Dear Collaborators,
Solar activity continues at a low level. The largest flare produced in the
last 24 hours was a C3.1 from NOAA 14446 at 01:59 UT today. The active
region eastward of the target region continues its transition onto the disk
and appears to show significant flux. The target region, NOAA 14455, has
been relatively quiet since the last message. In general activity across
the disk remains low. As the region beyond the northeastern limb continues
to progress onto the disk, NOAA 14455 will continue as the target region.
Further C-class activity is expected.
The position of NOAA 14455 on 31-May-2026 at 07:30 UT is:
N15E34, (-512", 256")

Dear Collaborators,
Solar activity is at a low level. Several flares have been produced since
the last message, the largest being a C4.8 from NOAA 14444 at 11:45 UT
today. NOAA 14455 appears to be fully progressed onto the disk, however a
bright region still remains beyond the northeastern limb, which may produce
further occulted activity. Elsewhere, sunspot activity appears steady
across the disk. Further C-class activity is expected in the next 24 hours.
The position of NOAA 14455 on 30-May-2026 at 11:30 UT is:
N15E44, (-636", 255")

Dear Collaborators,
Solar activity persists at a low level. The largest flare of the last 24
hours was an M1.2 from NOAA 14455 at 06:40 UT today. NOAA 14455 is now
classified as a beta type region. This region continues to show a
significant level of flux and there appears to be a further connected
portion yet to transit onto the disk. NOAA 14455 will remain the target
region. Further C-class activity is expected with further chance for
isolated low M-class events.
The position of NOAA 14455 on 29-May-2026 at 11:30 UT is:
N15E58, (-776", 253")

Dear Collaborators,
Solar activity remains at a low level. The target region is now numbered as
NOAA 14455 and produced the largest flare since the last message, which was
a C2.9 at 13:19 UT yesterday. Currently, NOAA 14455 is classified as an
alpha-type region with a sunspot area of ~ 450 μh, however this may change
as the region progresses further into view. NOAA 14455 will continue as the
target region with further C-class activity expected.
The position of NOAA 14455 on 28-May-2026 at 11:30 UT is:
N14E71, (-869", 235")

Dear Collaborators,
Solar activity has slightly diminished. The largest flare produced since
the last message was a C4.7 from NOAA 14451 at 23:39 UT yesterday. The
target region continues to produce further occulted flares and appears to
be rotating over the solar limb onto the disk. As of this time, this region
remains unclassified but this may change in the next 24-48 hours. The
target region will remain as the active region at the northeastern limb.
Further C-class activity is expected.
The approximate position of the target region on 27-May-2026 at 11:30 UT is:
N17E84, (-900", 279")

Dear Collaborators,
Solar activity continues at a low level. A small number of flares have been
produced since the last message, the largest being a C9.7 from NOAA 14451
at 12:30 UT today. The target region over the northeastern limb still
appears to be substantial but has not yet rotated onto the disk. This
region continues to produce occulted C-class flares. This region will
continue as the target region, however attention should also be paid to
NOAA 14451 as this region may produce additional high C-class events.
Further C-class activity is expected in the next 24 hours.
The approximate position of the target region on 26-May-2026 at 15:30 UT is:
N12E89, (-918", 200")

Dear Collaborators,
Solar activity is at a low level. Several flares were produced in the last
24 hours, the largest being a C4.6 from an unnumbered active region over
the northeastern limb at 22:33 UT on the 25/05/26. This region shows a
significant level of flux despite not yet being fully visible on the disk
and was also the site of a number of other occulted C-class events. The
target region will switch to the northeastern limb about this active
region. Further C-class activity is expected with the chance for some
additional occulted high C-class/low M-class events.
The approximate position of the target region on 26-May-2026 at 03:30 UT is:
N12E22, (-442", 217")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since the last
message. Yesterday's target region rotated from the Southeast limb
was designated as NOAA 14446. This region has produced more than 10
low-to-mid C class flares in the last 24 hours, with the largest
being a C5.6 flare at 21:57 UT yesterday(5/23). Currently at least 3
sunspots with the leading(negative) polarity are visible from the
Earth, which appear to be the leading portion of a larger region.
A series of flares were produced from the Northeastern area of the
currently visible sunspots of NOAA 14446, but this area has somewhat
calmed down in the recent 12 hours. The latest flares in these several
hours are 2 low-C class events from NOAA 14441 approaching the West
limb.
Today we will continue to observe NOAA 14446, but the target is
shifted to the Northeast area of this region, because of the flare
history since yesterday.
The position of the target on 24-May-2026 at 16:00 UT is:
S07E72 (-894", -110").

Dear Collaborators,
Solar activity has declined to a low-to-moderate level since the last
message. The main source of flare activity has been an unnumbered
region rotated from the Southeast limb. This region produced 10 low-C
class flares in the past 24 hours, with the largest being a C3.6 flare
at 5:35 UT today(5/23). The target region, NOAA 14441 also contributed
to this C3.6 event, but no other flare activity was reported.
Today we will switch the target to this unnumbered region from the
Southeast limb. Currently only one moderate-sized sunspot is visible
from us close to the limb, and the flares are coming from further
close to the limb. We will therefore observe the East side of the
currently visible sunspot, expecting additional C-class events.
The position of the target on 23-May-2026 at 15:00 UT is:
S14E79 (-903", -225").

Dear Collaborators,
Solar activity during the last 24 hours was elevated to a moderate
level due to the flares from behind the Northwestern limb produced
by NOAA 14436. This region produced more than 10 flares larger than
high-B class, with the largest being an M2.4 flare at 10:03 UT
today(5/22). The loop system over NOAA 14436 will be fully out of our
view in the next 24 hours.
Yesterday's target, NOAA 14441 added new sunspots in the Northeast
vicinity of the leading sunspots, now being classified as a beta-gamma
type. Today we will continue to observe NOAA 14441 in the area of
the new flux emergence, the source of a C1.5 flare today at 12:55 UT.
The position of the target in NOAA 14441 on 22-May-2026
at 15:30 UT is: N09W53 (749", 180").
