Dear Collaborators,
The level of solar activity is moderate-to-high. Target NOAA 12860
has maintained number of spots and spot area, remaining classified
as a beta-gamma/E-type sunspot group. NOAA 12860 has continued to
produce multiple C-class flares since the last message, including
a C7.4 flare and a C8.1 flare (the largest flare of the period) on
29-Aug-2021 at 00:24 UT and 09:54 UT respectively. Further C-class
flares are expected in the following 24-hour period with the Major
Flare Watch remaining in effect since NOAA 12860 has the potential
for M-class activity.
The position of NOAA 12860 on 29-Aug-2021 at 15:00 UT is:
S29W18 , ( 257", -557" )

Dear Collaborators,
Solar activity has increased significantly since the last message. The
target region NOAA 12860, now along the central meridian, has produced
several C-class flares and an M4.7 flare is currently in progress. We
are therefore implementing a Major Flare Watch campaign at this time.
The region has increased in size and is now classified as a beta-gamma
region. Further intermediate level activity expected over the next 24
hours with chance for a >M5 flare.
The position of NOAA 12860 on 28-Aug-2021 at 03:30 UT is:
S28E01, ( -14", -548" )

Dear Collaborators,
The target region NOAA 12860 was the source of several B-class flares
since the last message, as well as a C3.9 flare at 23:17 UT yesterday.
Former target NOAA 12859 also produced a C3.0 flare at 17:48 UT
yesterday. NOAA 12860 remains largely unchanged in terms of size and
complexity as it approaches the central meridian. Further B- and
C-level activity anticipated over the next 24 hours.
The position of NOAA 12860 on 27-Aug-2021 at 11:30 UT is:
S30E07, ( -100", -573" )

Dear Collaborators,
Solar activity has continued at the B-level with events from NOAA
12859, NOAA 12860, and a new ERF in the northeast quadrant. NOAA 12860
has continued to develop and shall remain the target region. The
region retains its beta configuration but continues to undergo flux
emergence in its core. Further B-level activity likely with chance for
an isolated C-class flare.
The position of NOAA 12860 on 26-Aug-2021 at 11:30 UT is:
S27E21, ( -304", -526" )

Dear Collaborators,
NOAA 12859 was the source of a C1.5 flare at 14:18 UT yesterday but
has since decayed to an alpha region. A large, rapidly emerging region
in the southeast quadrant was also the source of a C1 flare at 01:10
UT yesterday and shall be the new target region. The region is
designated as NOAA 12860 and has a beta/B-type configuration. Further
B- and C-level activity likely from the new target region over the
next 24 hours as it continues to develop.
The position of NOAA 12860 on 25-Aug-2021 at 11:30 UT is:
S28E34, ( -469", -528" )

Dear Collaborators,
Solar activity has continued at low levels since the last message.
NOAA 12859 remains the source of low B-level activity, including a
B8.8 flare at 12:03 UT today. The region remains unchanged in terms of
size and complexity, and shall continue as the target region for the
next 24 hours. Further B-level activity possible, as well as a chance
for a C-class flare.
The position of NOAA 12859 on 24-Aug-2021 at 11:30 UT is:
N19E39, ( -566", 222" )

Dear Collaborators,
Solar activity continues at low levels. NOAA 12859 in the northeast
quadrant has continued to produce B-level activity since the last
message, but remains largely unchanged. It retains its beta
configuration and shall continue as the target region. Further B-level
activity possible with chance for an isolated C-class flare.
The position of NOAA 12859 on 23-Aug-2021 at 11:30 UT is:

Dear Collaborators,
Solar activity is at a low level. The target region has now been designated
as NOAA 12859 and classified as a beta/C-type sunspot group. NOAA 12859 has
continued to produce multiple B-class flares since the last message as well
as three C-class flares, the largest of which was a C1.9 on 22-Aug-2021 at
10:16 UT. Further B-class flares are expected over the next 24 hours, with
a good chance for low-to-mid C-class flares.
The position of NOAA 12859 on 22-Aug-2021 at 22:00 UT is:
N20E60 , ( -774", 269" )

Dear Collaborators,
The level of solar activity is very low. The target region has rotated
further on disk. Although the main leading polarity spot can be seen to
be displaying a light bridge, this region remains too close to the limb
for accurate classification. The target region has continued to produce
B-class flares since the last message, the largest of which was a B4.9
on 21-Aug-2021 at 11:28 UT. Further B-class activity is expected in the
following 24-hour period, with a chance for additional C-class flares.
The approximate position of this region on 21-Aug-2021 at 22:00 UT is:
N20E74 , ( -857", 292" )

Dear Collaborators,
Solar activity is at a low level. Yesterday's target region has begun
rotating over the North East limb with its main leading polarity spot
coming into view. This region has produced multiple B-class and three
C-class events since the last message, including the largest flare of
the period (a C3.0 on 20-Aug-2021 at 15:50 UT), all of which are still
footpoint occulted by the North East limb. Further C-class flares are
expected over the next 24 hours.
The approximate position of this region on 20-Aug-2021 at 22:00 UT is:
N20E90 , ( -891", 322" )
