Dear Collaborators,
Solar activity has remained at a moderate level since the last
message. Several flares were produced in the last 24 hours, the
largest being an M1.2 from NOAA 13874 at 22:47 UT yesterday. NOAA
13780 remains classified as a beta-gamma-delta with a sustained area
of 1100 μh. Given the complexity and significant size of NOAA 13780,
the Major Flare Watch will continue with NOAA 13780 as the target
region, however attention should also be paid to NOAA 13784 due to the
notable dynamic sunspot activity from this region. Further C- and
M-class activity is expected, with a slight chance for an isolated >M5
event in the next 24-48 hours.
The position of NOAA 13780 on 13-August-2024 at 11:30 UT is:
S10W41, (613",-244")

Dear Collaborators,
Solar activity continues at a moderate level. Several flares were
produced over the last 24 hours, the largest being an M1.7 from NOAA
13777 at 19:57 UT yesterday. NOAA 13780 remains classified as a
beta-gamma-delta and has a significant area of 1100 μh, although the
number of associated sunspots has decreased substantially since the
last message. This region also shows sustained sunspot dynamism. The
Major Flare Watch will remain effective with NOAA 13780 as the target
region. Further C- and M-class activity is expected, with a slight
chance for an isolated >M5 event in the next 24-48 hours.
The position of NOAA 13780 on 12-Aug-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has decreased to a moderate level since the last message.
Target region 13780 (S10W16) was the most flare-productive region in
the period, being the source of eight mid-to-high flares and three low
M-class flares, including the largest magnitude in the period - an M1.6
flare at 05:23 UT today. 13780 gained a delta spot and is now classified
as a beta-gamma-delta/F-type sunspot group, with an area of 1200 MSH.
The Major Flare Watch shall remain in effect with NOAA 13780. Additionally,
NOAA 13782 (N03E21, beta/E-type) produced an M1.2 flare yesterday.
Further low M-class activity is expected, with a chance of >M5 flares in
the next 24-48 hours.
The position of NOAA 13780 on 11-Aug-2024 at 11:30 UT is:

Dear Collaborators,
Solar activity has continued at a high level since the last message.
The largest event was an M5.3 flare at 02:14 UT today, produced
by the target region NOAA 13780 (S12W04). This region also
produced another three ~M1 flares plus four mid-to-high C-class
flares in the period. 13780 has been reclassified as a beta-gamma
/F-type sunspot group with an area of 1280 MSH. We shall continue
the Major Flare Watch on this region today. Additionally, NOAA
13777 (S09W40, beta-gamma/E-type) and NOAA 13784 (N15E54,
beta/C-type) were also the sources of three M-class flares in the
period, including an M4.6 flare from NOAA 13777 yesterday. Further
M-class activity is expected, with a chance for additional >M5 flares
from various regions in the next 24-48 hours.
The position of NOAA 13780 on 10-Aug-2024 at 11:30 UT is:

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")
