Dear Collaborators,
The target region NOAA 12871 is producing an ~M3 flare! It also
produced the only C1.1 flare and numerous B-class flares in the
past 24 hours. 12871 retains its beta-delta/D-type configuration
while decreasing in the sunspot area. There appear another four
regions (NOAA 12872-12875) with sunspots on the visible solar disk,
which also produced a few B-class flares. Further B- and C-class
events are expected with some chance of additional M-class flare
in the next few days.
The position of NOAA 12871 on September 23 at 03:30 UT is:
S28E23 (-330", -542")

Dear Collaborators,
The largest event since the last message was a C1.8 flare
at 09/21/11:43 UT produced by NOAA 12873 which had a beta/
D-type magnetic configuration. 12873 also produced another
C1.1 flare and four B-class flares. The target region NOAA 12871
was the source of more than ten B-class flares as well as a C1.1
at 09/21/18:18 UT. 12871 has been designated as a Beta-Delta/
D-type region. Further B- and C-class events are expected with
a chance of a low M-class flare in the next few days.
The position of NOAA 12871 on September 22 at 03:30 UT is:
S27E34 (-477", -518")

Dear Collaborators,
The target region NOAA 12871 was the source of numerous
B-class flares (the largest one being a B6.3 at 09/20/10:38 UT)
in the past 24 hours. 12871 retains its beta/D-type configuration
but increases in the sunspot area and number of spots. There
also emerged two regions with sunspots, numbered as NOAA
12872 (N17E40, beta/C-type) and 12873 (N26W09, beta/B-type),
which were relatively flare quiet. More B-class events are expected
with a chance of C-class flares from the target region in the next
24-hour period.
The position of NOAA 12871 on September 21 at 03:30 UT is:

Dear Collaborators,
The target region has been numbered as NOAA 12871 with a
beta/D-type configuration. In the past 24 hours, 12871 produced
numerous low B-class flares as well as a B8.1 at 09/20/09:24 UT.
It shows flux emergence in its north portion. B-class activities are
expected with a chance of C-class flares in the next 24 hours.
The position of NOAA 12871 on September 20 at 07:30 UT is:

Dear Collaborators,
The limb target region was the source of four B-class flares
as well as two C-class flares (a C2.6 at 09/18/08:18 UT and
a C1.6 at 09/19/01:04 UT) in the past 24 hours. This region
has some sunspots now and is supposed to be numbered as
a new region tomorrow. It is still too close to the limb to ascertain
its magnetic configuration. Further B- and C-class activities are
expected in the next 24 hours.
The approximate position of the target region on September 19 at 07:30 UT is:
S32E77 (-800", -530")

Dear Collaborators,
The limb target region was the source of three low B-class flares (the
largest one being a B2.0 at 09/18/00:37 UT) in the past 24 hours. This
region is rotating onto the visible solar disk. Currently the visible solar
disk is still void of sunspots. B-class flares are expected and C-class
activities are probable from the limb target region in the next 24 hours.
The approximate position of the limb target on September 18 at 05:00 UT is:
S30E85 (-880", -410")

Dear Collaborators,
NOAA 12866/12868 has rotated beyond the west limb. Today the target
will switch to a new region near the east limb. This region has produced
a B2.3 flare as well as a C3.5 just in the past two hours. Further B- and
C-class activities are expected with a chance of an M-class flare if this
region had a complex magnetic configuration.
The approximate position of the limb target on September 17 at 05:00 UT is:
S30E85 (-880", -400")

Dear Collaborators,
NOAA 12868 produced a few low B-class flares in the past 24 hours.
12868 has rotated over the west limb, but the nearby region NOAA 12866
can still be seen, which has an alpha/H-type configuration. We will watch
this limb region for one more day. If possible, please also include the plage
region NOAA 12869 (S19W77) that was the source of two low B-class flares.
B-class activities are expected in the next 24 hours.
The position of NOAA 12866 on September 15 at 07:30 UT is:
S18W75 (876", -322")

Dear Collaborators,
The target region NOAA 12868 was the source of four B-class flares
as well as a C1.1 flare (at 09/14/06:40 UT) since the last message.
12868 has decayed to a beta/C-type configuration and is rotating over
the west limb. Another region NOAA 12869 was also produced two
low B-class flares but now decayed to a plage region. If possible,
please also include the region NOAA 12866 (S19W64, beta/D-type)
in your field of view. B-class activities are expected with a chance of
an isolated C-class flare in the next 24 hours.
The position of NOAA 12868 on September 14 at 07:30 UT is:
S20W81 (885", -341")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2866 (S18W53) continues to decay
and was quiescent in the past 24 hour period. We will
switch to NOAA 2868 today. 2868 was the source of
numerous B-class events. The largest was a B8.0
at 09/13/02:58 UT. Include both regions, if possible,
within the FOV. An isolated C-class event is possible
in the next 24 hours.
The position of NOAA 2868 0n September 13 at 15:30 UT is:
S20W71 (Solar X = 847", Solar Y = -360")
