Dear Collaborators,
Solar activity has been at a high level since the last message.
The largest event was an X1.3 flare at 19:01 UT yesterday,
produced by NOAA 13777 (S09W26). This region remains
classified as a beta-gamma-delta configuration but is becoming
much more fragmented. Target region NOAA 13780 (S12E10)
produced four ~M1 flares and three mid-level C-class flares in
the period. 13780 retains a beta-gamma-delta/F-type configuration
with a slight increase in sunspot area (now 1250 uh). This region
now appears some signs of spot spilt in its leading portion. Today,
the Major Flare Watch shall remain in effect with NOAA 13780
due to its overall size, magnetic complexity, and further evolution.
M-class activity is expected, with a good chance of >M5 flares
from various regions in the next 24-48 hours.
The position of NOAA 13780 on 9-Aug-2024 at 11:30 UT is:
S12E10 (-161",-297")

Dear Collaborators,
Solar activity has increased to a moderate-to-high level. The largest
event in the period was an M5.0 flare at 18:31 UT yesterday produced
by NOAA 13777 (S09W13, beta-gamma-delta/E-type). 13777 was
also the source of another three low M-class flares in the period.
Additionally, a South East limb region (S11E88) and NOAA 13781
(N13E29, beta-delta/D-type) also produced three low M-class flares.
Target region 13780 (S09E20) produced only six C-class flares in the
period, with a slight decrease in sunspot area (now 1110 uh) and an
increase in number of spots. 13780 has remained a beta-gamma-delta
configuration and high current helicity since the last message. 13780
continues to undergo a significant flux emergence across the entire
active region. Today, the Major Flare Watch shall remain in effect with
NOAA 13780, with a focus on its leading spots. Further M-class activity
is expected, with a good chance of >M5 flares from various regions in
the following 24-48 hours.
The position of NOAA 13780 on 8-Aug-2024 at 11:30 UT is:
S09E20 (-320",-244")

Dear Collaborators,
Solar activity has been at a moderate level since the last message.
Target region NOAA 13780 (S13E37) produced only two mid-level
C-class flares during the period. However, 13780 retains its beta-
gamma-delta/F-type configuration with an increasing sunspot area
(now 1220 uh) and number of spots. Considering that 13780 remains
a high current helicity and continues to undergo a significant flux
emergence in its leading portion, today we will continue the Major
Flare Watch on this region. Please note that the largest event in the
period was an M4.5 flare at 13:30 UT today produced by NOAA
13774 (S07W17, beta-gamma/E-type). 13774 was also the source
of an M1.8 flare and three mid-to-high C-class flares in the period.
Additionally, NOAA 13781 (N13E46, beta-gamma/D-type) produced
an M1.1 flare as well. M-class activities are expected with a chance
of >M5 flares from various regions in the next 24-48 hours.
The position of NOAA 13780 on 7-Aug-2024 at 11:30 UT is:
S13E37 (-556",-292")

Dear Collaborators,
Solar activity has been at a very high level since the last message.
Target region NOAA 13780 (S13E51) produced an X1.1 flare at
15:18 UT yesterday. 13780 has been designated as a beta-gamma
-delta/F-type configuration with a sunspot area of 930 uh. Today,
the Major Flare Watch shall remain in effect with NOAA 13780 due
to its magnetic complexity, high current helicity, and continued flux
emergence. Please note that limb region NOAA 13767 produced
the largest event in the period - an X1.7 flare at 13:24 UT yesterday,
but this region has now rotated over the South West limb. M-class
activities are expected, with a good chance of >M5 flares from
various regions in the next 24-48 hours.
The position of NOAA 13780 on 6-Aug-2024 at 11:30 UT is:
S13E51 (-717",-274”)

Dear Collaborators,
Solar activity remains at a high level. Yesterday's limb target region
has been quiescent since the last message. The largest event in the
period was an M6.1 flare at 05:13 UT today from the leading portion
of NOAA 13780 (S10E64, beta/D-type). 13780 was the most
flare-productive region in the period with generating another three
low M-class plus four C-class flares. Today, the Major Flare Watch
shall switch to this region due to its continued flux emergence,
especially in its leading portion. Additionally, NOAA 13767 (S09W85)
also produced an M1.7 flare in the period. Further M-class activity
is expected, with a chance for additional >M5 flares from various
regions in the following 24-48 hours.
The position of NOAA 13780 on 5-Aug-2024 at 11:30 UT is:
S10E64 (-838",-207")

