Dear RHESSI Collaborators,
The target region near the southeast limb has now been designated NOAA
11313 and was the source of several C-class flares since the last
message, including a C9.2 flare at 12:36 UT on 5-Oct-2011. The region
has a simple bipolar configuration and is likely to produce further
C-level activity.
The position of NOAA 11313 on 6-Oct-2011 at 09:30 UT is:
S13E59, ( -806", -269" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 11302, now on the western
limb, was the source of a single C2.3 flare at 00:11 UT today. NOAA
11305 has also remained quiescent. There is a new region encroaching
onto the southeast limb, which has been the source of two low C-class
events, and shall be the new target region. Its magnetic configuration
is uncertain at this time but it has the potential to produce further
C-level activity as it rotates onto the visible hemisphere.
The approximate position of the target region on 5-Oct-2011 at 09:30 UT is:
S14E87, ( -929", -236" )

Dear RHESSI Collaborators,
The Sun has been mostly quiescent over the past 24 hours activity,
with NOAA 11302 being the source of a C7.3 flare today at 08:56 UT.
NOAA 11302 and NOAA 11305 have both been downgraded to beta regions
and NOAA 11305 shall remain the target region as it continues to
undergo new flux emergence. Chance for isolated C-level events.
The position of NOAA 11305 on 4-Oct-2011 at 10:30 UT is:
N11W42, ( 631", 102" )

Dear RHESSI Collaborators,
Solar activity remains moderate with some renewed activity from
decaying active region NOAA 11302, including an M1.3 flare at 17:19 UT
yesterday. NOAA 11305 has undergone some minor flux emergence and
shall continue to be the target region. Further C-level events likely
with chance for an isolated M-class flare.
The position of NOAA 11305 on 3-Oct-2011 at 09:30 UT is:
N12W32, ( 498", 106" )

Dear RHESSI Collaborators,
The target region NOAA 11305 was the source of an M3.9 flare today at
00:37 UT. The region retains its beta-gamma configuration around a
unipolar sunspot, and remains magnetically tied to NOAA 11302 and NOAA
11306. Further C- and low M level events likely.
The position of NOAA 11305 on 2-Oct-2011 at 10:30 UT is:
N12W18, ( 297", 95" )

Dear RHESSI Collaborators,
Solar activity is moderate. The target region NOAA 11305 retains its
beta-gamma configuration and was the source of two M-class flares
since the last message. Further intermediate level activity expected.
The position of NOAA 11305 on 1-Oct-2011 at 11:47 UT is:
N12W06, ( 98", 89" )

Dear RHESSI Collaborators,
NOAA 11302 has decayed significantly over the past 24 hours and has
remained relatively quiescent. NOAA 11305, on the other hand, has
increased in both size and complexity and is now classified as a
beta-gamma region. The region was the source of a C7.7 flare today at
03:37 UT and shall be the new target region. Further C-level activity
possible with chance for an isolated low M-class if the region
continues to develop.
The position of NOAA 11305 on 30-Sep-2011 at 09:30 UT is:
N13E10, ( -162", 106" )

Dear RHESSI Collaborators,
Solar background flux remains steady below the C1 level. The target
region NOAA 11302 maintains its large sunspot area with some mixed
polarity within the leader spot, and was the source of a C9.3 and an
M1.1 flare at 12:26 and 13:24 UT, respectively, on 28-Sep-2011.
Further C-level events possible with chance of an isolated M-class
flare.
The position of NOAA 11302 on 29-Sep-2011 at 09:30 UT is:
N13W09, ( 151", 105" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels. At this time we are ending
the Major Flare Watch campaign. NOAA 11302 retains its large sunspot
area but has lost a lot of its complexity. Only C-class flares have
been produced in the past 24 hours. NOAA 11302 shall continue to be
the target region with further C-level events likely as it crosses the
central meridian.
The position of NOAA 11302 on 28-Sep-2011 at 09:30 UT is:
N13E02, ( -38", 103" )

Dear RHESSI Collaborators,
Solar activity has begun to decrease with NOAA 11302 now downgraded to
a beta-gamma region. The largest event since the last message was an
M2.6 flare at 14:37 UT on 26-Sep-2011. We shall continue the Major
Flare Watch for a further 24 hours as the region still has the
potential to produce another >M5 flare.
The position of NOAA 11302 on 27-Sep-2011 at 09:30 UT is:
N13E17, ( -273", 107" )
