Dear Collaborators,
Solar activity has slightly increased since the last message. The largest
event in the period was a C5.2 flare at 04:31 UT today from NOAA 13538
(N21W19), but this region has been downgraded from a beta-gamma to
a beta configuration. Two southeastern limb regions have been numbered
as NOAA 13540 and 13541, which has remained active during the period,
being the source of several low C-class flares. The target region NOAA
13536 retains its beta-gamma magnetic configuration and also produced
a few low-to-mid C-class flares in the period. 13536 shall continue as the
default target region due to its magnetic complexity and its past flaring
history. Additional C-class flares are expected in the next 24 hours, with
a slight chance for an isolated low M-class flare.
The position of NOAA 13536 on 6-Jan-2024 at 08:30 UT is:
N06E06, (-101",162")

Dear Collaborators,
Solar activity has dropped to low levels since the last message.
The largest event in the period was a C3.7 flare at 07:55 UT today,
attributed to NOAA 13534 (S15W56, beta/D-type). However, some
other flares from the target region NOAA 13536 and a southeastern
limb region (S20E88) also contributed to the soft X-ray flux. 13536
retains its beta-gamma magnetic configuration and produced three
low C-class flares in the period, while the southeastern limb region
was the source of six low C-class flares. Regions NOAA 13537 and
13538, nearby the target NOAA 13536, have now developed to a
beta-gamma configuration. At this time we are ending the Major
Flare Watch campaign and NOAA 13536 will remain as the target
region due to its continued flux emergence and the magnetic
complexity of it and its neighboring regions. Further C-class activity
is likely, with a slight chance of M-class flares.
The position of NOAA 13536 on 5-Jan-2024 at 08:30 UT is:

Dear Collaborators,
Solar activity has slightly increased since the last message. The largest
event in the period was an M3.9 flare at 01:22 UT today from the target
region NOAA 13536, which also produced several C-class flares. 13536
retains its beta-gamma magnetic configuration with fresh flux emergence
and shall continue as the target region. The Major Flare Watch shall
remain in effect for a further 24 hours due to the possibility of an >M5 flare.
The position of NOAA 13536 on 4-Jan-2024 at 12:30 UT is:
N06E30, (-486",151")

Dear Collaborators,
Solar activity has slightly diminished since the last message.
The target region NOAA 13536 continued to be the most
flare-productive region on the visible disk, being the source
of several low C-class flares as well as the largest magnitude
event in the period - an M1.2 at 18:02 UT yesterday. 13536
is now classified as a beta-gamma region and is showing
signs of additional flux emergence along its northern edge.
The Major Flare Watch will be extended for a further 24 hours,
with a slight chance for an isolated >M5 flare.

Dear Collaborators,
Solar activity is at a high level. The largest event in the period was an
M4.7 flare at 11:54 UT yesterday from the target region NOAA 13536,
which also produced over ten C-class flares and has now developed
into a beta-delta region. The Major Flare Watch will continue for this
region due to its high current helicity and magnetic complexity. More
C-class activities are expected, with a good chance of additional
M-class flares.
The position of NOAA 13536 on 2-Jan-2024 at 08:30 UT is:

Dear Collaborators,
Solar activity has been at an intermediate level since the last message.
The target region nearby the northeast limb has been numbered as
NOAA 13536 with an alpha/H-type magnetic configuration. 13536
continued to be the most flare-productive region on the visible disk,
being the source of several low-to-mid C-class flares as well as the
largest magnitude event in the period - an M2.4 at 08:33 UT today.
The Major Flare Watch shall remain in effect with NOAA 13536 as
the target region. Additional low M-class flares are expected with
a chance of another >M5 flare in the next few days.
The position of NOAA 13536 on 1-Jan-2024 at 08:30 UT is:
N05E70 (-914",102")

Dear Collaborators,
The target region on the northeast limb has produced an X5 flare at
21:36 UT today. As such we are implementing a Major Flare Watch at
this time. Chance for additional >M5 flares over the next 24-48 hours.
The approximate position of the target region on 31-Dec-2023 at 20:30 UT is:
N04E79, ( -957", 77" )

Dear Collaborators,
Solar activity is at the C-level. NOAA 13530/NOAA 13533 produced a few
low level events since the last message as they rotated out of view on
the western limb. A new region approaching on the eastern limb was the
source of two partially occulted high C-class flares today. The region
is not yet numbered and its magnetic configuration is uncertain at
this time, but it shall be the new target region. Further C-level
activity likely with chance for an isolated low M-class flare in the
next 24 hours.
The approximate position of the target region on 31-Dec-2023 at 08:30 UT is:
N04E89, ( -973", 69" )

Dear Collaborators,
Solar activity continues at low levels. NOAA 13533 has remained
quiescent but nearby active region NOAA 13530, now on the northeast
limb, was the source of several C-class flares since the last message,
including a C6.6 flare at 20:07 UT yesterday. NOAA 13533 has shown
signs of decay but shall continue as the target region with isolated
low-level events possible. Also include NOAA 13530 in your field of
view as it rotates over the limb.
The position of NOAA 13533 on 30-Dec-2023 at 08:30 UT is:
N14W59, ( 812", 259" )

Dear Collaborators,
NOAA 13529 is now beyond the southwest limb. There has been an
increase in activity due to the emergence of a new beta region in the
northwest quadrant. The region numbered as NOAA 13533 produced several
C-class flares since the last message, including a C9.8 flare at 07:49
UT today. NOAA 13533 shall be the new target region and may produce
further C-level activity over the next 24 hours.
The position of NOAA 13533 on 29-Dec-2023 at 16:30 UT is:
N14W46, ( 682", 267" )
