Dear Collaborators,
Solar activity has returned to low levels. The largest event
since the last message was a C1.7 flare at 06:09 UT today
produced by the target region NOAA 13473. This region also
produced 2 C1.2 and 1 B-class flares. It retains a beta/B-type
magnetic configuration and has increased in spot counts. The
target region shall remain with NOAA 13473, due to its past
flaring history as well as a high and increasing current helicity.
Besides, NOAA 13471 (S23W53, beta-gamma/C-type) and
NOAA 13472 (N19E22, beta/C-type) were also sources of several
C1 and B-class flares. Further C-class flares are expected in
the following 24-hour period.
The position of NOAA 13473 on 28-Oct-2023 at 11:30 UT is:
N16E50 (-712", 216")

Dear Collaborators,
Solar activity has reached an intermediate due to an M1.4 at
22:47 UT on 26-Oct-2023 from an unnumbered region near
North East limb (N18E80). This region was close to the recently
numbered target region NOAA 13473. 13473 was now classified
as a beta/B-type sunspot group and the source of 3 low-C flares.
Today the target region shall still be 13473, but if possible, please
include the unnumbered region (N18E80) in your field of view.
Additionally, NOAA 13471 (S23W37, beta/D-type) and its nearby
spotless region also produced 3 low-C flares. Further C-class flares
are expected with a chance of another M-class flare in the next 24
hours.
The position of NOAA 13473 on 27-Oct-2023 at 07:30 UT is:
N13E58 (-799", 174")

Dear Collaborators,
Solar activity continues at low levels since the last message.
The target region (still unnumbered) has produced 3 C1 and
3 B-class flares. It should continue as the target region due to
its high flaring productivity and increasing current helicity.
Additionally, some plage regions (S15E81, N31W21, N17E43)
and NOAA 13471 (S23W27, beta/C-type) also produced some
low-C and B-class flares. More C-class flares are expected in
the following 24-hour period.
The approximate position of the target on 26-Oct-2023 at 11:30 UT is:
N09E77 (-890", 150")

Dear Collaborators,
Solar activity has increased slightly due to multiple low-C flares from
several regions. The most productive region over the North East limb
(unnumbered yet) was the source of 6 low-C and 7 high-B flares,
including the largest one that was a C2.6 at 00:38 today. The target
shall switch to this limb region due to its current level of flaring,
but if possible, please also include a spotless region (N16E59) in your
field of view, which produced the largest event being a C4.2 flare
at 23:49 on 24-Oct-2023. Yesterday’s target NOAA 13468 was
flare-quiet. Besides, another unnumbered region (S13E88) and
NOAA 13469 also produced a few low-C flares. Further C-class
activities are likely from various regions with a slight chance of a
low M-class flare in the next 24-hour period.
The approximate position of the target on 25-Oct-2023 at 11:30 UT is:
N14E88 (-900", 250")

Dear Collaborators,
Solar activity is still at a low level. The largest event since
the last message was a C2.3 flare at 19:47 UT on
23-Oct-2023 produced by the close pair of the target region
NOAA 13468 and a plage region (S14W25). 13468
(alpha/H-type) was stable in its magnetic complexity and
shall still be the target. Interested observers should also try
to include the plage region (S14W25) in their field-of-view if
possible. C-class activity is possible in the following 24 hours.
The position of NOAA 13468 on 24-Oct-2023 at 07:30 UT is:
S09W29 (463", -225")

MM#009 Default Target
Dear Collaborators,
Solar activity continues at low levels. Yesterday’s target
(NOAA 13467) did not produce any flares in the period,
while NOAA 13468 produced a single flare that was the
largest magnitude (a C1.5 flare at 06:58 UT today). This
region retains its alpha/H-type magnetic configuration,
so it becomes the new target. B-class activities are expected
with low C-class flares probable in the next 24 hours.
The position of NOAA 13468 on 23-Oct-2023 at 07:30 UT is:
S09W14 (231", -235")

Dear Collaborators,
The level of solar activity is very low. Target region NOAA 13469
remained stable since the last message, continuing to be classed
as a beta/D-type group. The plage region that was previously NOAA
13467 has regained this numbering after forming new spots. 13467
(an alpha/A-type group) becomes the new target. C-class activity
is possible in the next 24 hours.
The position of NOAA 13467 on 22-Oct-2023 at 20:00 UT is:
N14W37 , ( 565", 164" )

Dear Collaborators,
Solar activity is at a very low level. The target region at the North
West limb has rotated beyond Earth view. The plage region that used to
be NOAA 13467 produced the largest flare since the last message, a C2.8
on 21-Oct-2023 at 00:00 UT. Newly numbered NOAA 13469 (a beta/D-type
group) was the only spotted region showing any flux emergence, and this
becomes the new target. C-class activity is probable over the following
24-hour period.
The position of NOAA 13469 on 21-Oct-2023 at 18:30 UT is:
N27W47 , ( 628", 382" )

Dear Collaborators,
The level of solar activity is very low. The target region at the North
West limb has continued to be the source of all C-class activity since
the last message (five flares in total, including the largest magnitude
in the period as a C2.3 flare on 20-Oct-2023 at 04:20 UT. This location
remains as the target for the following 24 hours. Additional low C-class
flares are expected in the next 24 hours.
The approximate position of this region on 20-Oct-2023 at 20:00 UT is:
N25W90 , ( 873", 405" )
