MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region (now numbered NOAA 2242) was the
source of an isolated M1.6 event at 12/14/19:33 UT.
2242 also produced numerous C-class events. 2242
has a D-type/beta-gamma "self-contained" sunspot group.
The leading sunspot has an unusual E-W magnetic inversion
line and opposite polarity umbrae within a common penumbra but
they are located too far apart to be classified as a true delta
configuration. Emerging flux located in the trailing spots might
be forming a small delta. C-class events expected with the
chance of another M-class event in the next 24 hour period.
The position of NOAA 2242 on December 15 at 12:30 UT is:
S20E31 (Solar X = -473", Solar Y = -321")

Dear RHESSI Collaborators,
Solar activity is at a low to moderate level. Yesterday's target region, NOAA
12234, has not produced significant activity since the previous
message. On the other hand, a new region located at ~S10E70 was
responsible for the largest flare since the previous message, a
partially occulted M1.5 flare on 13-Dec-2014 at 5:13 UT. a series of
moderate to high C-class flares were also released. The region
contains a mixed polarity spot at its leading edge, showing a positive
spot surrounded by two negative spots. A new AR to the SE of NOAA
12237 has emerged, and shows a mixed polarity spot at the trailing
edge. The region was also responsible for a series of moderate to high
C-class events, but is also still actively emerging. Thus, the new AR
to the SE of NOAA 12237 is the target. Futher high C-class activity is
expected with the chance for an isolated low M-class flare.
The position of the new region on 14-Dec-2014 at 15:45 UT is:
S20E45 ( -650", -300" )

Dear RHESSI Collaborators,
Solar activity is at a low level. Yesterday's target region, NOAA
12234, was responsible for the largest event since the previous
message, a C4.0 flare on 12-Dec-2014 at 14:40 UT. The region exhibits
further signs of flux emergence, and now contains a small mixed
polarity spot in its leading portion. Further low C-class activity is
expected with the chance for an isolated high C-class flare.
The position of NOAA 12234 on 12-Dec-2014 at 16:35 UT is:
N04W07 ( 118",78" )

Dear RHESSI Collaborators,
Solar activity is at a low level. Yesterday's target region,
NOAA 12230, has released low C-class activity since
the previous message and shows signs of decay. On the
other hand, NOAA 12234 exhibits signs of flux emergence
and was responsible for the largest event, a C3.9 flare on
11-Dec-2014 at 8:56 UT. Further low C-class activity is
expected with the chance for an isolated high C-class flare.
The position of NOAA 12234 on 12-Dec-2014 at 00:35 UT is:
N04E03 ( -51", 76" )

Dear RHESSI Collaborators,
Solar activity is at a low to moderate level. The target region,
NOAA 12232, has not released significant activity since the
previous message. On the other hand, NOAA 12230 is under-
going rapid flux emergence, currently showing a gamma mag-
netic classification. It was responsible for a series of high C-
class activity, the largest event being a C8.6 flare on 9-Dec-
2014 at 10:24 UT. Further high C-class activity is expected
with a chance for an isolated M-class event.
The position of NOAA 12230 on 10-Dec-2014 at 16:35 UT is:
S14E12 ( -197", -231" )

Dear RHESSI Collaborators,
Solar activity is at a low level. The target region, NOAA
12222, released the largest event since the last message:
a C2.2 flare on 8-Dec-2014 at 00:39 UT. The region has
since rotated over the West limb. NOAA 12232 has newly
rotated on disk. The region was responsible for C-class
activity so far, and shows a beta magnetic configuration.
Further low C-class activity is expected, with the chance
for an isolated high C-class event.
The position of NOAA 12232 on 8-Dec-2014 20:35 UT is:
N10E64 ( -863", 170" )

Dear RHESSI Collaborators,
Solar activity is at a low level. The target region, NOAA
12222 was the source of several more C-class events
since the last message. The target region has further
simplified and has rotated to close to the limb. The
Major Flare Watch is ended at this time. Further low
C-class flares are expected with a chance for an isolated
high C-class flare.
The position of NOAA 12222 on 8-Dec-2014 01:35 UT is:
S19W81 ( 909", -317" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. The target region,
NOAA 12222 was the source of a series of C-class events
and a M1.5 flare on 5-Dec-2014 at 12:25 UT, since the last
message. While the mixed polarity flux joined with the large
leading spot is decaying, its flaring activity continues. The
Major Flare Watch will continue for at least the following 24
hours. Further M-class activity is likely, with a significant
chance for an isolated >M5 flare.
The position of NOAA 12222 on 5-Dec-2014 at 16:35 UT is:
S19W47 ( 674", -321" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. The target region,
NOAA 12222 is the source of an ongoing major event;
a M6.1 flare on 4-Dec-2014 at 18:05. The region was
also the source of C- and M-class events, since the
previous message. The elongated mixed polarity
structure mentioned yesterday has fragmented, and
some of the rapidly moving component spots have
combined with the large positive leading spot, forming
a large mixed polarity structure (with the smaller
negative spots joined at the trailing edge). Given the
significant activity released so far and the ongoing
rapid evolution, a Major Flare Watch is now in effect.
Further M-class events are likely, with a significant
chance for a >M5 flare.
The position of NOAA 12222 on 4-Dec-2014 at 20:35 UT is:
S20W34 ( 513", -339" )

Dear RHESSI Collaborators,
Solar activity is at a moderate to low level. The target region,
NOAA 12222 released the largest event since the previous
message, a C3.8 flare on 3-Dec-2014 at 13:26 UT. The region
has released another series of C-class events. The newly
emerged flux within its intermediate portion appears to be
forming an elongated mixed polarity structure with a strong
PSL and shearing motions. High C-class activity is likely, with
the chance for an isolated M-class event.
The position of NOAA 12222 on 3-Dec-2014 at 20:35 UT is:
S19W22 ( 346", -326" )
