MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, now numbered NOAA 1492, has an E-type/beta
sunspot classification. It appears to be a region in decay phase but
it is possible that it will produce a C-class event in the next 24 hour
period.
The position of NOAA 1492 on May 26 at 00:00 UT is:
S13E65 (Solar X = -838", Solar Y = 204")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target EFR, located northwest of NOAA 1486, developed
slowly and is currently a D-type/beta region. The ERF was the
source of a C1.1 event yesterday. We'll switch the target to a
region rotating over the southeast limb that was the source of
several C- and B-class events since the last message.
Additional C-class events possible in the next 24 hours.
The position of the SE limb region on May 25 at 13:00 UT is:
S12E86 (Solar X = -925", Solar Y = -195"

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1484, N11W60, continues in slow decay phase and
was quiet. The target will switch to an EFR. This new region
has several small spots with an interesting E-W magnetic
inversion line and bright H-alpha plage. A C-class event is
possible in the next 24 hour period.
The position of the EFR target on May 24 at 11:00 UT is:
N22W07 (Solar X = 108", Solar Y = 380")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is low. The largest event in the past
24 hour period was a C1.1 at 05/23/00:27. Its source
was target region NOAA 1484. 1484 has decayed
somewhat since the last message. Another minor
C-class event is possible in the next 24 hours.
The position of NOAA 1484 on May 23 at 13:00 UT is:
N10W53 (Solar X = 726", Solar Y = 181")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is very low. NOAA 1484 is mostly unchanged
within its trailing portion but has decayed within its leading portion.
1484 is maintaining weak mixed polarities and is currently
the brightest plage on the visible disk. A C-class event is possible
in the next 24 hour period.
The position of NOAA 1484 on May 22 at 15:00 UT is:
N10W39 (Solar X = 589", Solar Y = 187")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1482, N15W52, is decaying and quiescent.
We'll switch back to NOAA 1484 today. 1484 increased penumbral
area in its following polarity. It has also developed some minor
polarity mixing. A C-class event is possible within the next 24
hours.
The position of NOAA 1484 on May 21 at 15:00 UT is:
N10W26 (Solar X = 410", Solar Y = 192")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1482, is mostly unchanged maintaining
a D-type/beta sunspot classification. Both 1482 and 1484, N10W13,
may produce an isolated C-class event in the next 24 hour period.
The position of NOAA 1482 on May 20 at 17:00 UT is:
N15W40 (Solar X = 590", Solar Y = 270")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, NOAA 1484, is mostly unchanged and was quiet
since the last message. NOAA 1482 is also mostly unchanged
but did produce 2 small C-class events since the last message.
The largest was a C1.1 at 05/19/01:23 UT. We'll switch to
1482 for the next 24 hour period hoping to catch another
C-class event.
The position of NOAA 1482 on May 19 at 15:00 UT is:
N15W26 (Solar X = 402", Solar Y = 276")

Dear RHESSI Collaborators,
Solar activity continues at the C-level. With NOAA 11476 now over the limb,
the new target region shall be NOAA 11484 in the northeast quadrant. The
region is classified as a beta/D-type region and has shown rapid flux
emergence over the past 24 hours. Good chance of low-to-intermediate level
activity if the region continues to develop.
The position of NOAA 11484 on 18-May-2012 at 09:00 UT is:
N09E19, ( -306", 183" )

Dear RHESSI Collaborators,
The target region, NOAA 11476, produced an unexpected M5.1 flare at 01:30
UT today, which resulted in a >100 MeV proton storm. As the region is now
on the western limb further major flaring activity is unlikely. However,
NOAA 11476 shall remain the target region with a chance of producing
additional low-to-intermediate level activity before west limb passage.
The position of NOAA 11476 on 17-May-2012 at 09:00 UT is:
N13W78, ( 905", 221" )
