Dear Collaborators,
Solar activity was at a moderate-to-low level. The largest event during
the period was an M2.4 flare at 06:09 UT today produced by the target
region NOAA 13697. This region also produced another M1.7 flare and
a few C-class flares (including three C8 flares). NOAA 13697 retains a
beta-gamma-delta configuration, with some new emerging sunspots in
its trailing portion. Considering that its current helicity remains at a high
level, we will continue the Major Flare Watch on this region for a further
24 hours. Further C- and M-class activity is expected, with a slight chance
of an isolated >M5 flare.
The position of NOAA 13697 on 4-Jun-2024 at 15:30 UT is:
S18W16 (248",-290")

Dear Collaborators,
Solar activity has slightly diminished since the last message. The target
region NOAA 13697 remains classified as a beta-gamma-delta configuration,
with an increase in sunspot area and number of spots. This region continued
as the most flare-productive region on disk, being the source of four low
M-class flares plus more than ten C-class flares, while the largest magnitude
flare was an M4.8 at 13:58 UT today from NOAA 13695 (N27W42, beta/C-type).
The Major Flare Watch will continue with NOAA 13697 as the target region
due to its magnetic complexity, ongoing flux emergence, and prior
flaring history.
Additional M-class flares are expected from these two regions, with a chance
for major (>M5) flares in the next 24-48 hours.
The position of NOAA 13697 on 3-Jun-2024 at 15:30 UT is:

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. NOAA 13697 produced over 15 flares, including an X1.0 at
18:24 UT yesterday. The Major Flare Watch will continue as this region
shows signs of dynamic sunspot behaviour and complexity. Additional
M-class activity is expected, with a chance for an isolated >M5 event
in the next 24 hours.
The position of NOAA 13697 on 02-June-2024 at 07:30 UT is:

Dear Collaborators,
Solar activity has partially increased since the last message. NOAA
13697 produced two X-class flares, the largest being an X1.4 at 08:26
UT today. This region remains classified as a beta-gamma-delta and
shows signs of significant flux. The Major Flare Watch will continue
with NOAA 13697 as the target region. Additional >M5 activity is
possible in the next 24-48 hours.
The position of NOAA 13697 on 01-June-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has slightly diminished since the last message. A
number of flares were produced in the last 24 hours, the largest being
an M1.0 at 11:06 UT today from NOAA 13697. This region continues to
show signs of emerging flux and some limited signs of dynamic sunspot
behaviour. The Major Flare Watch will be extended for a further 24
hours with NOAA 13697 as the target region. Further C- and M-class
activity is expected, with a slight chance for an isolated >M5 flare.
The position of NOAA 13697 on 31-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity remains at an intermediate level. A number of flares
were produced in the last 24 hours, including an X1.4 from NOAA 13697
at 14:11 UT yesterday. Additionally, an M5.7 was produced from NOAA
13691 at 18:32 UT yesterday. NOAA 13697 is now classified as a
beta-gamma-delta type region with an approximate area of 400 μh. The
Major Flare Watch will continue with NOAA 13697 as the target region.
Additional >M5 activity is possible over the next 24-48 hours.
The position of NOAA 13697 on 30-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity continues at an intermediate level. The target region
has now been numbered as NOAA 13697 and has produced several flares in
the last 24 hours, the largest being an M2.6 at 12:45 UT today.
Currently, this region is classified as a beta-gamma type region and
continues to show signs of significant flux. The Major Flare Watch
will be extended for what may be the final 24 hours, while target
region NOAA 13697 continues to traverse further onto the solar disk.
Further C-class activity is expected with a slight chance for an
isolated >M5 event.
The position of NOAA 13697 on 29-May-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has remained at an intermediate level since the last
message. The target region produced several partially-occulted flares,
the largest being a C9.0 at 19:09 UT yesterday. The target region is
now partly visible on the southeast limb and continues to traverse
onto the solar disk, but remains unnumbered. This region also
continues to show significant flux and numerous closed loops in the
upper solar atmosphere. The Major Flare Watch will continue while the
target region moves further onto the solar disk. Isolated >M5 activity
is possible in the next 24-48 hours.
The approximate position of the target region on 28-May-2024 at 11:30 UT is:
S18E81, (-888", -290")

Dear Collaborators,
Solar activity is at a low-intermediate level. Several flares were
produced since the last message, including a partially-occulted X2.9
from a currently unnumbered region behind the southeast limb at 06:49
UT today. It is believed that this region corresponds to the
previously numbered active region NOAA 13664 rotating back onto the
disk. This region also shows significant flux emergence. At this time
we are implementing a Major Flare Watch and the target region will
switch to the southeast limb surrounding this active region as it
rotates onto the solar disk. Further >M5 activity is possible within
the next 24-48 hours.
The approximate position of the target region on 27-May-2024 at 11:30 UT is:
S18E86, (-899", -291")

Dear Collaborators,
Solar activity continues at a low level. The largest event
since the last message was a C5.3 flare at 09:27 UT today
produced by a new numbered region NOAA 13691. This
region also produced two low C-class flares. It has been
designated as a beta-gamma-delta/D-type configuration
and is showing some new flux emergence. This region will
become today's target. Yesterday's target 13685 has been
steady and did not show any notable activities. Further C-class
activities are expected from 13691, with a chance of low
M-class flares in the next 24 hours.
The position of NOAA 13691 on May 26 at 11:30 UT is:
N25E53 (-686", 412")
