Dear Collaborators,
NOAA 13514 has now passed beyond the northwest limb. Several flares
were produced over the last 24 hours, the largest being an occulted
M1.1 at 20:08 UT yesterday attributed to NOAA 13520 at the northwest
limb. A region of significant flux is now visible at the northeast
limb about NOAA 13526 and a number of flares have been produced in
this region since the last message. At this time we are ending the
Major Flare Watch campaign and switching the target region to the
northeast limb in proximity to NOAA 13526 for the next 24 hours.
Further C-class activity is expected.
The position of NOAA 13526 on 18-Dec-2023 at 12:30 UT is:
N15E62, (-832", 262")

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13514 produced a further twelve C-class flares since the
last message, the largest being a C8.4 at 13:19 UT yesterday. The
Major Flare Watch will be extended for a further 24 hours, with a
slight chance for a partially occulted M-class flare as NOAA 13514
continues its transit beyond the northwest limb.
The approximate position of NOAA 13514 on 17-Dec-2023 at 13:00 UT is:
N5W89, (971", 85")

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13514 produced several C-class flares, the largest being
a C5.5 at 21:12 UT yesterday. NOAA 13514 is currently classified as a
beta-gamma-delta type region. The Major Flare Watch will be extended
for a further 24 hours as NOAA 13514 begins its transit of the
northwest limb, with a slight chance for an isolated >M5 event.
The position of NOAA 13514 on 16-Dec-2023 at 12:30 UT is:
N05W75, (938", 89")

Dear Collaborators,
Solar activity has further increased since the last message. NOAA
13514 produced a number of significant flares in the last 24 hours,
the largest being an X2.8 at 16:47 UT yesterday. NOAA 13514 is now
classified as a beta-delta type region and has shown a substantial
increase in both area and number of spots. This region continues to
show dynamic sunspot behaviour. The Major Flare Watch will be extended
for a further 24 hours, with a chance for additional >M5 activity.
The position of NOAA 13514 on 15-Dec-2023 at 12:30 UT is:
N05W57, (816", 93")

Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA
13514 produced several flares over the last 24 hours, the largest
being an M5.8 at 07:11 UT today. NOAA 13514 continues to show dynamic
sunspot behaviour. At this time we are implementing a Major Flare
Watch with NOAA 13514 as the target region. Further >M5 activity
possible over the next 24-48 hours.
The position of NOAA 13514 on 14-Dec-2023 at 12:30 UT is:
N07W43, (661", 128")

Dear Collaborators,
Solar activity has continued at an intermediate level since the last
message. Several C-class flares were produced, the largest being a
C2.9 at 22:29 UT yesterday from NOAA 13514. This region has grown in
both area and sunspot number over the last 24 hours. NOAA 13514 will
continue to be the target region for a further 24 hours, with
additional C-class activity expected.
The position of NOAA 13514 on 13-Dec-2023 at 12:30 UT is:
N10W29, (466", 179")

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13511 produced one further C-class flare as it transited
the southwest limb. NOAA 13514 has shown dynamic sunspot behaviour
over the last 24 hours and has produced several C-class flares,
including a C9.1 at 03:27 UT today. At this time we are ending the
Major Flare Watch campaign. The target region will switch to NOAA
13514 for the next 24 hours. Further C-class activity likely, with a
chance for an isolated M-class flare.
The position of NOAA 13514 on 12-Dec-2023 at 12:30 UT is:
N06W15, (251", 110")

Dear Collaborators,
Solar activity has continued at a moderate level since the last
message. In the last 24 hours NOAA 13511 produced over fifteen C-class
flares, as well as an M1.4 flare at 22:37 UT yesterday. NOAA 13511 is
still classified as a beta-gamma type region as it begins its transit
over the southwest limb. The Major Flare Watch will be extended for a
further 24 hours, with a slight chance for an isolated >M5 flare.
The position of NOAA 13511 on 11-Dec-2023 at 12:30 UT is:
S23W78, (877", -379")

Dear Collaborators,
Solar activity has returned to a moderate level since the last message.
The target region NOAA 13511 continued to be the most flare-productive
spot region, being the source of more than ten C-class flares as well as
the largest magnitude event in the period - an M2.3 at 03:42 UT today.
13511 has now developed to a beta-gamma region with fresh flux
emergence and shall continue as the target region. The Major Flare
Watch will be extended for a further 24 hours, with a slight chance of
an above M5 flare.
The position of NOAA 13511 on 10-Dec-2023 at 12:30 UT is:
S22W66, (826",-363")

Dear Collaborators,
Solar activity had been moderately high since the last message.
Yesterday's target NOAA 13513 retains its beta-gamma magnetic
configuration and produced a small number of low C-class flares
in the period, while NOAA 13511 (a beta/E-type) was the source
of three M-class plus more than ten C-class flares, including the
largest in the period - an M5.4 flare at 22:57 UT yesterday. At this
time we are implementing a Major Flare Watch campaign with
NOAA 13511 as the new target region due to the complexity of
the magnetic field connection between it and the nearby active
regions (such as NOAA 13510) and its additional flux emergence.
Further low M-class activities are expected in the following 24-48
hours, with a chance for another above M5 flare.
The position of NOAA 13511 on 9-Dec-2023 at 12:30 UT is:
S22W52, (713",-364")
