Dear Collaborators,
Solar activity is at a low level. The target region has rotated
over the South East limb to show several spots, but remains too
close to the limb for accurate classification. This region has
produced B-class activity since the last message, including the
largest flare of the period (a B5.4 on 22-Oct-2021 at 08:29 UT).
Further B-class activity is expected in the following 24-hour
period, with a good chance for a C-class flare.
The approximate position of this region on 22-Oct-2021 at 16:00 UT is:
S24E72 , ( -838", -416" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA 12886 has remained
mostly stable, and continues to be classified as an alpha/H-type sunspot
group. This region has again remained flare quiet since the last message.
A coronal loop system (with some prominence/filament structures present)
is visible beyond the South East limb and has been the source of multiple
B-class flares, including the largest event of the period - a B8.7 flare
on 21-Oct-2021 at 15:02 UT (which may have been foot-point occulted, so
actually larger in magnitude). Further B-class activity is expected over
the next 24 hours, with a strong chance for C-class flares.
The approximate position of this region on 21-Oct-2021 at 18:00 UT is:
S23E90 , ( -887", -375" )

Dear Collaborators,
The level of solar activity is extremely low. The target region is now
designated as NOAA 12886, and it has been confirmed as an alpha/H-type
sunspot group. This region has been essentially flare quiet, with only
low A-class events recorded since the last message. B-class flares may
be possible over the next 24 hours.
The position of NOAA 12886 on 19-Oct-2021 at 13:00 UT is:
S19E54 , ( -737", -365" )

Dear Collaborators,
Solar activity is at a very low level. NOAA 12882 has now fully
rotated over the North West limb. A new spotted region rotated
over the South East limb, but it has not yet been given a NOAA
number. This region appears to be an alpha/H-type sunspot group
and has produced low B-class activity since the last message -
the largest being a B1.2 flare on 18-Oct-2021 at 03:23 UT. This
new spot region becomes the target. B-class activity is likely
in the following 24-hour period.
The approximate position of this region on 18-Oct-2021 at 20:30 UT is:
S19E66 , ( -833", -348" )

Dear Collaborators,
The level of solar activity is very low. Target region NOAA 12882 has
rotated over the North West limb, with its higher-lying loops still
visible. This region produced four low B-class flares since the last
message, the largest of which was a B1.8 on 17-Oct-2021 at 06:16 UT.
The target will remain on the limb-crossing location of NOAA 12882.
Further low B-class activity is probable over the next 24 hours.
The approximate position of this region on 17-Oct-2021 at 14:30 UT is:
N15W90 , ( 930", 248" )

Dear Collaborators,
Solar activity is at a very low level. Target NOAA 12885 has now
rotated over the North West limb, but its higher-lying loops are
still visible. NOAA 12882 remained stable since the last message
with its classification decreasing to an alpha/H-type due to limb
foreshortening. A few low B-class flares have occurred from the
limb-crossing location of NOAA 12885 and also from NOAA 12882.
B-class activity is probable in the following 24-hour period.
The position of NOAA 12882 on 16-Oct-2021 at 16:00 UT is:
N15W85 , ( 926", 240" )

Dear Collaborators,
The level of solar activity is low. NOAA 12882 has remained
stable since the last message, continuing to be classified
as a beta/C-type sunspot group. Target NOAA 12885 has now
rotated close to the North West limb, making classification
of its magnetic complexity and morphology impossible. NOAA
12885 produced the largest flare since the last message - a
B9.7 on 15-Oct-2021 at 15:01 UT. The target remains as the
limb-crossing location of NOAA 12885 for the next 24 hours,
but observers should try to include NOAA 12882 within their
field-of-view if at all possible. Further B-class activity
is expected, with a chance for a low C-class flare as NOAA
12885 crosses the North West limb.
The position of NOAA 12885 on 15-Oct-2021 at 16:00 UT is:
N15W90 , ( 929", 248" )

Dear Collaborators,
Solar activity is at a low level. NOAA 12882 has continued to
decay to become a beta/C-type sunspot group. The target region
is now designated as NOAA 12885, a beta/C-type sunspot group.
NOAA 12885 continued producing B-class activity and also three
C-class flares since the last message, the largest being C2.2
on 14-Oct-2021 at 01:24 UT. B-class activity is expected over
the next 24 hours, with a chance for another C-class flare as
NOAA 12885 rotates up to the North West limb.
The position of NOAA 12885 on 14-Oct-2021 at 20:00 UT is:
N15W78 , ( 909", 228" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA 12882 emerged
new flux since the last message to increase in complexity and become
a beta-gamma/D-type sunspot classification. This region has continued
producing B-class flares, including the largest event of the period
(a B5.9 on 12-Oct-2021 at 15:54 UT). However, a new spot region is in
the process of emerging approximately 10 degrees West of NOAA 12882.
This will become the new target due to its rate of emergence and its
proximity to NOAA 12882. Further B-class activity is expected in the
following 24-hour period, with a chance for C-class if the new region
emerges trailing polarity flux close to the leading polarity spot of
NOAA 12882.
The approximate position of this region on 13-Oct-2021 at 18:00 UT is:
N16W65 , ( 839", 223" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 12882 has decayed
somewhat since the last message to become a beta/C-type sunspot group
classification. This region has continued to produce B-class activity,
including the largest event of the period (a B9.5 flare on 12-Oct-2021
at 01:36 UT). NOAA 12883 also produced low B-class flares, but fewer
than 12882. Additional B-class activity is expected over the next 24
hours, with a small chance for an isolated C-class flare.
The position of NOAA 12882 on 12-Oct-2021 at 13:00 UT is:
N16W35 , ( 534", 184" )
