MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1271 was the source of B-class activity during the past
24 hour period. A new region located just beyond the east
limb at approximately S18 also produced a B6.3 event at
05:35 UT today. Target region, 1271 should produce additional
minor events before it completes west limb passage. The target
will most likely switch to the the east limb region tomorrow.
The position of NOAA 1271 on August 27 at 15:30 UT is:
N17W78 (Solar X = 888", Solar Y = 252")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1271 produced numerous B-class events and two C-class
events in the past 24 hour period. The largest C-class event was
a C2.3 at 08/26/13:13 UT. 1271 has decayed significantly but
could still produce B-class events with a chance of another
C-class event before west limb passage.
The position of NOAA 1271 on August 26 at 10:30 UT is:
N17W62 (Solar X = 802", Solar Y = 223")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1271 has decayed somewhat in overall sunspot area and count
but still remains a large E-type sunspot group and reclaimed
a beta-gamma magnetic classification. B-class events are probable
with a slight chance of an isolated C-class event. There is only
a very slight, <10%, chance of an M-class event in the next
few days.
The position of NOAA 1271 on August 25 at 15:30 UT is:
N17W51 (Solar X = 707", Solar Y = 205")

Dear RHESSI Collaborators,
Solar flare event activity continues at a low B-class level.
Target region, NOAA 1271, is mostly unchanged currently
displaying a large E-type/beta sunspot group. There is a new
region located mostly beyond the east limb at approximately
N16 that was also the source of a B-class event today.
B-class events are expected with a chance of a C-class event in
the next 24 hour period. There is <10% chance of an
isolated M-class event in the next few days.
The position of NOAA 1271 on August 24 at 15:30 UT is:
N17W38 (Solar X = 560", Solar Y = 188")

Dear RHESSI Collaborators,
Solar activity remains low with one C class flare in the past 24
hours, produced by NOAA 11271. Given that all regions on disk appear
to be decaying and 11271 remains the only region with multiple, large
penumbral sunspots and a beta-gamma classification, it shall continue
to be todays target. C class activity may be possible.
The position of NOAA 11271 on 23-Aug-2011 15:30 UT is:
N17W25 ( 384", 176" )

Dear RHESSI Collaborators,
Solar activity remains at mid-low levels. There have been numerous B
class flares produced by NOAA 11271 and 11272 along with two low C
class flares. There are two new active regions on the east limb - NOAA
11274 and 11275. 11274 appears to be in decay although it is unclear
whether 11275 is emerging or decaying at this point in time. Although
11271 and 11272 are also in their decay phases, 11271 will continue to
be todays target as it is the largest region on disk with the most
number of sunspots. C class activity is possible.
The position of NOAA 11271 on 22-Aug-2011 15:30 UT is:
N16W10 ( 158", 151" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. NOAA 11271 produced the largest
flare of the last 24 hours - a C2.9 - at 23:00 UT. There is a newly
numbered region near the north east limb, NOAA 11274, whose magnetic
topology is difficult to determine due to its proximity to the limb.
As such, today's target will remain NOAA 11271. Although clearly in
decay, this region is now at disk center and is retaining its
penumbral sunspots and some of its magnetic complexity. C-class
activity possible.
The position of NOAA 11271 on 21-Aug-2011 15:30 UT is:
N17E1 ( -10", 167")

Dear RHESSI Collaborators,
Solar activity is low although NOAA 11271 and 11272 have produced
multiple B class flares between them. Both regions appear to be in the
early stages of decay with signs of fragmentation particularly clear
in 11271 which has also lost its delta classification. Despite this,
11271 will continue to be todays target as it retains a beta-gamma
classification and has three large, bipolar sunspots all of which have
strong penumbra. C class activity is possible over the next 24 hours.
The position of NOAA 11271 on 20-Aug-2011 15:30 UT is:
N17E14 ( -217", 171" )

Dear RHESSI Collaborators,
Activity levels have been low over the past 24 hours with only minor B
class flares produced. A new region - NOAA 11273 - has emerged in the
south west quadrant and appears to be reasonably simple and compact at
this time. NOAA 11272 remains largely unchanged and may still be the
source of some mid size flares. NOAA 11271 will continue to be the
target of choice today. It is holding its large, complex structure and
retains its beta-gamma-delta classification.
The position of NOAA 11271 on 19-Aug-2011 15:30 UT is:
N16E29 ( -443", 165" )

Dear RHESSI Collaborators,
Solar activity continues at moderate levels with continued C class
activity from NOAA 11271 and 11272. Although both regions are likely
to flare, NOAA 11271 will continue as today's target. Its
beta-gamma-delta magnetic configuration, bright H-alpha along the
magnetic inversion line and multiple large, penumbral sunspots make it
the best candidate for >=M class activity.
The position of NOAA 11271 on 18-Aug-2011 15:30 UT is:
N16E41 ( -599", 178" )
