 17-Dec-2022 at 18:00 UT is:
S22W85 , ( 900", -363" )

Dear Collaborators,
The level of solar activity is high. Target region NOAA 13165 has
continued to grow in spot area and magnetic complexity since the
last message to now be designated as a beta-delta/E-type sunspot
group. This region remains the most flare-productive region with
being the source of multiple M-class events, the largest being
an M5.7 on 15-Dec-2022 at 22:20 UT. The MM#003 Major Flare Watch
continues with NOAA 13165 as its target. Further M-class activity
is expected over the next 24 hours, with a good chance for more
flares >= M5.
The position of NOAA 13165 on 16-Dec-2022 at 16:30 UT is:
S19W72 , ( 877", -312" )

Dear Collaborators,
Solar activity is at a high level. Target region NOAA 13165 has
increased in magnetic complexity from yesterday to now be classed
as a beta-gamma/D-type sunspot group. This region continued to be
the most flare-productive region on disk and was the source of
several M-class events following yesterday's M6.3, the largest of
which was an M3.2 on 14-Dec-2022 at 14:54 UT. The MM#003 Major
Flare Watch will continue on NOAA 13165 because there remains a
good chance for another flare >= M5.
The position of NOAA 13165 on 15-Dec-2022 at 16:30 UT is:

Dear Collaborators,
The level of solar activity is moderate-to-high. Target region NOAA
13153 has rotated up to the North West limb since the last message,
and has produced an M1.1 flare on 14-Dec-2022 at 08:24 UT. However,
this is not the most flare-productive region in the period because
NOAA 13165 (a beta/D-type sunspot group) has been the source of six
M-class flares, including the largest magnitude flare since the last
message - an M6.3 on 14-Dec-2022 at 14:31 UT. At this point we are
initiating an MM#003 Major Flare Watch on NOAA 13165, as this shows
signs of continued flux emergence. More M-class flares are expected
over the next 24 hours, with a good chance for a flare >= M5.
The position of NOAA 13165 on 14-Dec-2022 at 15:00 UT is:
S20W46 , ( 662", -325" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13156 has
been flare-quiet since the last message and decayed slightly to
a beta/D-type sunspot classification. NOAA 13153 took over as
the most flare-productive region, but this was restricted to a
few low C-class flares. The target switches to NOAA 13153 as it
rotates up to the South West limb. Low C-class flares are still
possible in the following 24-hour period.
The position of NOAA 13153 on 13-Dec-2022 at 20:00 UT is:
S17W83 , ( 925", -284" )

Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA
13163 has grown slightly since the last message, increasing in its
Zurich classification to a beta/E-type sunspot group. This region
continued to produce C-class activity after the last message, but
the last was on 11-Dec-2022 at 16:45 UT. NOAA 13156 (a beta/D-type
sunspot group) has also been the source of several C-class flares
in the period, with these being more recent than the flares from
NOAA 13163. The NOAA 13156 activity includes the largest flare of
the period - a C3.5 on 12-Dec-2022 at 00:06 UT. The target changes
to NOAA 13156 due to its recent heightened activity. More C-class
flares are probable over the next 24 hours.
The position of NOAA 13156 on 12-Dec-2022 at 15:00 UT is:
N28W62 , ( 761", 462" )

Dear Collaborators,
Solar activity remains at intermediate levels since the last message.
The largest event was a C5.2 flare at 15:52 UT on 10-Dec-2022 produced
by the limb target, which was newly numbered as NOAA 13163 and was
classified as a beta/D-type sunspot group. This region still stays the most
productive and has produced 9 C-class flares and a B-class flare. Today
the target shall still be this region. Moreover, some other active regions
(NOAA 13161, 13158, 13153) also produced a few low C-class flares over
the period. Further C-class activities are expected from various active
regions in the following 24 hours.

Dear Collaborators,
Solar activity continues at intermediate levels since the last
message. The largest event was a C5.3 flare at 10:39 UT on
10-Dec-2022 produced by the limb target region (unnumbered
yet). This region has produced another ten C-class flares,
which is the most productive area. Today the target shall
remain this limb region. Please note that the other active
regions (NOAA 13156, 13162, 13157, 13161, 13158) also
produced a few low C-class flares during the period. Further
C-class activities are expected with a chance of a low M-class
flare in the next few days.

Dear Collaborators,
Solar activity has reached intermediate levels since the last
message. The largest event was a C6.0 flare at 13:59 UT on
09-Dec-2022 produced by an unnumbered limb region (S17E89).
This region has produced more than ten C-class flares. Today
the target shall switch to this limb region. Yesterday's target
NOAA 13153 (S17W30) only produced a C1.4 flare and a B8.9
flare though it was classified as a beta-gamma/F-type configuration.
Additional C-class activities are expected with a chance of a low
M-class flare in the next few days.
