Dear Collaborators,
NOAA 12894 has remained quiescent since the last message, although
solar activity has increased recently due to the emergence of a new
bipolar region in the northeast quadrant. The region is currently
unnumbered but has produced several B-class flares as well as two C1
flares over the last 24 hours. This shall be the new target region
with further low-to-intermediate level activity possible.
The approximate position of the target region on 8-Nov-2021 at 12:30 UT is:
N25E57, ( -740", 379" )

Dear Collaborators,
Solar activity is at a very low level. Target region NOAA 12894
emerged some additional small sunspots in its trailing polarity
flux and is now classified as a beta/C-type sunspot group. This
region has continued producing B-class activity since the last
message, remaining as the most active NOAA region on the visible
disk. More B-class activity is expected over the next 24 hours,
with a small chance for an isolated C-class flare.
The position of NOAA 12894 on 7-Nov-2021 at 18:30 UT is:
S27E45 , ( -613", -479" )

Dear Collaborators,
The level of solar activity is low. The target region has been
designated as NOAA 12894 and was classified as an alpha/H-type
sunspot group at the start of the UT day. Since then 12894 has
formed a small trailing-polarity spot and a leading-polarity
spot in its interior. NOAA 12894 has continued producing many
B-class flares and three C-class flares since the last message
- the largest being a C2.3 on 5-Nov-2021 at 21:36 UT. High
B-class activity is expected in the following 24-hour period,
with a good chance for additional C-class flares.
The position of NOAA 12894 on 6-Nov-2021 at 17:00 UT is:
S27E57 , ( -724", -470" )

Dear Collaborators,
Solar activity is at a low level. NOAA 12891 has continued to decay
since the last message, and was reclassified as a beta-delta/C-type
sunspot group. Although the delta is small, NOAA 12891 produced the
largest flare of the period (a C1.6 on 5-Nov-2021 at 15:21 UT). The
target region has rotated onto the visible disk to display a mature
leading polarity spot and no trailing polarity spots so far, but it
has not yet been designated a NOAA number. This region appears to
have a beta/H-type sunspot classification and has been the source
of many B-class flares since the last message (the largest being a
B9.5 on 5-Nov-2021 at 15:50 UT). This currently unnumbered region
remains as the target region because of NOAA 12891's decay. Further
B-class activity is expected over the next 24 hours, with a chance
for a C-class flare.
The approximate position of this region on 5-Nov-2021 at 20:00 UT is:
S27E69 , ( -806", -460" )

Dear Collaborators,
The level of solar activity is low. Target NOAA 12891 has decayed
since the last message, decreasing in sunspot area and number of
spots but remains classified as a beta/D-type sunspot group. This
region has also only produced one B-class flare since its C5.2 on
3-Nov-2021. A new region is currently rotating over the South East
limb and has been the source of two C-class flares, including the
largest event of the period - a C3.5 flare on 4-Nov-2021 at 10:34
UT (that was likely foot-point occulted). This new region becomes
the target region. C-class flares are likely in the following 24-
hour period, with a small chance for an M-class flare.
The approximate position of this region on 4-Nov-2021 at 19:00 UT is:
S28E90 , ( -854", -453" )

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" )
