Dear Collaborators,
NOAA 13089 has continued to produce C-level activity since the last
message, the largest of which was a C3.8 flare at 17:04 UT yesterday.
The region is currently classified as a beta-gamma/E-type region with
a sunspot area of 350uh. Further C-level activity likely as the region
approaches the southwest limb.
The position of NOAA 13089 on 3-Sep-2022 at 11:30 UT is:
S23W53, ( 700", -435" )

Dear Collaborators,
Solar activity has continued at the low C-level. NOAA 13089 remains
largely unchanged in terms of size and complexity, and has produced
several C1 flares since the last message. The new active region on the
eastern limb has been designated as NOAA 13092 and also produced some
~C1 flares. NOAA 13089 shall continue as the target region with
further C-level activity likely.
The position of NOAA 13089 on 2-Sep-2022 at 11:30 UT is:
S22W40, ( 568", -439" )

Dear Collaborators,
Solar activity from NOAA 13089 has remained steady at the C1 level
since the last message, although a new unnumbered region rotating onto
the eastern limb was the source of a C4 flare at 13:46 UT today. NOAA
13089 has reestablished its beta-gamma-delta configuration due to
polarity mixing in its trailing spot and has begun to increase in size
once again. It shall continue as the target region with further
C-level activity likely over the next 24 hours.
The position of NOAA 13089 on 1-Sep-2022 at 11:30 UT is:
S22W27, ( 401", -453" )

Dear Collaborators,
Solar activity has returned to intermediate levels now that NOAA 13088
is behind the southwestern limb. The region produced a long-duration
M2.1 flare at 18:04 UT yesterday before parting. NOAA 13089 has been
downgraded to a beta-gamma region and has halved in size since the
last message. It shall be the new target region with further C-level
activity expected over the next 24 hours.
The position of NOAA 13089 on 31-Aug-2022 on 11:30 UT is:
S22W13, ( 198", -462" )

Dear Collaborators,
Solar activity has diminished in the past 24 hours with NOAA 13088 now
beyond the western limb. The region produced five M-class flares since
the last message, including an M4.7 around 17:00 UT yesterday. NOAA
13089 along the central meridian is now classified as a
beta-gamma-delta region with an area of >500uh but is largely
quiescent. The looptops of NOAA 13088 on the southwest limb shall
remain the target region but we will be ending the Major Flare watch
campaign at this time. Only intermediate level activity expected.
The position of NOAA 13088 on 30-Aug-2022 at 11:30 UT is:
S27W91, ( 845", -425" )

Dear Collaborators,
Solar activity remains at high levels with NOAA 13088 having produced
an M8.6 flare at 10:48 UT today, as well as two other mid-M flares
since the last message. The region is now located behind the southwest
limb and its size and magnetic configuration are no longer known.
However it shall remain the target region with a Major Flare Watch in
effect. Chance remains for an additional >M5 flare in the next 24
hours.
The position of NOAA 13088 on 29-Aug-2022 at 11:30 UT is:

Dear Collaborators,
Solar activity has been at a moderate to high level since
the last message. The largest event of the period was an
M6.7 flare at 08/28/15:48 UT produced by NOAA 13088.
13088 also produced four low M-class flares with the largest
one being an M1.8 at 08/27/15:45 UT. Today the Major
Flare Watch region will switch to NOAA 13088, though it
is rotating beyond the west limb. This region was designated
as a beta-gamma/D-type configuration. Additional M-class
flares are probable in the next 24 hours.
The position of NOAA13088 on August 28 at 15:30 UT is:
S27W82 (837", -442")

Dear Collaborators,
Solar activity has been at a high level for the past 24 hours.
The target region NOAA 13089 was the source of two major
flares, an M7.2 at 08/26/12:08 UT and an M5.3 at 08/26/12:24 UT.
Moreover, NOAA 13088 (S28W62) produced 5 low M-class
flares, the largest one being an M4.8 at 08/27/01:52 UT. Today
we will implement the Major Flare Watch campaign. The target
region 13089 has been designated as a beta-gamma/D-type
configuration. 13088 has a beta/D-type sunspot group but
significantly increases the sunspot area. More low M-class
activities are expected with a chance of additional major flares
from these two regions.
The position of NOAA13089 on August 27 at 07:30 UT is:
S21E40 (-571", -422")

Dear Collaborators,
Solar activity increased further in the past 24 hours. The two
unnumbered active regions mentioned in the last message have
been designated as NOAA 13088 and 13089 (target region),
both of which have a beta/D-type sunspot group. These two
regions were the sources of numerous (about 20) C-class flares
and in particular, the target region NOAA 13089 produced three
low M-class flares, an M1.8 (08/25/19:39 UT), an M1.0 (08/25/23:21 UT),
and an M2.1 (08/26/10:41 UT). Both regions show an opposite
flux emerging in the core. Additional M-class flares are probable
in the next two days.
The position of NOAA13089 on August 25 at 07:30 UT is:
S24E52 (-684", -449")

Dear Collaborators,
Solar activity has slightly increased since the last message.
There were numerous B- and low C-class flares produced by
two unnumbered regions, one near the east limb (S23E64)
and the other rotating to the west limb (S27W41). The former
region produced the largest event of the period, a C3.6 at
08/25/09:53 UT. Today the target will switch to this region,
which seems to be emerging with new magnetic fluxes.
Yesterday's region NOAA 13085 has been flare quiet, though
it still has a beta/D-type sunspot group. Further C-class activities
are expected from the above two unnumbered regions in the
next 24 hours.
The approximate position of the target region on August 25 at 11:30 UT is:
S23E64 (-800", -400")
