MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Several regions were the source of C-class events in the
past 24 hours. The largest since the last message was a
C3.1 produced by target region NOAA 1652. 1652 has
an E-type/beta-gamma sunspot group with the brightest plage
on the visible disk. A large sunspot (NOAA 1654) has rotated
over the northeast limb at N08 degrees. It is too close to
the limb to ascertain its magnetic configuration. C-class activity
from several regions is likely with a chance of an isolated
M-class event from target region 1652 in the next 24 hour period.
The position of NOAA 1652 on January 08 at 14:00 UT is:
N17E42 (Solar X = -626", Solar Y = 332")

Dear RHESSI Collaborators,
Solar activity has been low over the past 24 hours, with only C1 events
emanating from both NOAA 11652 and NOAA 11653. The target region, NOAA
11652, is now classified as a beta/D-type region and has a propensity to
produce further intermediate level activity as it rotates on to the visible
hemisphere. If possible, also include NOAA 11653 in your field of view.
The position of NOAA 11652 on 7-Jan-2013 at 06:00 UT is:
N20E57, ( -770", 366" )

Dear RHESSI Collaborators,
The target region that produced the M1.7 flare yesterday has now been
designated as NOAA 11652. Both it and NOAA 11653, also on the northeast
limb, have produced a number of low C-class flares over the past 24 hours.
Further C-level activity from NOAA 11652 is likely with chance for another
isolated M-class flare. If possible, also include NOAA 11653 in your field
of view.
The position of NOAA 11652 on 6-Jan-2013 at 10:00 UT is:
N20E68, ( -850", 355" )

Dear RHESSI Collaborators,
Despite its beta-gamma-delta configuration and continued growth, NOAA 11640
has remained quiescent as it approaches the western limb. A new, as yet
unnumbered, active region behind the northeastern limb was the source of an
M1.7 flare at 09:26 UT today and shall be the new target region. The
region's magnetic configuration is unknown at this time but further C-level
activity is likely over the next 24 hours with a chance for another
isolated M-class flare.
The position of the target region on 5-Jan-2013 at 10:00 UT is:
N20E88, ( -916", 335" )

Dear RHESSI Collaborators,
The target region NOAA 11640 is now classified as a beta-gamma-delta region
due to negative flux emergence within the positive trailing spot. The
region continues to increase in size but has only managed to produce a few
C1 flares since the last message. Chance for increased activity over the
next 24 hours if the region continues to develop.
The position of NOAA 11640 on 4-Jan-2013 at 10:00 UT is:
N28W41, ( 566", 497" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels despite the target region NOAA
11640 growing to over 200 uH. The region retains its beta configuration but
has developed into an E-type sunspot group. Additional B-level activity
expected over the next 24 hours.
The position of NOAA 11640 on 3-Jan-2012 at 10:00 UT is:
N28W27, ( 392", 503" )

Dear RHESSI Collaborators,
The target region NOAA 11640 continues to increase in size but remains
quiescent. The region retains its beta classification but has become
increasingly bright in H-alpha emission. Still a good chance for
low-to-intermediate level activity as the region continues to develop.
The position of NOAA 11640 on 2-Jan-2013 at 06:00 UT is:
N28W09, ( 135", 506" )

Dear RHESSI Collaborators,
The target region NOAA 11640 was the source of a C1.2 flare at 08:47 UT
today. The region has doubled in size as it crosses the central meridian
but retains its bipolar configuration. Further B- and C-level activity is
likely.
The position of NOAA 11640 on 1-Jan-2013 at 10:00 UT is:
N28W00, ( 0", 505" )

Dear RHESSI Collaborators,
Solar activity remains at very low levels. NOAA 11639 has steadily decayed
since the last message. The new target region shall be an EFR in the
northeast quadrant, designated NOAA 11640. NOAA 11640 is currently
classified as a beta/D-type active region and may produce some low level
activity if it continues to develop.
The position of NOAA 11640 on 31-Dec-2012 at 10:00 UT is:
N28E14, ( -209", 502" )

Dear RHESSI Collaborators,
NOAA 11635 was the source of a C1.5 flare at 19:27 UT yesterday but is now
rotating behind the western limb. The new target region shall be NOAA
11639, a small beta region in the southeast quadrant. No significant
activity expected over the next 24 hours.
The position of NOAA 11639 on 30-Dec-2012 at 10:00 UT is:
S16E40, ( -604", -233" )