Dear Collaborators,
Solar activity has returned to a high level since the last message.
Yesterday's target region NOAA 13765 was flare-quiet but its nearby
region NOAA 13766 (S07W90) was the source of three ~M1 flares
and four mid-to-high C-class flares in the period. A northeastern limb
region (N12E88) produced four M-class flares, including an M5.5 at
19:17 UT yesterday, and two mid-to-high C-class flares in the period.
Today, the Major Flare Watch shall switch to this limb region, although
NOAA 13775 (N17E11, beta-gamma/D-type) produced the largest
event during the period - an M7.3 flare at 18:29 UT yesterday. Further
M-class activity is expected, with a chance for >M5 flares from various
regions in the next 24-48 hours.
The approximate position of the target on 4-Aug-2024 at 11:30 UT is:
N12E88 (-924",192")

Dear Collaborators,
Solar activity has diminished since the last message. Yesterday's
target NOAA 13768 produced an M1.5 flare and six mid-to-high
C-class flares in the period, but is now completely out of view.
The largest event in the period was an M1.9 flare at 07:11 UT today,
produced by NOAA 13765 (S11W68, beta-gamma-delta/E-type).
13765 was also the source of two mid-to-high C-class flares in the
period. Today, the Major Flare Watch shall switch to NOAA 13765
due to its magnetic complexity, continued flux emergence, and the
complexity of the magnetic field connection between it and the
nearby active regions. Please note that a northeastern limb region
(N12E88) and some other active regions (NOAA 13775, 13766,
13777 and 13770) were also the source of M-class flares in the
period. Further M-class activity is expected, with a chance for >M5
flares from various regions in the next 24-48 hours.
The position of NOAA 13765 on 3-Aug-2024 at 11:30 UT is:
S11W68 (861",-215")

Dear Collaborators,
Solar activity has continued at a high level since the last message.
Target region NOAA 13768 has now rotated over the South West
limb, with some overlying loops visible above the limb. This region
produced two ~M1 flares and the largest magnitude flare in the period
- an M7.4 at 04:23 UT today. The Major Flare Watch shall remain in
effect with NOAA 13768 for a final 24 hours, as it rotates fully out of
view beyond the South West limb. Additionally, NOAA 13774 (beta-
gamma/E-type) produced five ~M1 flares during the period. Some
other active regions (NOAA 13765, 13772, 13766, 13764, and 13773)
also produced M-class flares. Further M-class activity is expected,
with a good chance for additional >M5 flares from various regions
in the next 24-48 hours.
The position of NOAA 13768 on 2-Aug-2024 at 11:30 UT is:
S16W91 (908",-257")

Dear Collaborators,
Solar activity remains at a high level. The largest event was an M8.2
flare peaking at around 07:10 UT today, produced by the southwest
limb region NOAA 13768 (S16W78). This region also produced another
M5.4 flare during the period. NOAA 13768 has retained a beta-gamma
-delta configuration but increased significantly in sunspot area. Today,
the target region will switch to NOAA 13768 before it completely rotates
over the west limb, due to its magnetic complexity and continued flux
emergence. Yesterday's target NOAA 13772 and some other active
regions (NOAA 13765, 13774, 13773, 13767, 13770, and 13762) also
produced several M-class flares, including an M6.3 flare at 01:47 UT
today from NOAA 13773 (S06W65, beta/C-type). Further M-class
activity is expected, with a good chance for additional >M5 flares in
the following 24-48 hours.
The position of NOAA 13768 on 1-Aug-2024 at 11:30 UT is:
S16W78 (889",-278")

Dear Collaborators,
Solar activity has returned to a high level since the last message. The
largest event was an M9.4 flare at 19:25 UT on July 30, produced by
the southeast region NOAA 13772 (S25E52, beta/D-type). This region
also produced an M6.0 flare peaking at 13:05 UT, happening just now.
Yesterday's target region, NOAA 13764 (S03W40, beta/D-type), was
the source of an M1.9 flare and two high C-class flares. Today, the
Major Flare Watch will switch to 13772. Additionally, some other active
regions located on the southern visible solar disk were the source of
M-class flares, including an unnumbered region near the east limb
(S07E88, M4.8) and some western active regions: NOAA 13768
(S16W64, beta-gamma-delta/E-type, M7.7), 13773 (S06W50, beta
/C-type, M2.0), and 13766 (S07W32, beta-gamma/E-type, M1.5).
Further M-class activity is expected with a good chance for additional
>M5 flares from various regions in the next 24-48 hours.
The position of NOAA 13772 on 31-Jul-2024 at 11:30 UT is:
