Dear Collaborators,
Solar activity has been at intermediate levels since the
last message. The target region NOAA 13372 produced
11 C-class flares in the period, the largest one being a
C9.4 flare at 07/13/05:05 UT. 13372 has been designated
as a beta/E-type configuration. NOAA 13361 (N25W69,
beta-gamma/D-type) also produced several C4 or C5 flares.
Today we will continue the Major Flare Watch campaign.
Further C-class flares are expected with still a chance of
major flares in the next few days.

Dear Collaborators,
Solar activity has been at a high level since the last message.
The northeast limb region mentioned in the previous message
was designated as NOAA 13372 and has produced three major
flares (an M6.8 at 07/11/17:51 UT, an M5.8 at 07/11/22:04 UT,
and an M6.9 at 07/12/08:49 UT), four low M-class flares, and six
C-class flares. Now we are implementing the Major Flare Watch
campaign. Another three regions, NOAA 13368, 13366, and
13361 also produced three low M-class flares. Low M-class
activities are expected with a good chance of additional above
M5 flares in the next few days.

Dear Collaborators,
The largest event since the last message was an M1.5
produced by NOAA 13358. 13358 also produced more
than five C-class flares in the period. Today the target
will switch to this region, although it rotates over the
west limb. 13358 is still emerging with new magnetic
fluxes. Yesterday's target region NOAA 13361 was the
source of only two low C-class flares and remains a beta-
gamma-delta/E-type configuration. Please note that a
northeast limb region (N22E88) produced about ten C-class
flares (the largest one being a C8.0) before it rotates on
the visible disk. Further C-class activities are expected
with a chance of a low M-class flare in the next 24 hours.

Dear Collaborators,
Solar activity has been at an intermediate level since the last
message. The largest event in the period was an M2.4 flare
at 07/10/03:29 UT from NOAA 13358 that has an alpha/A-type
sunspot group. Multiple C-class flares were produced by various
regions, including NOAA 13358, 13368, 13366, 13367, and
13361, with the largest one being a C9.4 at 07/10/01:49 UT from
the target region NOAA 13361. 13361 has been designated as
a beta-gamma-delta/E-type configuration. We will watch this region
for a further 24 hours. Additional C-class flares are expected from
various regions with a good chance for a low M-class flare in the
next 24 hours.

Dear Collaborators,
Solar activity has continued at the C-level since the last message,
the largest event being a C5.7 flare from NOAA 13366 at 00:05 UT
today. NOAA 13361 has also remained active and shall continue as the
target region. It retains its beta-delta configuration and shows signs
of further development. Sustained intermediate level activity likely
over the next 24 hours.
The position of NOAA 13361 on 9-Jul-2023 at 11:30 UT is:
N24W19, ( 281", 331" )

Dear Collaborators,
Solar activity has continued at the low C-level since the last
message, although NOAA 13359 has remained quiescent and shown signs of
decay. Much of the activity has come from NOAA 13361 in the northern
hemisphere, which is now classified as a beta-delta/E-type region and
continues to develop. NOAA 13361 shall be the new default target
region with further intermediate level activity expected over the next
24 hours.
The position of NOAA 13361 on 8-Jul-2023 at 15:30 UT is:
N24W07, ( 105", 330" )

Dear Collaborators,
NOAA 13354 has now rotated beyond the western limb. A large (~400uh)
alpha sunspot, designated NOAA 13363, has rotated into view on the
southeast limb but has so far remained quiescent. The new target
region shall be NOAA 13359, a beta/D-type active region in the
southwest quadrant. It has been the source of several C-class flares
since the last message, as well as an M4.0 flare at 06:17 UT today.
Further intermediate level activity likely over the next 24 hours.
The position of NOAA 13359 on 7-Jul-2023 at 11:30 UT is:
S21W22, ( 331", -388" )

Dear Collaborators,
Solar activity has continued at intermediate levels with NOAA 13354
now behind the northwest limb. The region has produced two partially
occulted M1 flares since the last message and shall remain the target
region for a further 24 hours, although we are ending the Major Flare
Watch campaign at this time. Further C-level activity possible with
slight chance of an isolated low M-class flare.
The approximate position of NOAA 13354 on 6-Jul-2023 at 11:30 UT is:
N15W90, ( 911", 243" )

Dear Collaborators,
NOAA 13354 is now on the northwestern limb and has continued to
produce C-level activity since the M1.5 flare yesterday. It remains
classified as a beta-gamma-delta region although its precise size and
magnetic configuration are uncertain at this time. We shall continue
with the Major Flare Watch campaign in effect for a further 24 hours
due to the possibility of an >M5 flare before the region rotates
behind the western limb.
The position of NOAA 13354 on 5-Jul-2023 at 07:30 UT is:
N16W91, ( 906", 260" )

Dear Collaborators,
Solar activity has continued at the C-level since the X-class flare
from NOAA 13354 two days ago with events from multiple regions across
the visible solar disk. An M1.4 flare from the target region is also
currently in progress. The region retains its beta-gamma-delta
configuration as it approaches the northwestern limb and the Major
Flare Watch campaign shall remain in effect due to the possibility of
an >M5 flare before west limb transit.
The position of NOAA 13354 on 4-Jul-2023 at 11:30 UT is:
