Dear Collaborators,
Solar activity is at a low level. Target NOAA 12891 decayed
since the last message but has maintained its classification
as a beta/D-type sunspot group. NOAA 12887 was the source of
the largest event of the period (a C2.0 flare on 3-Nov-2021
at 20:56 UT) but has now rotated over the South West limb.
NOAA 12891 continues as the target region. B-class activity
is expected over the next 24 hours, with a chance for a low
C-class flare.
The position of NOAA 12891 on 3-Nov-2021 at 23:30 UT is:
N16W39 , ( 586", 215" )

Dear Collaborators,
The level of solar activity is moderate-to-high. Target NOAA 12887
decayed somewhat since the last message, although it was reported
as increasing in magnetic complexity to beta-gamma/C-type sunspot
group classification at the start of the UT day. NOAA 12891 showed
minor evolution since the last message, but produced a C2.0 flare
and the largest event of the period - an M1.7 flare on 2-Nov-2021
at 02:57 UT. NOAA 12891 becomes the new target region. Additional
C-class activity is probable in the following 24-hour period, with
a chance for another M-class flare.
The position of NOAA 12891 on 2-Nov-2021 at 16:30 UT is:
N16W06 , ( 98", 199" )

Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 12887 has
decayed somewhat since yesterday's message, now being classified as
a beta/C-type sunspot group. Both NOAA 12887 and 12891 have been the
source of C-class flares, with 12887 producing the largest flare in
the period - an M1.5 on 1-Nov-2021 at 00:57 UT. NOAA 12887 continues
as the target region. Further C-class activity is probable over the
next 24 hours, with a chance for another M-class flare.
The position of NOAA 12887 on 1-Nov-2021 at 21:00 UT is:
S28W58 , ( 726", -487" )

Dear Collaborators,
Solar activity has diminished over the last 24 hours. NOAA 12887 and
NOAA 12891 have continued to produce low C-level activity. NOAA 12887
retains its beta-gamma configuration but has decayed significantly. It
shall remain the target region for a further 24 hours although we are
ending the Major Flare Watch at this time. Additional intermediate
level activity is expected.
The position of NOAA 12887 on 31-Oct-2021 at 12:30 UT is:
S28W40, ( 549", -504" )

Dear Collaborators,
C-level activity from both NOAA 12887 and 12891 has continued since
the last message, with NOAA 12891 producing a C9.0 flare at 13:33 UT
today. The target region NOAA 12887 has retained its beta-gamma
configuration and maintains mixed polarities in its trailing portion.
Major Flare Watch shall remain in effect for a further 24 hours, with
a slight chance of an M5 flare or greater in the next 24 hours.
The position of NOAA 12887 on 29-Oct-2021 at 23:30 UT is:
S26W22, ( 326", -488" )

Dear Collaborators,
Solar activity remains high. The largest event since the last message
was an M1.5 flare from NOAA 12891 in the northeast quadrant. The
target region NOAA 12887 has remained relatively quiescent since the
X-class flare yesterday, and has continued to decay. It retains its
beta-gamma configuration, with signs of polarity mixing in its
trailing portion. Major Flare Watch shall remain in effect with chance
for an additional >M5 flare over the next 24 hours.
The position of NOAA 12887 on 29-Oct-2021 at 07:30 UT is:
S26W12, ( 181", -492" )

Dear Collaborators,
The target region NOAA 12887 has just produced an X1.0 flare at
beginning 15:17 UT today. At this time we are implementing a Major
Flare Watch due to the increased likelihood of another >M5 flare in
the next 24 hours.
The position of NOAA 12887 on 28-Oct-2021 at 15:30 UT is:
S26W05, ( 75", -494" )

Dear Collaborators,
Solar activity remains elevated although NOAA 12891 has remained
relatively quiescent. Much of the C-class activity over the past 24
hours, and the M1.4 flare at 07:30 UT today, has come from NOAA 12887.
This shall be the default target region once again. The region
currently has a beta-gamma configuration, but is showing signs of
decay as it crosses the central meridian. Further C-level activity
expected, with chance for an additional isolated M-class flare.
The position of NOAA 12887 on 28-Oct-2021 at 07:30 UT is:
S26W00, ( 0", -495" )

Dear Collaborators,
Solar activity continues at intermediate levels. The target region
along the northeast limb has now been designated as NOAA 12891, and
has produced some low C-level activity since the last message. Former
target region NOAA 12887 produced a C8.5 flare at 05:47 UT today. NOAA
12891 appears to be a compact beta region and shall continue as the
target region for a further 24 hours. Additional B- and C-level
activity possible.
The position of NOAA 12891 on 27-Oct-2021 at 11:30 UT is:
N20E71, ( -858", 304" )

Dear Collaborators,
Solar activity has increased significantly since the last message due
to a new active region currently behind the northeast limb. The region
has produced several high C-class flares over the past few hours as
well as an M1.3 flare at 02:40 UT today. While the magnetic
configuration is uncertain at this time, this shall be the new target
region. Further C-level activity is expected with chance for an
additional M-class activity as the region rotates into view.
The approximate position of the target region on 26-Oct-2021 at 07:30 UT is:
N14E85, ( -933", 226" )
