Dear Collaborators,
Solar activity persists at a low level, only four numbered active regions
are currently viewable on the solar disk. The largest flare in the last 24
hours was a C3.5 from an unnumbered active region in the southeastern
quadrant of the solar disk at 09:27 UT today. While this unnumbered region
continues its transit onto the solar disk, the target region will remain as
NOAA 14216. Further C-class activity is expected over the next 24 hours.
The position of NOAA 14216 on 14-September-2025 at 11:30 UT is
N10E45, (-666", 81")

Dear Collaborators,
Solar activity remains low. The largest flare of the last 24 hours was a
(partially occulted) C1.5 from an unnumbered active region in the
southeastern quadrant at 07:33 UT today. NOAA 14216 has traversed further
onto the disk, but has shown minimal additional activity since the last
message. However, NOAA 14216 will continue as the target region for the
next 24 hours. Additional low C-class activity is expected.
The position of NOAA 14216 on 13-September-2025 at 15:30 UT is
N10E54, (-761", 95")

Dear Collaborators,
Solar activity continues at a very low level. NOAA 14207 was the site of
several flares close to the solar limb, the largest being a C7.6 at 15:09
UT yesterday. NOAA 14213 has shown signs of decay, now classified as a beta
type region. Since the last message, this region has produced no new
flares. NOAA 14216 is a newly numbered active region on the northeastern
edge of the solar disk and shows notable emerging flux. Due to the
inactivity of NOAA 14213, the target region will switch to NOAA 14216 for
the coming 24 hours. Further C-class activity is anticipated.
The position of NOAA 14216 on 12-September-2025 at 11:30 UT is
N09E70, (-885", 107")

Dear Collaborators,
Solar activity remains at a very low level. Further small flares were
produced, with the largest flare of the last 24 hours being a C1.5 from
NOAA 14207 at 05:55 UT today. While NOAA 14213 continues to be classified
as a beta-gamma type region, no flares have been produced from this region
since the last message. However, NOAA 14213 will remain the target region
for a further 24 hours due to the continued global low levels of activity.
Additional low C-class activity is expected.
The position of NOAA 14213 on 11-September-2025 at 11:30 UT is
S14W34, (518", -326")

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

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:
N29W10 (145",355")

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:
