Dear RHESSI Collaborators,
Solar activity is returning to low levels with NOAA 11296 and 11295
now in decay. NOAA 11290 was the source of a C9.3 flare at 11:30 UT on
16-Sep-2011 and shall be the target region for the next 24 hours.
Slight chance of an isolated intermediate level flare before the
region rotates over the southwest limb. If possible also include NOAA
11297 in your field of view.
The position of NOAA 11290 on 17-Sep-2011 at 08:00 UT is:
S13W74, ( 894", -246" )

Dear RHESSI Collaborators,
NOAA 11296, adjacent to NOAA 11295, has increased in sunspot area
producing several low-to-mid C-class flares since the last message,
and shall be the new target region. Further C-level activity expected.
If possible, also include NOAA 11295 and NOAA 11298 in your field of
view.
The position of NOAA 11296 on 16-Sep-2011 at 10:30 UT is:
N27E34, ( -483", 343" )

Dear RHESSI Collaborators,
Five active regions have produced C-level activity since the last
message, the largest event being a C9.2 flare from NOAA 11290 at 20:42
UT on 14-Sep-2011. The region has decayed significantly since. The
target region shall remain NOAA 11295 which has undergone some flux
emergence over the past 24 hours. Further C-level events likely. If
possible also include NOAA 11296 and NOAA 11298 in your field of view.
The position of NOAA 11295 on 15-Sep-2011 at 10:30 UT is:
N20E44, ( -630", 244" )

Dear RHESSI Collaborators,
Solar activity continues at moderate levels. The target region NOAA
11295, which has produced two low C-class flares since the last
message, has been classified as a beta region and may be the decaying
plage of NOAA 11271 from the previous rotation. Further isolated
C-class events possible.
The position of NOAA 11295 on 14-Sep-2011 at 15:30 UT is:
N21E49, ( -677", 267" )

Dear RHESSI Collaborators,
Solar activity remains at moderate levels. NOAA 11283 has now rotated
off the visible disk. The new target region shall be NOAA 11295 which
has produced several C-class flares since rotating on to the eastern
limb, including a C9.9 at 20:30 UT on 12-Sep-2011. Although its
magnetic configuration is unclear at this time, the region is likely
to produce further C-level events with chance for a low M-class flare.
The position of NOAA 11295 on 13-Sep-2011 at 09:30 UT is:
N21E66, ( -817", 295" )

Dear RHESSI Collaborators,
Solar activity remains around the low C-level with NOAA 11283
producing several C-class flares since the last message. NOAA 11289
continues to dominate the visible hemisphere but remains relatively
quiescent. NOAA 11283 shall be the target region for a further 24
hours until it rotates over the western limb. Further C-level activity
expected with slight chance for an isolated M-class flare.
The position of NOAA 11283 on 12-Sep-2011 at 09:30 UT is:
N14W90, ( 925", 228" )

Dear RHESSI Collaborators,
NOAA 11283, now on the western limb, maintains its beta-gamma
configuration and was the source of a C6.6 flare at 08:41 UT today.
NOAA 11289 also continues to show signs of flux emergence and has the
potential to produce moderate level activity. NOAA 11283 shall
continue to be the target region for the next 24 hours and may produce
additional C- or low M-level events before west limb passage.
The position of NOAA 11283 on 11-Sep-2011 at 09:30 UT is:
N13W79, ( 911", 190" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1283 has decayed significantly losing its complex
magnetic delta configuration but it still retains a beta-gamma
classification. 1283 was the source of the M1.1 event at
09/10/07:40 UT. The potential for a major flare has decreased
but another M-class event from 1283 is very possible. NOAA 1289
(N22E28) is slowly developing new flux just southeast of the
large leader sunspot and has produced C-class activity.
If development continues, there will be a chance for an M-class
event.
The position of NOAA 1283 on September 10 at 15:30 UT is:
N17W64 (Solar X = 820", Solar Y = 226")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Solar activity continues at high levels. There have been two M class
flares in the past 24 hours, both of which were produced by NOAA
11283. This region is showing some signs of opposite-polarity flux
emergence both close to the strong leader spot and also in the
trailing plage region. Additionally, NOAA 11289 is showing signs of
activity, producing C class flares. This too is a large, complex,
multispot region that may produce higher level activity. However,
11283 will continue to be the focus of the Major Flare Watch with a
good chance of further >=M activity.
The position of NOAA 11283 on 9-Sep-2011 15:00 UT is:
N16W50 ( 707", 187" )

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Solar activity is high. NOAA 11283 produced a second X class flare -
this time an X1.8 - at 2011/09/07 22:35 UT, again generating a radio
blackout. In addition, it appears that another large flare is
currently underway. At the time of this message the size is high M
class. AR 11283 has not evolved significantly in the past 24 hours and
the rapid sunspot motion observed previously has slowed. However, it
retains its beta-gamma-delta configuration and with the high levels of
activity it is producing, the Major Flare Watch will remain active.
The position of NOAA on 8-Sep-2011 15:30 UT is:
N14W41 ( 608", 140" )
