MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1455, was the source of numerous B-class
events since the last message. The largest was a B9.8 event
at 04/14/00:47 UT. 1455 is maintaining a D-type/beta-gamma
sunspot group. B-class activity is expected with the chance
of a C-class event in the next 24 hour period.
The position of NOAA 1455 on April 14 at 13:00 UT is:
N07W27 (Solar X = 432", Solar Y = 199")

Dear RHESSI Collaborators,
NOAA region 11455 has continued to emerge new flux in the last 24 hours.
This region has increased in spot area and number of spots, and produced
B-class activity. NOAA 11455 is now classified as a beta/D-type sunspot
group, with the trailing positive polarity spots still developing mature
penumbrae. More B-class activity is expected, with a chance for C-class
activity if 11455 continues to undergo flux emergence.
The position of NOAA 11455 on 13-Apr-2012 at 11:00 UT is:
N06W11, ( 184", 193" )

Dear RHESSI Collaborators,
Yesterday's target is now designated as NOAA region 11455. This region
has merged some smaller spots into more substantial leading spots, with
additional spot emergence. NOAA 11455 was the source of several B-class
events and has a beta/C-type sunspot group classification. More B-class
activity is expected in the next 24 hours, with a chance for a C-class
flare if 11455 continues to emerge new flux.
The position of NOAA 11455 on 12-Apr-2012 at 09:00 UT is:
N07E03, ( -50", 213" )

Dear RHESSI Collaborators,
The level of solar activity remains low. Yesterday's target was the
source of 2 B-class flares and is now designated as NOAA 11454 with
a beta/C-type sunspot group classification. A newly spotted region
appeared in the North East quadrant a few hours before today's NOAA
number designations were issued. This region has experienced bipolar
flux emergence within pre-existing negative plage field, displaying
some polarity mixing between the primary leading and trailing spots.
B-class events are probable in the next 24 hours, with a chance for
C-class activity if this new region continues to emerge new flux.
The approximate position of this region on 11-Apr-2012 at 09:30 UT is:
N08E16, ( -263", 226" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11450 has now rotated
over the North West limb while several currently unnumbered regions
are rotating over the South East limb. The region at ~S25 is likely
to be the return of NOAA region 11440 and that at ~S13 is likely to
be NOAA 11436 returning. The latter region appears to have a spot in
its leading polarity faculae but the region is too close to the limb
to determine a magnetic complexity. B-class activity is possible in
the next 24 hours.
The approximate position of this region on 10-Apr-2012 at 12:00 UT is:
S13E80, ( -919", -198" )

Dear RHESSI Collaborators,
NOAA region 11450 has decreased in number of spots as it nears the
North West limb, most likely due to foreshortening effects, but has
maintained area because of the dominating leading spot. This region
has an alpha/H-type sunspot group classification and produced a C2.6
flare on 9-Apr-2012 at 01:11 UT. Further B-class events are expected,
with a chance of more C-class activity before 11450 rotates over the
North West limb.
The position of NOAA 11450 on 9-Apr-2012 at 09:00 UT is:
N15W80, ( 911", 263" )

Dear RHESSI Collaborators,
Solar activity remains at a very low level. NOAA region 11450 appears
to be decaying as it approaches the North West limb. However, some of
the decrease in spot area, number of spots, and complexity may be due
to foreshortening effects. This region has a beta-gamma/C-type sunspot
group classification. B-class events are possible in the next 24 hours,
with a chance for a C-class event.
The position of NOAA 11450 on 8-Apr-2012 at 09:00 UT is:
N15W64, ( 833", 290" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA region 11450 has increased
in overall spot area as it approaches the North West limb, despite the
continued decay of its trailing and intermediate spots. This region has
maintained a beta-gamma/E-type sunspot group class in the last 24 hours.
More B-class events are probable, with a chance for some C-class events.
The position of NOAA 11450 on 7-Apr-2012 at 10:30 UT is:
N16W51, ( 715", 326" )

Dear RHESSI Collaborators,
NOAA region 11450 has grown in spot area, number of spots, and complexity
in the last 24 hours and is now classified as a beta-gamma/E-type sunspot
group. This region has produced 3 C-class flares since the last message,
the largest being a C3.1 flare on 5-Apr-2012 at 16:16 UT. NOAA 11450 now
appears to be in decay phase, with the trailing spots decreasing in area.
Further C-class events are possible in the next 24 hours.
The position of NOAA 11450 on 6-Apr-2012 at 10:30 UT is:
N15W37, ( 556", 328" )

Dear RHESSI Collaborators,
The level of solar activity remains very low. NOAA region 11450 has
slowed in its evolution, but continues to develop more mature spots
between the leading and trailing spots. This region has maintained
a beta/D-type sunspot group classification and was the source of a
C1.2 flare on 4-Apr-2012 at 16:17 UT. B-class activity is expected,
with a chance for further C-class events in the next 24 hours.
The position of NOAA 11450 on 5-Apr-2012 at 09:30 UT is:
N17W24, ( 377", 371" )
