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" )

Dear RHESSI Collaborators,
NOAA 11302 retains its beta-gamma-delta configuration and has produced
3 M-class flares since the last message. The Major Flare Watch will
continue with NOAA 11302 as the target region. Good chance for further
M-level activity with the possibility of an isolated X-class flare.
The position of NOAA 11302 on 26-Sep-2011 at 09:30 UT is:
N12E30, ( -469", 100" )

Dear RHESSI Collaborators,
The Major Flare Watch will continue with target region NOAA 11302. This
region was the source of an X1.9 event on 24-Sep-2011 at 09:21 UT and
has produced 7 M-class events since. NOAA 11302 has increased in area
and spots, and is now classified as an F-type/beta-gamma-delta sunspot
group. Further M-class activity is probable, with a chance for an X-class
event.
The position of NOAA 11302 on 25-Sep-2011 at 13:00 UT is:
N12E40, ( -601", 111" )

Dear RHESSI Collaborators,
Solar activity remains high, with both large E-type/beta-gamma classified
sunspot groups (NOAA 11295 and 11302) producing M-class events in the
last 24 hours. The MFW target will continue to be NOAA 11302 as it rotates
further onto the solar disk, with a chance for a >M5 event if NOAA 11302
undergoes growth or flux emergence.
The position of NOAA 11302 on 24-Sep-2011 at 10:00 UT is:
N13E53, ( -751", 146" )

Dear RHESSI Collaborators,
The target region, now designated NOAA 11302, has been classified as a
beta-gamma region and has a prominent leader spot. The region has
continued to produce high C-level events since the X-class flare
yesterday. Chance remains for an additional major flare within the
next 24 hours.
The position of NOAA 11302 on 23-Sep-2011 at 09:30 UT is:
N11E68, ( -871", 138" )

Dear RHESSI Collaborators,
The target region on the eastern limb produced an X1.4 flare beginning
at 10:29 UT today. At this time we are implementing a Major Flare
Watch campaign. Good chance for an additional >M5 flare within the
next 24 hours.
The position of target region on 22-Sep-2011 at 11:30 at UT is:
N10E88, ( -941", 162" )

Dear RHESSI Collaborators,
The unnumbered active region encroaching over the eastern limb was the
source of an M1.8 flare at 12:04 UT on 21-Sep-2011, as well as several
C-class flares, and shall be the new target region. The magnetic
configuration is uncertain at this time but additional C-class flares
are likely, with increased chance of another M-level event.
The approximate position of the target region on 22-Sep-2011 at 09:30 UT is:
N15E88, ( -922", 241" )

Dear RHESSI Collaborators,
Solar activity remains at intermediate levels with low C-level events
emanating from several active regions. NOAA 11301 shall remain the
target region, which appears to be undergoing sympathetic flaring with
a new active region approaching the eastern limb. If possible, also
include this new region within your field of view. Further C-level
events likely.
The position of NOAA 11301 on 21-Sep-2011 at 10:30 UT is:
N19E45, ( -646", 231" )

Dear RHESSI Collaborators,
Solar activity remains sporadic. NOAA 11296 has continued to decay and
is now classified as an alpha region. At this time the target region
shall revert back to NOAA 11301 which has undergone new flux emergence
and has produced two C6 flares since the last message. Further C-level
activity expected.
The position of NOAA 11301 on 20-Sep-2011 at 09:30 UT is:
N20E57, ( -754", 264" )
