Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13341 has
been quite stable in terms of number of spots and spot area since
the last message, but has decreased in its designation of magnetic
complexity to a beta/C-type sunspot group. NOAA 13341 remained the
most flare-productive region, being the source of multiple C-class
flares and the largest magnitude flare in the period - another M1.1
on 22-Jun-2023 at 10:57 UT. NOAA 13341 will continue as the MM#003
Major Flare Watch target for at least another 24 hours. Further low
M-class flares are probable in the next 24 hours, with a chance for
an isolated >M5 or X-class flare.
The position of NOAA 13341 on 22-Jun-2023 at 18:00 UT is:
S15E38 , ( -564", -268" )

Dear Collaborators,
The level of solar activity is moderate-to-high. Target NOAA 13341 has
matured since the last message without significant change in number of
spots or spot area, increasing in magnetic complexity to be classified
as a beta-gamma/D-type sunspot group. NOAA 13337, a previously decayed
region that is emerging new spots, produced an M1.0 flare in the period
(on 21-Jun-2023 at 15:31 UT) but NOAA 13341 continued to be the most
flare-productive region with being the source of several C-class flares
and the largest magnitude flare in the period - an M1.1 on 21-Jun-2023
at 12:31 UT. The MM#003 Major Flare Watch will continue on NOAA 13341.
Additional low M-class flares are probable over the following 24-hour
period, with a chance for another >M5 or X-class flare.
The position of NOAA 13341 on 21-Jun-2023 at 18:00 UT is:
S15E48 , ( -680", -264" )

Dear Collaborators,
Solar activity is at a high level. The target limb region has rotated on
disk and has been designated as NOAA 13341, a beta/C-type sunspot group
at the start of the UT day. Although NOAA 13342 (that is rotating up to
the South West limb) has also produced M-class events, the target remains
on NOAA 13341 and we are initiating a MM#003 Major Flare Watch. This is
because 13341 has just produced an X1.1 flare on 20-Jun-2023 at 16:42 UT.
Further M-class flares are expected in the next 24 hours, with a chance
for another >M5 or X-class flare.
The position of NOAA 13341 on 20-Jun-2023 at 18:00 UT is:
S13E52 , ( -727", -229" )

Dear Collaborators,
The level of solar activity is low-to-moderate. Target region NOAA 13335
has been stable in spot area and number of spots since the last message,
remaining classified as a beta-gamma/E-type sunspot group. A new region
is in the process of rotating over the South East limb and already shows
spots. This currently unnumbered region has already produced four C-class
and two M-class flares (an M1.4 and an M1.2 on 19-Jun-2023 at 03:37 UT
and 12:06 UT, respectively) that were the largest flares in the period.
The target switches to this new limb region. Additional C-class activity
is expected over the following 24-hour period, with a chance for M-class
flares.
The approximate position of this region on 19-Jun-2023 at 15:00 UT is:
S12E90 , ( -911", -196" )

Dear Collaborators,
Solar activity remains unchanged since the last message. There have
been several low C-class flares from multiple regions as well as an
M1.3 flare from NOAA 13336 at 00:25 UT today. NOAA 13335 retains its
beta-gamma/E-type configuration and shall continue as the target
region. Further low-to-intermediate level activity expected from both
it and NOAA 13336 over the next 24 hours.
The position of NOAA 13335 on 18-Jun-2023 at 11:30 UT is:
S15E17, ( -267", -266" )

Dear Collaborators,
Solar activity continues at intermediate levels. There were M1 flares
from both NOAA 13331 and NOAA 13338 since the last message. NOAA 13335
and NOAA 13336 have continued to produce C-class flares, and NOAA
13335 has now developed to a beta-gamma region. It shall remain the
target region with further intermediate level activity likely. Also
include NOAA 13336 in your field of view if possible.
The position of NOAA 13335 on 17-Jun-2023 at 11:30 UT is:
S15E30, ( -457", -262" )

Dear Collaborators,
Solar activity is at intermediate levels with M1 flares from both NOAA
13327 and NOAA 13328 since the last message, while NOAA 13335 and NOAA
13336 have been relatively quiescent. However, NOAA 13335 has
undergone significant development increasing in both size and
complexity and shall be the new target region. Possibility of high
C-/low M-level activity over the next 24 hours. Also include NOAA
13336 in your field of view if possible.
The position of NOAA 13335 on 16-Jun-2023 at 11:30 UT is:
S15E44, ( -635", -258" )

Dear Collaborators,
The region near the southeast limb has now been identified as two
separate regions: NOAA 13335 and NOAA 13336. Both have been the source
of C-level activity since the last message, including a C9.7 flare at
12:33 UT today from NOAA 13336, and both have been classified as beta
regions with comparable sunspot areas. NOAA 13336 shall be the new
default target region but also include NOAA 13335 in your field of
view if possible. Further C-level activity likely with chance for an
isolate low M-class flare.
The position of NOAA 13336 on 15-Jun-2023 at 11:30 UT is:
S20E59, ( -762", -331" )

Dear Collaborators,
NOAA 13327 has now completely decayed. Low C-level activity continues
from newly-emerged NOAA 13333 and an unnumbered region near the
southeast limb. The unnumbered region shall be the new target region
as it appears to be more dynamic than NOAA 13333 and may have an
extended quadrupolar configuration. Further intermediate level
activity possible over the next 24 hours as it rotates into view.
The approximate position of the target region on 14-Jun-2023 at 11:30 UT is:
S20E81, ( -876", -325" )

Dear Collaborators,
There has been a slight resurgence of activity from NOAA 13327 since
the last message, including two ~C5 flares at 23:16 UT yesterday and
11:57 UT today. The region continues to decay significantly in terms
of size and complexity and is now classified as a simple beta region.
There is also a large filament channel just to the south of the active
region. NOAA 13327 shall continue as the target region for a further
24 hours with additional low level activity possible. Chance for a
larger event if the filament becomes unstable.
The position of NOAA 13327 on 13-Jun-2023 at 11:30 UT is:
S15W47, ( 669", -253" )
