Dear Collaborators,
Solar activity has been at a high level since the last message.
The target region NOAA 13738 produced an X1.5 flare an hour
ago (at 02:23 UT) and also six M-class flares (including an M5.3
at 12:21 UT and an M5.0 at 22:44 UT yesterday). 13738 has
been designated as a beta-gamma-delta/F-type configuration
with a sunspot area of 1100 MSH. At this time we implement
the Major Flare Watch campaign on this region. Additional M-
class activities are expected with a good chance of >M5 flare
in the next 24 hours.
The approximate position of NOAA 13738 on July 14 at 00:00 UT is:
S09W40 (600", -200")

Dear Collaborators,
Solar activity has been at a moderate level since the last message.
The target region NOAA 13738 produced the largest magnitude flare,
an M1.4 at 02:55 UT today. It also produced five C-class flares including
a C9.6. This region retains a beta-gamma/F-type configuration with
increasing the sunspot area further. Note that a southeast limb region
(S08E89) produced two occulted C8.0 flares. Additional C-class activities
are expected with a good chance of some low M-class flares in the next
24-48 hours.
The position of NOAA 13738 on July 13 at 11:30 UT is:
S09W33 (509", -205")

Dear Collaborators,
Solar activity was at a low level in the past 24 hours. The
largest event was a C6.5 flare peaking at 13:28 UT today
produced by the target region NOAA 13738 (and also 13743?).
13738 retains a beta-gamma/F-type configuration and produced
more than ten C-class flares. Further C-class activities are
expected with some chance of a low M-class flare in the next
24 hours.
The position of NOAA 13738 on July 12 at 15:30 UT is:
S08W22 (351", -193")

Dear Collaborators,
Solar activity was at a moderate level in the past 24 hours. The largest
event since the last message was an M1.3 flare at 04:03 UT produced
by a newly numbered region NOAA 13745 (S17E51, beta/C-type). The
target region produced two M1 flares (M1.0 and M1.2) and more than
10 C-class flares (including a C9.7) during the period. 13738 has been
designated as a beta-gamma/F-type configuration with increasing in the
sunspot area and number of spots significantly. Additional low M-class
flares are expected in the next 24 hours.
The position of NOAA 13738 on July 11 at 11:30 UT is:
S10W06 (97", -228")

Dear Collaborators,
Solar activity has been at a moderate level since the last message.
NOAA 13738 produced four M-class flares (M1.5, M1.3, M1.4, and
M1.2) and 10 C-class flares today. This region retains a beta-gamma/
E-type configuration but increases the number of spots significantly.
Today the target will switch back to this region. Yesterday's limb target
was designated as NOAA 13742 and only produced a C3.0 flare during
the period. Further C-class activities are expected with a good chance
of low M-class flares in the next 24 hours.
The position of NOAA 13738 on July 10 at 11:30 UT is:

Dear Collaborators,
Solar activity was at a moderate-to-low level. The largest event
since the last message was an M1.1 flare at 12:34 UT on July 8
produced by the limb target (still unnumbered yet). This limb region
also produced a few C-class flares during the period. It is rotating
onto the visible solar disk. Another three regions, NOAA 13738
(S08E23, beta-gamma/E-type), 13736 (S18W07, beta/C-type), and
13740 (S17W39, beta/B-type), produced a few C-class flares as
well. Further C-class activities are expected with a chance of low
M-class flare in the next 24 hours.
The approximate position of the target on July 9 at 11:30 UT is:
S20E80 (-875", -350")

Dear Collaborators,
Solar activity was at a moderate level. The largest event since the
last message was an M2.5 flare at 22:03 UT on July 7 produced by
a southeast limb region. This limb region also produced three ~M1
and a few ~C5 flares during the period. Today the target will switch
to this limb region due to its high flare activity although it is still beyond
the east limb mostly. Please note that yesterday's target NOAA 13738
(S09E40) retains a beta-gamma/E-type configuration and produced an
M1.0 flare at 23:19 UT on July 7. More C-class activities are expected
with a good chance of additional M-class flares from the new target
and also NOAA 13738 in the next 24 hours.
The approximate position of the target on July 8 at 07:30 UT is:
S24E87 (-900", -400")

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region NOAA
13729 has now rotated up to the South West limb and although it
was classified as an alpha/H-type sunspot group this designation
will be hampered by foreshortening effects. This region produced
only one flare in the period, a C7.2 on 7-Jul-2024 at 01:56 UT.
NOAA 13738 (a beta-gamma/E-type group) has grown in sunspot area
and number of spots since the last message to become the most
magnetically complex region on the disk. NOAA 13738 has been the
most flare-productive region in the period with 6 C-class flares
and the only M-class flare - an M1.0 on 6-Jul-2024 at 22:52 UT.
NOAA 13738 becomes the new target region. More C-class activity
is expected in the next 24 hours, with a good chance for more
M-class activity.
The position of NOAA 13738 on 7-Jul-2024 at 15:30 UT is:
S09E49 , ( -705", -186" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA
13737 has now rotated up to the South West limb so its
magnetic classification is unable to be determined. This
region produced 4 C-class flares, including the largest
magnitude flare in the period - a C9.4 on 5-Jul-2024 at
18:47 UT. NOAA 13729 (a beta-gamma/E-type sunspot group)
is the most magnetically complex region on the disk and
increased in flare productivity through the period along
with generating the second largest magnitude flare - a
C8.6 on 5-Jul-2024 at 20:03 UT. NOAA 13737 will soon
rotate out of Earth-view, so NOAA 13729 becomes the new
target. Further C-class activity is expected over the
following 24-hour period, with a good chance for a low
M-class flare.
The position of NOAA 13729 on 6-Jul-2024 at 15:30 UT is:
S04W61 , ( 824", -93" )

Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region
NOAA 13730 was the source of the largest magnitude flare in
the period - an M1.4 on 4-Jul-2024 at 19:54 UT. After this
NOAA 13730 decayed to the point of losing all its spots to
become an unnumbered plage region. NOAA 13733 increased
quite significantly in sunspot area since the last message,
but remained classified as a beta/D-type sunspot group and
only produced one C-class flare (a C3.5 on 4-Jul-2024 at
17:59 UT). Newly numbered NOAA 13737 (a beta/D-type spot
group) was the most flare-productive region with generating
four C-class flares, the largest of which being a C4.1 on
5-Jul-2024 at 15:06 UT. NOAA 13737 becomes the new target
for the next 24 hours while it rotates up to the South West
limb. Additional C-class flares are expected in the next
24 hours, with a chance for further low M-class activity.
The position of NOAA 13737 on 5-Jul-2024 at 15:30 UT is:
S14W85 , ( 911", -232" )
