Dear Collaborators,
Solar activity continues at intermediate levels. NOAA 13141 was the
source of several C-class flares and another two M1 flares since the
last message. It retains its beta-gamma-delta configuration but
appears to be in decay. Meanwhile, NOAA 13140 to the northwest has
shown signs of rapid flux emergence. Major Flare Watch shall remain in
effect for a further 24 hour due to the increased possibility of an
>M5 flare. NOAA 13141 shall continue as the target region but keep
NOAA 13140 in your field of view as well if possible.
The position of NOAA 13141 on 12-Nov-2022 at 12:30 UT is:
N14W21, ( 338", 186" )

Dear Collaborators,
Solar activity has increased since the last message, with NOAA 13141
producing several C-class flares as well as an M1.2 flare at 07:00 UT
today as it crossed the central meridian. The region has undergone
significant flux emergence and is now classified as a beta-gamma-delta
region with an area of 600uH. In particular, there has been negative
polarity emergence to the north and west of the positive polarity
leader spot. As such, we are reimplementing the Major Flare watch
campaign, at this time. Further intermediate level activity likely
with chance for an >M5 flare in the next 24-48 hours.
The position of NOAA 13141 on 11-Nov-2022 at 08:30 UT is:
N15W06, ( 98", 197" )

Dear Collaborators,
Solar activity continues at low levels. NOAA 13141 has continued to
produce ~C1 flares since the last message. There was also a C4.3 flare
from a spotless region in the southeast quadrant at 19:46 UT
yesterday. NOAA 13141 retains its beta-gamma configuration, and shall
continue as the target region as it approaches the central meridian,
although we shall end the Major Flare Watch at this time. Further low
level events likely over the next 24 hours.
The position of NOAA 13141 on 10-Nov-2022 at 12:30 UT is:
N14E06, ( -98", 179" )

Dear Collaborators,
Solar X-ray flux has remained steady below the C1 level. NOAA 13141
has remained relatively quiescent since the M5.2 flare on 6-Nov-2022.
However, the region has increased in both size and complexity since
the last message and is now classified as a beta-gamma region. NOAA
13141 shall continue as the target region with a Major Flare Watch in
effect for another 24 hours.
The position of NOAA 13141 on 9-Nov-2022 at 12:30 UT is:
N14E18, ( -291", 179" )

Dear Collaborators,
NOAA 13141 in the northeast has remained unchanged in terms of size
and complexity since the last message. It was the source of a
long-duration C3.1 flare at 13:16 UT yesterday, but has been otherwise
quiescent. It shall remain the target region with a Major Flare Watch
in effect due to the increased possibility of an >M5 flare over the
next 24 hours.
The position of NOAA 13141 on 8-Nov-2022 at 00:30 UT is:
N15E37, ( -564", 202" )

Dear Collaborators,
Solar activity has increased over the past 24 hours with an M5.2 flare
from NOAA 13141 at 23:59 UT yesterday. The region is currently
classified as a beta/E-type region with an area of 460uH, but is
showing signs of mixed polarity within the positive leader spot. NOAA
13141 shall continue as the target region, although we are issuing a
Major Flare Watch alert at this time due to the increased possibility
of another >M5 flare within the next 24-48 hours.
The position of NOAA 13141 on 7-Nov-2022 at 12:30 UT is:
N15E44, ( -651", 206" )

Dear Collaborators,
Solar activity has been at a very low level. There are seven regions
with sunspots on the visible solar disk, but most of them have been
flare quiet. The target region NOAA 13141 was the source of a C1.2
flare at 11/06/01:10 UT (the largest one of the period) plus several
high B-class events. 13141 has been designated as a beta/D-type
region with an increase in the sunspot area and number of spots.
It is showing mixed polarities in its leading portion. Additional C-class
activities are expected in the next 24 hours.
The position of NOAA 13141 on November 6 at 08:30 UT is:
N14E58 (-797", 200")

Dear Collaborators,
The limb target region has been numbered as NOAA 13141
with an Alpha/H-type configuration. 13141 produced two low
C-class flares (a C1.7 at 11/04/22:13 UT and a C1.5 at
11/04/18:47 UT) and also a few high B-class flares. This region
appears to be showing a magnetic flux emergence as it rotates
onto the visible solar disk. Further C-class activities are expected
in the next 24 hours.
The position of NOAA 13141 on November 5 at 08:30 UT is:
N15E70 (-879", 228")

Dear Collaborators,
The largest event since the last message was a C5.6 flare
at 11/04/07:13 UT produced by a northeast limb region. This
region has some sunspots as rotating onto the visible disk and
we will watch this region today. Yesterday's target NOAA 13135
was classified as a beta/D-type region again and has been flare
quiet for more than one day. An additional high C-class flare is
probable in the next 24 hours.
The approximate position of the target on November 4 at 13:30 UT is:
N14E89 (-940", 270")

Dear Collaborators,
Solar activity continues at a very low level. The largest event
since the last message was a C1.4 flare at 11/03/06:58 UT
produced by NOAA 13136 that was classified as a beta/D-type
region. 13136 also produced another C1 flare plus two high
B-class flares. This region has been losing its spots. The target
region NOAA 13135 was the source of two ~C1 flares during
the period. It has been designated as a beta/E-type region (again).
Only high B-class and low C-class activities are expected in the
next 24 hours.
The approximate position of NOAA 13135 on November 3 at 16:15 UT is:
N26W07 (100", 360")
