Dear Collaborators,
Solar activity has returned to a high level since the last message.
Just at 11:29 UT, an X1.2 flare was produced by NOAA 13947
(N10E66), a northeast region previously mentioned. This region
also produced six C-class flares during the period. At this time,
we are implementing the Major Flare Watch campaign on NOAA
13947. Besides, yesterday's target NOAA 13936 has fully rotated
beyond the west limb, which also produced an M1.1 and two
C-class flares in the period. Further C- and low M-class activities
are expected, with a good chance of additional major flares (>M5)
in the next few days.
The position of NOAA 13947 on 3-Jan-2025 at 08:30 UT is:
N10E66 (-878",191")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since
the last message. The largest event was an M1.2 flare
at 18:05 UT yesterday, produced by the target region
NOAA 13936 (N13W89). It has nearly rotated beyond
the west limb and also produced an M1.1 flare and two
mid-to-high C-class flares in the period. We will watch
this region for a final 24 hours but are ending the Major
Flare Watch campaign at this time. Additionally, the
northeast limb region (N10E82), mentioned in yesterday's
message, produced three mid-to-high C-class flares
during the period. Further C-class activity is expected,
with a good chance for additional low-M flares in the
following 24 hours.
The position of NOAA 13936 on 2-Jan-2025 at 08:30 UT is:
N13W89 (950",219")

Dear Collaborators,
Solar activity has dropped to a moderate level since the
last message. The target region NOAA 13936 (N13W76)
was still the most flare-productive region on the visible
solar disk as it approaches the northwest limb. It produced
several C-class flares and three low M-class flares during
the period, with the largest being an M2.7 at 22:02 UT
yesterday. The Major Flare Watch shall remain in effect
with NOAA 13936. Additionally, NOAA 13938 (N19W35,
beta-gamma/D-type) produced an "M2.9" flare during the
decay phase of the M2.7 flare. A northeast limb region
(N10E89, unnumbered yet) also produced an M1.0 and
two mid-to-high C-class flares in the period. Further low-M
activity is expected, with a chance for an isolated >M5 flare
in the next 24 hours.
The position of NOAA 13936 on 1-Jan-2025 at 12:30 UT is:
N13W76 (922",231")
