Dear Collaborators,
Solar activity is at a mid-to-low level. The largest event since
the last message was an M1.8 flare at 01:18 UT today from
yesterday's target region NOAA 14168 (N05W91). 14168
continues to be the most flare-productive region, producing
over ten C-class flares and four additional low M-class flares
during the period. This region has now rotated beyond the
northwest limb, with overlying loops visible above the limb.
In addition, a northeast limb region (N08E89, unnumbered)
and NOAA 14172 (N08W27) have also produced several
mid-to-high C-class flares. 14172 has a beta-gamma configuration
and is experiencing notable flux emergence near its intermediate
portion. Today, the target region will switch to NOAA 14172.
Further C-class activity is expected, with the possibility of low
M-class flares in the next 24 hours.
The position of NOAA 14172 on 12-Aug-2025 at 15:30 UT is:
N08W27 (427",36")

Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA 14168
(N05W85) remained the most flare-productive region on the visible disk,
producing over ten C-class flares and four low M-class flares, including
the largest event of the period—an M2.3 flare at 14:57 UT yesterday,
which exhibited prominent supra-arcade downflows (see SSW Latest

Events entry
<https://www.lmsal.com/solarsoft/latest_events/#M2.3_AR_4168_N04W79_Supra_Ar…>).
NOAA 14168 will remain the target region until it fully
rotates over the west limb. C-class activity is expected, with a chance
of additional low M-class events in the next 24 hours.
The position of NOAA 14168 on 11-Aug-2025 at 11:30 UT UT is:
N05W85 (939",72")

Dear Collaborators,
Solar activity has continued at a mid-low level. Several flares were
produced since the last message, including two M1.7 flares from NOAA 14168
at 16:33 UT yesterday and 02:46 UT today, respectively. The classification
of NOAA 14168 has switched to beta-gamma, however this may be a projection
effect as the region approaches the solar limb. While the region remains
active and in view NOAA 14168 will remain the target region. Further
C-class activity is expected with a chance for additional isolated M-class
events.
The position of NOAA 14168 on 10-August-2025 at 03:30 UT is
N05W66, (862", 39")

Dear Collaborators,
Solar activity has continued at a low-to-mid level since the last message.
Several flares were produced, the largest being an M1.0 from NOAA 14168 at
18:56 UT yesterday. NOAA 14168 continues to be the dominant source of
activity and retains its complexity while continuing to increase in
apparent sunspot area. NOAA 14168 will remain the target region, with
further C-class activity expected and a chance for additional isolated
M-class flares.
The position of NOAA 14168 on 09-August-2025 at 11:30 UT is

Dear Collaborators,
Solar activity has remained consistent over the last 24 hours. NOAA 14168
continues to be the dominant active region, producing several flares, the
largest being an M2.8 at 03:29 UT today. NOAA 14168 remains classified as a
beta-gamma-delta, however levels of dynamism in this region have slightly
reduced. NOAA 14168 will continue as the target region, further C-class
activity is expected with a chance for additional isolated M-class events.
The position of NOAA 14168 on 08-August-2025 at 11:30 UT is
N05W44, (656", 7")

Dear Collaborators,
Solar activity has further increased since the last message. Numerous
flares were produced in the last 24 hours, the largest being an M3.9 from
NOAA 14168 at 10:40 UT today. NOAA 14168 continues to demonstrate
considerable dynamism and elevated flux. Activity levels from NOAA 14168
remain high and this region will continue as the target region for the next
24 hours. Further C-class activity is expected with additional isolated
M-class events.
The position of NOAA 14168 on 07-August-2025 at 15:30 UT is
N05W52, (501", -4")

Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA 14168
was the site of an M4.4 flare at 05:47 UT today. NOAA 14168 remains small
in apparent sunspot area, but shows complexity, retaining its
beta-gamma-delta classification, and demonstrates continued sunspot
dynamism. NOAA 14168 will continue as the target region, further isolated
M-class activity is expected in the next 24 hours.

Dear Collaborators,
Solar activity returns to a low level. NOAA 14168 produced several flares,
the largest being an M1.2 at 02:00 UT today. NOAA 14167 has reduced in
apparent complexity and size, however we note that this region is also
positioned at the northwestern limb and subject to projection effects. NOAA
14168 remains classified as a beta-gamma-delta and continues to show signs
of increased sunspot dynamism. Given the location and sustained activity
from this region, NOAA 14168 will be the new target region for the next 24
hours. Additional C- and M-class activity is anticipated.
The position of NOAA 14168 on 05-August-2025 at 11:30 UT is
N05W04, (65", -17")

Dear Collaborators,
Solar activity has slightly increased. Multiple flares were produced over
the last 24 hours, the largest being an M2.9 from NOAA 14168 at 13:50 UT
yesterday. Both NOAA 14167 and NOAA 14168 have developed into
beta-gamma-delta regions, with NOAA 14167 increasing in size to 430 μh.
Both regions have demonstrated an increase in sunspot dynamism. While NOAA
14167 will remain the target region, additional attention should be paid to
NOAA 14168, with potential for a Major Flare Watch to be initiated in the
next 24-48 hours. Chances of further isolated M-class flares in the next
24-48 hours.
The position of NOAA 14167 on 04-August-2025 at 11:30 UT is
N10W59, (799", 113")

Dear Collaborators,
Solar activity continues at a low level. NOAA 14167 produced a number of
flares in the last 24 hours, the largest being a C3.5 at 09:17 UT today.
NOAA 14167 has almost quadrupled in size since the last message, but shows
a reduction in dynamic sunspot behaviour. This region remains classified as
a beta-gamma region and shall continue to be monitored as the target
region. Additional C-class activity is expected in the next 24 hours.
The position of NOAA 14167 on 03-August-2025 at 11:30 UT is
N12W45, (665", 128")
