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:

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:

Dear Collaborators,
Solar activity has been at a high-to-intermediate level. The
largest event since the last message was an M6.4 flare at
19:40 UT from an unnumbered region near the South East
limb (S25E70). This region also produced an M4.3 flare at
14:04 UT yesterday. The target region NOAA 13764 has
decayed slightly in sunspot area and number of spots and
was confirmed as an alpha/H-type configuration, while NOAA
13766 (S07W18) emerged new spots to be classified as a
beta-gamma-delta/E-type region. This close pair of NOAA
regions only produced two M1 flares in the period. Today the
Major Flare Watch region will continue as NOAA 13764 due
to its past >M5 activities and proximity to NOAA 13766.
Further low-M activities are expected with a good chance
for additional >M5 flares from various regions in the following
24 hours.
The position of NOAA 13764 at 11:30 UT on 30-Jul-2024 is:
S03W26 (415", -133")

Dear Collaborators,
The level of solar activity has still been high since the
last message. The largest event was an X1.5 flare at
02:33 UT today from the target region between 13764
and NOAA 13766. 13764 has been classified as a
beta/C-type sunspot group and 13766 (S07W03) has
retained a beta/D-type configuration over the past 24
hours. Their intermediate portion with mixed polarities
appears to be away from 13766 and thus closer to
13764. Today the Major Flare Watch will switch to 13764
(with NOAA 13766 in the field of view). In addition, NOAA
13762 (beta-gamma-delta/F-type, S11W49) also produced
an M7.8 flare at 10:27 UT yesterday and an M8.7 flare at
12:47 UT today. Further low-M activities are expected with
a good chance for additional >M5 flares in the following
24 hours.
The position of NOAA 13764 at 11:30 UT on 29-Jul-2024 is:
S03W13 (213", -139")

Dear Collaborators,
Solar activity has reached a high level. The largest events
since the last message were two consecutive high-M flares
from two adjacent active regions, NOAA 13766 and 13764.
The two flares include an M7.9 at 01:39 UT and an M9.9 at
01:53 UT today eruptive with dimming and coronal waves.
13766 has developed to be a beta/D-type configuration and
13764 (S05E04) has been classified as an alpha/H-type
sunspot group, both of which are surrounded by the other
three active regions (NOAA 13763, 13765, and 13767).
At this time, we are implementing a Major Flare Watch on
NOAA 13766 (with NOAA 13764 in the field of view).
Yesterday’s target region NOAA 13762 (beta-gamma-delta/F-type,
S12W34) was a source of three low-to-mid M-class flares.
Further low-M activities are expected with a good chance
for another>M5 flare in the following 24-48 hours.
The position of NOAA 13766 at 07:30 UT on 28-Jul-2024 is:
S07E15 (-243", -202")

Dear Collaborators,
Solar activity has increased to a mid-M level since the
last message. The largest event, an M4.2 flare at
02:21 UT today, came from NOAA 13766 (beta/C-type,
S07E21) which has displayed separation of its main spots
and emerged new spots in the period. The target region
NOAA 13762 produced an M3.1 flare at 05:12 UT plus an
M2.0 flare at 10:16 UT today. 13762 has also emerged new
spots in its leading portion, with a beta-gamma-delta/F-type
magnetic configuration. Today 13762 should remain with the
target region due to its higher magnetic complexity. Further
C-class activities are expected with a good chance for more
low-to-mid M-class flares from the two regions in the following
24 hours.
The position of NOAA 13762 at 11:30 UT on 27-Jul-2024 is:
S12W27 (420", -274")

Dear Collaborators,
Solar activity has returned to a moderate level due to two
low-M flares, including an M1.7 flare at 04:30 UT today
from NOAA 13761 (beta-gamma/D-type, S10W77) and
an M1.3 flare at 15:27 UT yesterday from NOAA 13751
(beta-gamma/D-type, S08W91). The target region NOAA
13762 only produced several C-class flares in the period,
with the largest being a C5.8 flare at 11:20 UT today. This
region has increased in spot maturity to display penumbra
on its leading spots, changing to a beta-gamma-delta/F-type
sunspot group. 13762 will continue to be the target region
for a further 24 hours. Further C-class activities are expected
with a chance for additional low-M flares from various regions
in the next 24 hours.
The position of NOAA 13762 at 11:30 UT on 26-Jul-2024 is:
S12W11 (176", -281")

Dear Collaborators,
Solar activity has been at a moderate-to-low level in the
past 24 hours. The largest event, an M2.9 flare at 17:07 UT
yesterday, came from NOAA 13751 (beta-gamma/D-type,
S08W77). The target region NOAA 13762 also produced
two high-C flares, including a C8.4 at 00:24 UT and a C9.1
at 01:54 UT today). It has remained a beta-gamma-delta/E-type
sunspot group and continued to grow slightly in the number of
sunspots and spot area. Further C-class activities are expected
with another low-M flare possible in the following 24 hours.
The position of NOAA 13762 at 11:30 UT on 25-Jul-2024 is:
S12E03 (-48", -281")

Dear Collaborators,
The level of solar activity remains moderate due to an
M3.6 flare at 07:28 UT today from NOAA 13751
(beta-gamma-delta/E-type, S08W63). This region continues
to reduce in sunspot area and number as it transits towards
the South West limb. The target region NOAA 13762 retains
a beta-gamma-delta/E-type sunspot group, with a significant
emergence of negative magnetic fluxes in its intermediate
portion. 13762 should continue as the target region. Further
C-class activities are expected with an additional low-M flare
possible in the next 24 hours.
The position of NOAA 13762 at 11:30 UT on 24-Jul-2024 is:
S12E17 (-271", -276")
