Dear Collaborators,
The level of solar activity is moderate. Yesterday's target region has
now been designated as NOAA 13723, and was classified as a beta/D-type
sunspot group. This region was still located significantly towards the
East limb at the start of the UT day, so this classification might not
be totally accurate. NOAA 13723 produced two C-class flares since the
last message, with some low M-class activity produced by NOAA regions
13712 (beyond the South West limb) and 13713 (at the South West limb).
The MM#003 Major Flare Watch will continue for another 24 hours with
NOAA 13723 as the target while its development is tracked. Additional
high C-class flares are expected over the following 24-hour period,
with a chance for another M-class flare.
The position of NOAA 13723 on 24-Jun-2024 at 15:30 UT is:
S18E58 , ( -762", -310" )

Dear Collaborators,
Solar activity has increased significantly since the last message.
The largest event was an M9.3 flare at 12:51 UT today produced
by a southeast limb region (unnumbered yet). At this time we are
implementing the Major Flare Watch campaign on this limb region
that is rotating onto the visible solar disk. It should be mentioned
that NOAA 13712 and 13716 produced an M1.3 and an M2.4 flare
respectively in the period, both of which are rotating over the west
limb. Additional low M-class activities are expected with a chance
of an isolated >M5 flare in the next 24 hours.
The approximate position of the target on June 23 at 15:30 UT is:
S19E75 (-900", -300")

Dear Collaborators,
Solar activity was at a moderate level in the past 24 hours.
The largest event was an M2.9 flare at 08:43 UT on June 22
produced by NOAA 13716 (N10W73) that has a beta-gamma/
E-type configuration. NOAA 13720 (S05E35, beta/C-type) and
a southeast limb region (S19E89) also produced two ~M1.0 flares.
The target regions of NOAA 13713 (beta-gamma-delta/E-type)
and 13712 (beta-gamma) produced five high C-class flares during
the period. Today we continue to watch these two regions for a
final 24 hours as they rotate over the west limb. C-class activities
are expected with a chance of a low M-class flare in the next 24
hours probably from various regions.
The position of NOAA 13713 on June 22 at 23:30 UT is:
S14W67 (844", -240")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since the last
message. The largest event during the period was an M5.8 flare
at 23:00 UT on June 20 produced by NOAA 13719 (S13E41) that
has a beta/D-type sunspot group. This region then was flare quiet.
Yesterday's target(s) NOAA 13712 (and 13713) produced about
nine C-class flares. 13712 and 13713 retained a beta-gamma-delta/
E-type configuration but 13712 began to decay. Today we will watch
NOAA 13713 but please also include 13712 (S24W66) in the field
of view if possible. C-class activities are expected with some chance
of an M-class flare in the next 24 hours.
The position of NOAA 13713 on June 21 at 23:30 UT is:
S14W53 (733", -246")

Dear Collaborators,
Solar activity was at a moderate level in the past 24 hours.
The largest event was an M1.1 flare at 15:09 UT today produced
by NOAA 13719 (S12E56) that has a beta/C-type configuration.
13719 and some other regions, 13716 (N10W44, beta-gamma/
D-type) and 13720 (S04E65, beta/D-type), also produced a few
C-class flares. The target region(s) 13712 (and 13713) only
produced two C-class flares during the period. Both 13712 and
13713 (S15W39) have a beta-gamma-delta/E-type configuration.
Today we continue to watch 13712 and also 13713 if possible.
C-class activities are expected with a chance of low M-class flare
in the next 24 hours.
The position of NOAA 13712 on June 20 at 19:30 UT is:
S24W50 (662", -401")

Dear Collaborators,
Solar activity has been at a moderate-to-low level since the
last message. The largest event in the past 24 hours was an
M1.2 flare at 06:15 UT today produced by NOAA 13711 that
has a beta/B-type configuration and is now located near the
west limb (S11W79). Another two regions, NOAA 13713
(S16W25, beta-gamma/E-type) and 13716 (N10W31, beta-gamma/
D-type), produced four low C-class flares (two from each).
The target region NOAA 13712 retains a beta-gamma-delta/
E-type configuration but did not show any notable activity in the
period. At this moment, we end the Major Flare Watch campaign
but continue to watch NOAA 13712. If possible, please also
include NOAA 13713 in your field of view. Low M-class activities
are likely from these three regions in the next 24 hours.
The position of NOAA 13712 on June 19 at 19:30 UT is:
S26W37 (512", -434")

Dear Collaborators,
Solar activity continues at a moderate level. The target region
NOAA 13712 produced two M-class flares (an M2.4 at 11:14 UT
and an M1.2 at 12:11 UT today) and more than ten C-class flares.
It retains a beta-gamma-delta/E-type configuration with increasing
the sunspot area (to 1100 μh) and number of spots slightly. We
will continue the Major Flare Watch campaign on this region. Low
M-class activity is expected with a chance of a >M5 flare in the
next 1-2 days.

Dear Collaborators,
Solar activity has been at moderate levels since the last message.
The target region NOAA 13712 produced two M1.6 flares today (at
07:54 and 10:42 UT, with the largest magnitude) and more than ten
C-class flares. Note that another region NOAA 13711 (S11W54,
alpha/D-type) also produced an M1.4 flare at 19:57 UT today. The
target NOAA 13712 maintains a beta-gamma-delta/E-type configuration
and continues showing new magnetic flux emergence. The Major
Flare Watch campaign will continue, with M-class activities expected
and a good chance of a >M5 flare in the next few days.

Dear Collaborators,
Solar activity is at a moderate-to-low level. The target NOAA 13712
(S25E03) continued to be the most flaring region on disk, being the
source of more than twenty C-class flares, including the largest
magnitude in the period - a C7.2 flare on 15-Jun-2024 at 23:15 UT.
13712 remains a beta-gamma-delta configuration with an approximate
area of 850 μH. This region continues to show signs of emerging flux
and dynamic sunspot behaviour. Today, we will continue the Major
Flare Watch campaign on NOAA 13712 due to the possibility of an
isolated >M5 flare in the next 24–48 hours.
The position of NOAA 13712 on 16-Jun-2024 at 19:30 UT is:
S25E03 (-44",-419")

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The target NOAA 13712 (S24E16) remains the most flare-productive
region on disk, being the source of approximately thirty C-class flares
and the largest magnitude flare in the period - an M1.3 at 06:00 UT today.
13712 has now developed into a beta-gamma-delta region, with an
increase in sunspot area and number of spots. This region continues to
show signs of emerging flux and dynamic sunspot behaviour in its
intermediate portion. At this time, we are implementing a Major Flare
Watch campaign on NOAA 13712 due to the possibility of an isolated
>M5 flare.
The position of NOAA 13712 on 15-Jun-2024 at 15:30 UT is:
S24E16 (-238",-401")
