Dear Collaborators,
Solar activity is very low. Several small flares were produced, the largest
being a C1.6 from NOAA 14210 at 13:47 UT yesterday. NOAA 14213 remains
classified as a beta-gamma type region, however this region has produced
little activity since the last message. Further B-class and low C-class
activity is expected in the next 24 hours.
The position of NOAA 14213 on 10-September-2025 at 11:30 UT is
S14W19, (302", -340")

Dear Collaborators,
Solar activity remains at a low level. A small number of flares were
produced, the largest being a C1.5 from NOAA 14207 at 03:17 UT today. NOAA
14213 is now classified as a beta-gamma region and still shows reasonable
levels of sunspot activity. NOAA 14213 will continue as the target region,
further C-class activity is expected in the next 24 hours.
The position of NOAA 14213 on 09-September-2025 at 11:30 UT is
S14W05, (80", -346")

Dear Collaborators,
Solar activity has reduced since the last message. A number of flares have
been produced since the last message, the largest being a C4.0 from NOAA
14213 at 17:56 UT yesterday. NOAA 14207 has shown signs of decay since the
last message and is now classified as a beta-type region. NOAA 14213 has
developed quickly in the last few days and shows signs of increased
activity. The target region will switch to NOAA 14213 for the next 24
hours. Further C-class activity is anticipated.
The position of NOAA 14213 on 08-September-2025 at 11:30 UT is
S13E08, (-129", -329")

Dear Collaborators,
Solar activity has reached an intermediate level since the last message.
The largest event during the period was an M1.2 flare at 22:07 UT
yesterday from the target region NOAA 14207. This region retains a
beta–gamma configuration and produced over ten additional C-class
flares, including a C9.6 flare. Today, we will continue to watch NOAA
14207. Additionally, two mid-C-class flares (C4.5 and C5.1) were
produced by the west limb (likely from NOAA 14199), accompanied
by a CME (see the SSW Latest Events entry
<https://www.lmsal.com/solarsoft/latest_events/#Double_Eruption_Double_CME_O…>).
Further C-class activity
is expected, with a chance of additional low-M-class flares in the
following 24–48 hours.
The position of NOAA 14207 on 7-Sep-2025 at 11:30 UT is:
N29W28 (392",366")

Dear Collaborators,
Solar activity has slightly decreased since the last message. The
largest event during the period was a C4.9 flare at 10:30 UT today
from the southwest limb (likely NOAA 14197, S18W91), which also
produced several additional low C-class flares. The target region,
NOAA 14207 (N29W10), has developed into a beta–gamma
configuration and produced a C4.5 flare together with four additional
low C-class flares in the period. This region continues to show new
magnetic flux emergence in its intermediate and trailing portions.
Today, NOAA 14207 will remain the default target. Further C-class
activity is expected, with a chance of low M-class flares in the next
24–48 hours.
The position of NOAA 14207 on 6-Sep-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity has increased to a moderate level since the last message.
The two largest events during the period were an M1.4 flare at 01:08 UT
today and an M1.0 flare at 13:36 UT yesterday, both from the target region
NOAA 14207 (N29E03, beta/F-type). This region continues to show signs
of flux emergence and will remain the target region. Further C-class
activity
is expected, with a chance of additional low M-class flares in the next
24–48
hours.
The position of NOAA 14207 on 5-Sep-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity has further increased since the last message. The largest
event during the period was a C9.2 flare at 05:22 UT today from NOAA
14207 (N30E17, beta/F-type), which also produced five additional low
C-class flares. Today, the default target shall switch to this region due
to
its ongoing flux emergence. In addition, NOAA 14211 (S14E49, alpha/H-
type), 14199 (N04W58, beta/C-type), and yesterday’s target region NOAA
14197 (S18W72, beta/F-type) produced several more low C-class flares
during the period. Further C-class activity is expected, with a chance of
an isolated M-class flare in the next 24-48 hours.
The position of NOAA 14207 on 4-Sep-2025 at 11:30 UT is:

Dear Collaborators,
Solar activity has slightly increased since the last message. The largest
event during the period was a C6.1 flare at 14:39 UT yesterday from
NOAA 14199 (N04W43, beta/C-type). The target region, NOAA 14197
(S18W59), retains a beta–gamma/E-type configuration but has shown
decreases in sunspot area and number as it rotates toward the west limb.
14197 produced ten C-class flares during the period, including C4.2 and
C4.9 flares yesterday. Today, we will continue to watch this region.
Additional C-class activity is expected in the next 24 hours.
The position of NOAA 14197 on 3-Sep-2025 at 11:30 UT is:
S18W59 (776",-350")

Dear Collaborators,
Solar activity has been low since the last message. The largest event
in the period was a C3.9 flare at 19:14 UT yesterday from the target
region NOAA 14197 (S18W45). This region retains a beta–gamma/E-
type configuration and produced several other low C-class flares during
the period. The default target shall remain with NOAA 14197 today.
Additionally, NOAA ARs 14207 (N30E45; beta/E-type), 14201 (S22W30;
alpha/H-type), 14191 (N11W89; beta/C-type), and 14199 (N04W29;
beta/C-type) were the sources of several C2–C3 flares over the past
24 hours. Additional C-class activity is expected in the next 24 hours.
The position of NOAA 14197 on 2-Sep-2025 at 11:30 UT is:
S18W45 (641",-372")

Dear Collaborators,
Solar activity has decreased to a moderate-to-low level. The largest
event since the last message was a C6.8 flare at 17:58 UT yesterday
from NOAA 14202 (S15W12, alpha/H-type). The target region, NOAA
14197 (S18W31), has decayed to a beta-gamma configuration yet
produced more than ten low C-class flares during the period, the
largest being C4.9 at 03:03 UT today. NOAA 14197 shall remain the
target region, due to its activity history and magnetic complexity. In
addition, a northeast region NOAA 14207 (N30E51, beta/E-type)
produced five low C-class flares in the period. Further C-class activity
is expected, with a chance of an isolated M-class flare in the next 24
hours.
The position of NOAA 14197 on 1-Sep-2025 at 11:30 UT is:
S18W31 (467",-389")
