Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13101
grew slightly since the last message, increasing in complexity to
be classified as a beta-gamma/D-type sunspot group. This region
continued to produce multiple C-class flares in the period on its
way to rotating up to the North West limb. Previous target region
NOAA 13098 (still classified as a beta-gamma/E-type sunspot group)
was also the source of multiple C-class flares and an M1.7 flare
on 12-Sep-2022 at 23:37 UT. The target will switch to NOAA 13098
due to its flaring history and NOAA 13101 currently rotating over
the limb. High C-class flares are expected in the next 24 hours,
with a good chance for additional M-class flaring.
The position of NOAA 13098 on 13-Sep-2022 at 14:30 UT is:
N18W44 , ( 631", 211" )

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13100
has been stable in terms of spot area and number of spots since
the last message, remaining classified as a beta/C-type sunspot
group. This region was flare-quiet in the period, while previous
target NOAA 13098 increased in magnetic complexity to become a
beta-gamma/E-type sunspot group and returned to C-class flaring.
The recently numbered NOAA 13101 in the North West quadrant has
also increased in structural complexity to be classified as a
beta/D-type sunspot group and has been the source of multiple
C-class flares since the last message, including the largest of
the period - a C7.4 on 12-Sep-2022 at 12:55 UT. The target will
switch to NOAA 13101 because of its recent higher frequency of
flaring compared to NOAA 13098. Further high C-class flares are
expected over the following 24-hour period, with a good chance
for an M-class flare.
The position of NOAA 13101 on 12-Sep-2022 at 15:00 UT is:
N29W79 , ( 819", 439" )

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C2.8 flare at 09/10/23:49 UT
produced by the newly emerged region as mentioned in the
last message, now being numbered as NOAA 13100. 13100
also produced another 7 low C-class flares. Today the target
will switch to this region, which has a beta/C-type configuration.
Yesterday's target NOAA 13098 retains a beta/C-type classification
and was the source of two C1 flares during the period. Additional
C-class activities are expected in the next 24 hours.
The position of NOAA 13100 on September 11 at 07:30 UT is:
S25E44 (-601", -478")

Dear Collaborators,
Solar activity continues at a very low level with the soft X-ray
flux around ~C1 level. The target region NOAA 13098 was the
source of a C1.1 at 09/09/21:02 UT. NOAA 13097 (S11W27)
also produced a C1.1 flare at 09/09/15:30 UT. A newly emerged
region near the south-east limb (S23E66) was the source of a
C1.0 flare plus three high B-class flares. The target NOAA 13098
has been designated as a beta/C-type sunspot group today. It
is showing mixed polarities in its leading portion. B- and C-class
activities are expected in the following 24 hours.
The position of NOAA 13098 on September 10 at 03:30 UT is:
N17E03 (-47", 162")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
in the past 24 hours was a C2.1 flare at 09/08/16:57 UT produced
by a newly emerged region numbered as NOAA 13098. 13098
also produced four ~C1 flares. Today we will watch this region.
It was designated as a beta/B-type region but continues to show
flux emergence. If possible, please also include NOAA 13094
(N17W03) in the field of view, which produced a C1.2 flare.
Yesterday's target NOAA 13096 was the source of two low C-class
flares during the period. Further C-class activities are expected
from various regions in the next 24 hours.
The position of NOAA 13098 on September 9 at 07:30 UT is:
N15E13 (-207", 131")

Dear Collaborators,
Solar activity continues at a low level with the soft X-ray flux
flat at ~C1 in general. The target region NOAA 13096 was the
source of four C1 flares. 13096 has been classified as a beta/
D-type region today. New spots continue to emerge from this
region. Additional C-class activities are expected in the next
24 hours.
The position of NOAA13096 on September 8 at 07:30 UT is:

Dear Collaborators,
Solar activity has been at a very low level since the last message.
Yesterday's target region NOAA 13089 was the source of seven
low C-class flares during the period, the largest one being a C3.2
at 09/06/18:21 UT. 13089 has now completed its west limb passage.
Today the target will switch to NOAA 13096 which is increasing in
its sunspot area and number of spots. C-class activities are expected
in the next 24 hours.
The position of NOAA13096 on September 7 at 15:30 UT is:

Dear Collaborators,
The target region NOAA 13089 was the source of more than
10 C-class flares as well as an M1.0 flare (at 09/05/17:58 UT)
since the last message. 13089 was designated as a beta-gamma/
E-type configuration. It is almost rotating beyond the west limb.
We will watch this region for a further 24 hours. Limb or occulted
C-class flares are expected with some chance of a low M-class
flare in the next 24 hours.
The position of NOAA13089 on September 6 at 03:30 UT is:
S23W90 (875", -368")

Dear Collaborators,
The target region NOAA 13089 was the source of numerous
C-class flares in the past 24 hours, the largest one being a C8.2
at 09/04/16:30 UT. 13089 retains its beta-gamma-delta/E-type
configuration and is rotating over the west limb. Further C-class
activities are expected, still with a chance of a low M-class flare
in the next 24 hours.
The position of NOAA13089 on September 5 at 07:30 UT is:
S23W78 (856", -391")

Dear Collaborators,
NOAA 13089 has continued to produce C-level activity since the last
message, the largest event being a C6.4 at 02:51 UT today. The target
region has once again grown in size and complexity as it approaches
the western limb, and has regained its beta-gamma-delta configuration.
Further C-class events likely over the next 24 hours with chance for
an M-class flare before west limb passage.
The position of NOAA 13089 on 4-Sep-2022 at 07:30 UT is:
S22W65, ( 800", -400" )
