Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 11471 has remained quiescent
and unchanged over the past 24 hours. NOAA 11469, on the other hand, has
undergone some flux emergence and is now classified as a beta-gamma region.
The region produced three ~C2 flares since the last message and shall be
the new target region. Further C-level activity possible, with chance for
an isolated M-class flare if flux emergence continues.
The position of NOAA 11469 on 3-May-2012 at 12:00 UT is:
S23W46, ( 628", -330" )

Dear RHESSI Collaborators,
Solar activity has been low over the past 24 hours. The target region, NOAA
11471, remains unchanged in terms of size and complexity, and produced only
a B5.7 flare at 17:11 UT yesterday. Further B- and C-level activity
possible.
The position of NOAA 11471 on 2-May-2012 at 08:30 UT is:
S21E29, ( -434", -287" )

Dear RHESSI Collaborators,
The target region, NOAA 11471, was the source of a C3.9 flare at 04:35 UT
today. The region retains its beta configuration but has shown signs of new
flux emergence, with mixed polarities in both the leader spot and trailing
plage. Further C-level activity likely with chance for an isolated low
M-class flare.
The position of NOAA 11471 on 1-May-2012 at 14:00 UT is:
S22E37, (-537", -307" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, NOAA 1471, was the source of a few C-class
events since the last message. The largest was a C6.0
at 04/30/10:41 UT. The region's sunspot group is a simple
C-type/beta but there is some minor mixed polarities within
the large plage area. Another C-class event is possible with
only a slight chance of an isolated M-class event in the next
24 hour period.
The position of NOAA 1471 on April 30 at 11:00 UT is:
S23E55 (Solar X = -720", Solar Y = -335")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, now numbered NOAA 1471, has rotated onto
the visible disk. 1471 is still too close to the limb to
ascertain it magnetic configuration but it appears that there
is a tiny opposite polarity spot located within the penumbra
of the large leading polarity umbra. A C-class event possible
with a slight chance of an M-class event.
The position of NOAA 1471 on April 29 at 13:00 UT is:
S23E68 (Solar X = -814", Solar Y = -347")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region continues to decay quietly. We'll switch to
the new region rotating over the southeast limb. The new
target region has bright plage and is displaying minor surging.
It is too close to the limb to ascertain its magnetic configuration.
C-class events possible in the next 24 hour period.
The position of the target region on April 28 at 05:00 UT is:
S23E80 (Solar X = -865", Solar Y = -360")

Dear RHESSI Collaborators,
NOAA 1465, continues to slowly decay but remains
the most interesting region on the visible solar disk.
1465 produced a C2.4 event at 04/27/11:02 UT.
The largest x-ray event of the period was an unexpected
M1.1 event at 04/27/08:24 UT. Its source region was
NOAA 1466 (N12W33). C-class events possible with
a slight chance of an isolated M-class event in the next
24 hours.
The position of NOAA 1465 on April 27 at 11:00 UT is:
S18W45 (Solar X = 642", Solar Y = -244")

Dear RHESSI Collaborators,
NOAA 1465 is slowly and quietly decaying but is still the most
interesting region on the visible solar disk. C-class events
possible with a slight chance of an isolated M-class event in
the next 24 hour period.

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1465 is mostly unchanged maintaining an interesting
"self-contained" sunspot group. Most of the region's umbrae
are within a common penumbra but it is not a complex magnetic
delta configuration because the opposite polarity umbrae are
not within a distance of 1 heliographic degree. C-class events
probable with a chance of an isolated M-class event in the
next 24 hour period.
The position of NOAA 1465 on April 25 at 13:00 UT is:
S19W20 (Solar X = 309", Solar Y = -241")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1465 increased its penumbral area. 1465 is a
"self-contained" region with almost all umbrae within
a single large penumba but the opposite polarities are
too far apart to qualify as a complex magnetic delta
configuration. C-class events expected with a chance
of an isolated M-class event in the next 24 hour period.
The position of NOAA 1465 on April 24 at 11:00 UT is:
S18W07 (Solar X = 110", Solar Y = -219")
