Dear Collaborators,
Numerous B-class flares were produced by the target region
NOAA 12792 and also NOAA 12793 (S16E57, alpha/A-type)
in the past 24 hours. 12792 also produced the largest event,
a C4.0, at 12/14/14:09 UT. 12792 remains its beta/B-type
configuration and continues to show opposite flux in its leading
portion. If possible, please also include NOAA 12793 in your
field of view. Additional B-class activities are expected, with a
chance of another C-class flare in the next 24 hours.
The position of NOAA 12792 on December 15 at 04:30 UT is:
S22E36 (-532", -353")

Dear Collaborators,
The target region NOAA 12792 was the source of a few
A-class and low B-class flares in the past 24 hours. 12792
remains its beta/B-type classification. It continues showing
flux emergence particularly in its northern portion. More
B-class activities are expected in the following 24 hours.
The position of NOAA 12792 on December 14 at 04:30 UT is:
S22E49 (-683", -357")

Dear Collaborators,
The target region has been designated as NOAA 12792, with
a beta/B-type configuration. 12792 has produced at least five
low B-class flares since the last message, the largest one being
a B2.3 at 12/12/20:29 UT. 12792 shows obvious flux emergence
around its center. B-class activities are expected with a slight
chance of a C-class event in the next 24 hours.
The position of NOAA 12792 on December 13 at 04:30 UT is:
S23E64 (-807", -376")

Dear Collaborators,
Numerous B-class X-ray events were produced by yesterday's target
NOAA 12790 (S23W71), NOAA 12791 (S15W44), as well as the east
limb region mentioned in the last message. The largest flare was a B6.7
at 12/12/01:01 UT from the east limb region, which will be today's target.
12790 (alpha/H-type) and 12791 (plage region) are rotating to the west
limb. B-class activities are expected with a chance of C-class events in
the next 24 hours.
The approximate position of the target on December 12 at 04:30 UT is:
S23E85 (-900", -430")

Dear Collaborators,
The plage region NOAA 12791 (S15W32) was the source of
a few B-class flares since the last message, the largest one
being a B5.8 at 12/11/00:50 UT. In addition, a B5.3 flare was
produced by an east limb region (S21E89). The target region
NOAA 12790 only showed some EUV jets in the past 24 hours.
12790 remains an alpha/H-type configuration and shows a flux
emergence as it is rotating to the west limb. We will watch
12790 for a further 24 hours; if possible, please also include
12791 in your field of view. B-class activities are expected in
the following 24 hours.
The position of NOAA 12790 on December 11 at 08:30 UT is:
S22W60 (783", -361")

Dear Collaborators,
Solar activity continues at a low level. The target region NOAA
12790 and the plage region NOAA 12791 were the sources of
a few A-class as well as low B-class flares in the past 24 hours.
12790 remains its alpha/H-type configuration. It shows some
small EUV jets. B-class events are probable in the next 24 hours.
The position of NOAA 12790 on December 10 at 08:30 UT is:
S23W47 (657", -377")

Dear Collaborators,
Solar activity has been at a low level since the last message. Only two
~B1 flares were produced by NOAA 12791 that has decayed to a plage
region. The only region with sunspots on the visible solar disk is NOAA
12790. 12790 remains its alpha/H-type configuration and has been flare
quiet since the C7.4 flare. B-class flares are probable with a slight chance
of an isolated C-class event in the next 24 hours.
The position of NOAA 12790 on December 9 at 04:30 UT is:
S21W32 (483", -347")

Dear Collaborators,
The target region NOAA 12790 was the source of a C7.4 flare
(at 12/07/15:46 UT) and also two ~B6 flares in the past 24 hours.
The C7.4 flare was associated with an Earth-directed halo CME.
12790 remains its alpha/H-type configuration and continues to
show mixed polarities in its intermediate portion. B-class flares
are expected with a chance of an isolated C-class event in the
following 24 hours.
The position of NOAA 12790 on December 8 at 04:30 UT is:
S22W18 (280", -365")

Dear Collaborators,
The largest X-ray event was a B8.3 flare (at 23:32 UT on December 6)
since the last message, which was produced by the target region NOAA
12790. NOAA 12791 (beta/B-type) also produced two B-class flares (a
B3.5 and a B3.6 on December 7). 12790 has been designated as an
alpha/H-type region and in its decay phase. We will watch this region for
a further 24 hours. B-class flares are expected in the next 24 hours.
The position of NOAA 12790 on December 7 at 04:30 UT is:
S23W05 (78", -383")

MM#009 Default Target
Dear Collaborators,
Target region 2790 (H-type/alpha) was the source of two
C-class events since the last message. The largest was
a C1.6 at 12/06/13:27 UT. Both events were associated
with the activation/eruption of the very dynamic small
filament located along the region's U-shaped main magnetic
inversion line. B-class events probable with another C-class
event possible in the next 24 hour period.
The position of NOAA 2790 on December 06 at 15:00 UT is:
S24E06 (Solar X = -093", Solar Y = -400")
