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")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2866 is rapidly decaying and mostly
quiescent since the last message. NOAA 2868 (S19W57)
is also decaying and quiet. Both 2866 and 2868 have about
the same potential to produce C-class events therefore, if possible,
include both regions within the FOV. B-class activity likely with the
chance of an isolated C-class event in the next 24 hour period.
The position of NOAA 2866 on September 12 at 14:45 UT is:
S18W40 (Solar X =585", Solar Y = -381")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2866 has significantly decayed
especially within its trailing portion. There is weak
mixed polarities located in the region's intermediate
area. 2866 was only able to produce a couple of
minor B-class events since the last message.
New flux is emerging in the northern portion of
NOAA 2868 (S20W43). 2868 produced two C1 events
in the past 24 hours. The primary target will continue
to be 2866 for at least today but, if possible, include
2868 within your FOV. C-class events possible with
a slight chance of an isolated M-class event in the
next 24 hour period.
The position of NOAA 2866 on September 11 at 14:00 UT is:
S17W26 (Solar X = 401", Solar Y = -381")

MM#009 Default Target
Dear Collaborators,
Target region 2866 remains a large compact active region
with weak polarity mixing within its narrow intermediate
portion but was only able to produce one minor B-class
event since the last message, A C-class event possible
with a slight chance of an isolated M-class event in the
next 24 hour period.
The position of NOAA 2866 on September 10 at 14:00 UT is:
S17W13 (Solar X = 206", Solar Y = -390")

MM#009 Default Target
Dear Collaborators,
Target region NOAA 2866 is mostly unchanged since
the last message. 2866 was the source of three B-class
events and an isolated C-class event. The largest events
were a C3.5 at 09/09/08:31 UT and a B8.1 at 09/09/17:16 UT.
B-class events expected with another C-class event likely
with a chance of an isolated M-class event in the next 24
hour period.
The position of NOAA 2866 on September 09 at 17:00 UT is:
S17W01 (Solar X = 015", Solar X = -393")
