Dear Collaborators,
Solar activity is at a moderate-to-low level. Yesterday's target region
NOAA 13713 (S13E45, beta/D-type) produced three C-class flares
since the last message. The largest event in the period was an M2.4
flare at 04:14 UT today from the nearby region NOAA 13712 (S24E29)
mentioned in the previous message. 13712 was the most flare-productive
region in the period, which also produced another more than ten C-class
flares and has developed into a beta-gamma region. This region continues
to undergo flux emergence and is showing mixed polarities in the intermediate
portion. Today the target shall switch to NOAA 13712. Further C-class activity
is expected, with a chance for an isolated low M-class flare.
The position of NOAA 13712 on 14-Jun-2024 at 15:30 UT is:
S24E29 (-419",-398")

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The target region has now been numbered as NOAA 13713 (S13E59,
beta/D-type) and produced the largest event during the period - an M3.2
flare at 16:34 UT today. This region and a nearby region NOAA 13712
(S24E43, beta/D-type) also produced several C-class flares in the period.
The default target will remain as NOAA 13713 due to the continued flux
emergence in its intermediate portion. If possible, please also include
the nearby region 13712 in the field of view, which is showing significant
magnetic flux emergence as well. Please note that NOAA 13711 (S09E03,
beta/B-type) also produced an M1.2 flare in the period. Further C-class
activity is expected, with a good chance for additional low M-class flares.
The position of NOAA 13713 on 13-Jun-2024 at 15:30 UT is:
S13E59 (-790",-220")

Dear Collaborators,
Solar activity is at a low level. Yesterday's target NOAA 13697 has
nearly rotated beyond the west limb. The largest event since the
last message was a C4.4 flare at 12:53 UT today from a southeast
limb region (S09E79, unnumbered yet). This region also produced
a C2.5 flare in the period. Two nearby active regions, NOAA 13711
(S08E16, beta/D-type) and NOAA 13709 (S09E04, beta/D-type),
also produced several low C-class flares in the period, but these
two regions have shown a decay in the sunspot area. At this moment,
we shall end the Major Flare Watch campaign and the target region
will switch to the southeast limb region. C-class activities are expected
in the next 24 hours.
The approximate position of the target region on 12-Jun-2024 15:30 UT is:
S09E79 (-916",-150")

Dear Collaborators,
Solar activity is at a moderate-to-low level. Target region NOAA 13697
has now rotated over the South West limb, with some overlying loops
visible above the limb. This region produced numerous C-class flares
and the largest magnitude flare in the period - an M9.6 on 10-Jun-2024
at 18:11 UT. The Major Flare Watch shall remain in effect with NOAA
13697 for a final 24 hours, as it rotates fully out of view beyond the
South West limb. Further C-class activity is expected, with a slight
chance for an isolated low M-class flare.
The position of NOAA 13697 on 11-Jun-2024 at 15:30 UT is:
S19W91 (892",-307")

Dear Collaborators,
Solar activity has increased to a high level since the last message.
The largest event was an X1.6 flare at 11:03 UT, happening just now,
produced by the target region NOAA 13697 (S19W91). This region
also produced another four M-class flares (M1.0, M3.3, M2.3, and
M5.3) and several C-class flares during the period. Today we will
continue the Major Flare Watch campaign on NOAA 13697 before
it completely rotates over the west limb. Further C- and M-class
activity is expected, with a chance for additional >M5 flares.

Dear Collaborators,
Solar activity has decreased to a moderate level since the last message.
Target region NOAA 13697 remains a beta-gamma-delta configuration
and produced the vast majority of flare activity during the period, being
the source of more than ten C-class flares and the largest magnitude
flare in the period - an M1.7 on 9-Jun-2024 at 06:49 UT. Additionally,
NOAA 13709 (S10E51, beta/C-type) and NOAA 13703 (S08W61, beta-
gamma/D-type) each produced an ~M1.0 flare in the period. Today we
will continue the Major Flare Watch campaign on NOAA 13697 as it
rotates to the west limb. If possible, please also include the nearby region
13703 in the field of view. Further C- and M-class activity is expected,
with a chance for an isolated >M5 flare.

Dear Collaborators,
Solar activity has increased to a high level since the last message.
The largest event in the period was an M9.8 flare at 01:23 UT today
from the target region NOAA 13697. This region remains classified
as a beta-gamma-delta configuration and also produced another
three low M-class flares plus nine C-class flares during the period.
Today we continue the Major Flare Watch on this region due to the
continued flux emergence in its intermediate portion. Please note
that the southeast limb region, mentioned in the two previous messages,
has been numbered as NOAA 13709 (S10E67, beta/C-type) and
has produced four ~M1.0 flares during the period. Further M-class
flares are expected, with a chance of an X-class flare in the next
24–48 hours.
The position of NOAA 13697 on 8-Jun-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity is at a moderate level. The target region NOAA 13697
has produced an M1.3 flare and nine mid-to-high C-class flares in
the last 24 hours. 13697 remains a beta-gamma-delta configuration
and continues to undergo flux emergence in its trailing portion. The
largest magnitude flare in the period was an M4.1 at 08:52 UT today
from the southeast limb region (S10E89) mentioned in the previous
message. This limb region also produced another two C5.8 flares
during the period. However, the Major Flare Watch will remain with
NOAA 13697 due to its magnetic complexity, high current helicity,
and past flaring history.
The position of NOAA 13697 on 7-Jun-2024 at 15:30 UT is:
S17W55 (741",-278")

Dear Collaborators,
Solar activity has slightly increased since the last message.
The largest event during the period was an M6.1 flare at
14:50 UT today, produced by the target region NOAA 13697.
13697 remains classified as a beta-gamma-delta configuration
and was also the source of six C-class flares, including two
~C8 flares. The Major Flare Watch will continue with NOAA
13697 as the target region, due to its magnetic complexity
and continued flux emergence. Please note that a southeast
limb region (S10E89) also produced a C9.5 flare in the period.
Additional >M5 activity is possible in the next 24-48 hours.
The position of NOAA 13697 on 6-Jun-2024 at 15:30 UT is:
S18W42 (603",-293")

Dear Collaborators,
Solar activity continues at a moderate-to-low level. The largest event
during the period was an M3.5 flare at 08:32 UT today produced by
the target region NOAA 13697. This region was also the source of
another M2.6 flare and two low C-class flares. 13697 retains a
beta-gamma-delta configuration, but decreases in the sunspot area.
The Major Flare Watch will be extended for a further 24 hours with
NOAA 13697 as the target region, due to its magnetic complexity
and continued flux emergence. Further C- and M-class activity is
expected, with a slight chance for an isolated >M5 flare.
