Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13451
was stable in spot area since the last message, maintaining its
beta-gamma/D-type classification. This region produced several
C-class flares in the period, along with the largest magnitude
flare - an M2.3 on 10-Oct-2023 at 12:08 UT. Another low M-class
flare (an M1.6 on 10-Oct-2023 at 01:55 UT) was produced between
NOAA 13451 and the nearby NOAA 13452 (a beta/E-type group). More
C-class activity is expected over the next 24 hours, with a good
chance for another M-class flare.
The position of NOAA 13451 on 10-Oct-2023 at 18:00 UT is:
N17W70 , ( 864", 245" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13460 grew
slightly since the last message, and was also confirmed as being
a beta-gamma/D-type classification. This region produced several
C-class flares in the period, while previous target NOAA 13451
(now a beta-delta/E-type group) was the source of more C-class
activity as well as the largest flare - a C7.6 on 9-Oct-2023 at
11:28 UT. The target now switches back to NOAA 13451 due to its
magnetic classification. Further C-class flares are expected in
the following 24-hour period, with a small chance remaining for
a low M-class flare.
The position of NOAA 13451 on 9-Oct-2023 at 18:00 UT is:

Dear Collaborators,
The level of solar activity is at a low-to-moderate. Target region
NOAA 13451 grew slightly since the last message, being reclassified
into a beta-gamma/E-type group. This region again produced a number
of C-class flares in the period but the largest flare (an M1.7 on
7-Oct-2023 at 17:57 UT, just after yesterday's email was sent) came
from NOAA 13460, an numbered sunspot group at that time. NOAA 13460
was initially designated as an alpha/A-type at the start of the UT
day, but it was at a very early point in its emergence - 13460 now
appears to be a beta-gamma/D-type configuration. Additional C-class
activity is expected over the next 24 hours, with a good chance for
another low M-class flare.
The position of NOAA 13460 on 8-Oct-2023 at 18:00 UT is:
S11E25 , ( -401", -277" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13451 was stable
in spot area and number of spots since the last message, maintaining
a beta-gamma/D-type group classification. NOAA 13451 again produced
most of the flares in the period including the largest magnitude - a
C3.5 on 7-Oct-2023 at 07:58 UT. Further C-class flares are expected
in the following 24-hour period.
The position of NOAA 13451 on 7-Oct-2023 at 18:00 UT is:

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13451 has grown
slightly since the last message, increasing in magnetic complexity to
be designated as a beta-gamma/D-type group. This region again produced
most of the flares in the period including the largest magnitude flare
- a C4.7 flare on 5-Oct-2023 at 19:03 UT. Nearby region NOAA 13452 (a
beta-gamma/E-type group) showed signs of decay and produced one C-class
flare. Additional C-class activity is expected over the next 24 hours.
The position of NOAA 13451 on 6-Oct-2023 at 18:00 UT is:

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13450 has
continued to decay since the last message, decreasing slightly
in spot area and magnetic classification to be designated as a
beta/E-type group. This region produced just one C-class flare
in the period, while most of the remaining flares came from the
close pair of NOAA regions 13451 (a beta/D-type group with five
C-class flares) and 13452 (a beta/E-type group, with one C-class
flare). The target switches to 13451 which is the smaller spot
group, but produced the largest magnitude flare (a C3.8 flare
on 5-Oct-2023 at 06:51 UT). Interested observers should try to
include 13452 in their field-of-view as well if possible. More
C-class flares are expected in the following 24-hour period.

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13450 has
decayed since the last message, decreasing in both spot area and
number of spots while remaining classified as a beta-gamma/E-type
group. This region has continued to produce C-class activity, but
at a lower rate than the previous day. Additional C-class flares
are expected over the next 24 hours.
The position of NOAA 13450 on 4-Oct-2023 at 20:00 UT is:

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13451 has decayed
further since the last message, decreasing in spot area and magnetic
complexity to a beta/D-type group classification. NOAA 13451 has been
flare-quiet in the period, while NOAA 13450 (a beta-gamma/E-type group)
has produced the most flares - 9 C-class flares, including the largest
flare that was a C3.6 on 3-Oct-2023 at 16:56 UT. The target switches to
NOAA 13450 due to its higher complexity and current level of flaring.
Further C-class activity is expected in the following 24-hour period.
The position of NOAA 13450 on 3-Oct-2023 at 20:00 UT is:
S18W07 , ( 111", -400" )

Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA
13451 has decayed slightly since the last message, but remained as
a beta-delta/D-type group classification at the start of the UT day
(although it may have now lost its delta configuration). NOAA 13451
has produced two C-class flares in the period, while an unnumbered
small spot region in the North East quadrant was the source of the
largest flare - an M1.9 on 2-Oct-2023 at 12:35 UT. The target will
remain with NOAA 13451 due to its past flaring history and proximity
to NOAA 13452. Additional C-class activity is expected over the next
24 hours.
The position of NOAA 13451 on 2-Oct-2023 at 20:00 UT is:
N16E37 , ( -557", 178" )

Dear Collaborators,
Solar activity has reached an intermediate level since the last message.
The largest event in the period was an M2.5 flare at 01:10 UT today
produced by the target region that has been numbered as NOAA 13451
(N14E56). 13451 is now classified as a beta-delta/D-type sunspot region
and produced another M1.2 plus eleven C-class flares in the period.
Today the target shall still be this region. Additionally, NOAA 13445
(S14W83, alpha/H-type) also produced two C9 and one C4 flares during
its approach to the South West limb. More C-class flares are expected
in the following 24-hour period, with a good chance for further low
M-class flares.
The position of NOAA 13451 on 1-Oct-2023 at 07:30 UT is:
N14E56 (-772" , 169")
