Dear RHESSI Collaborators,
NOAA 11476 is now in decay and begun to lose complexity. The region
continues to produce C-level activity, the largest of which was a C7.0
flare at 07:21 UT today. At this time we are ending the Major Flare Watch
campaign. Further C-level activity expected with chance for an isolated low
M-class flare.
The position of NOAA 11476 on 13-May-2012 at 05:00 UT is:
N11W21, ( 335", 224" )

Dear RHESSI Collaborators,
NOAA 11476 remains unchanged in terms of its size and complexity and has
only produced C-level activity over the past 24 hours, the largest being a
C6.1 flare at 17:31 UT yesterday. The region still has the potential to
produce another large M-class flare, particularly in the event of new flux
emergence, and so the Major Flare Watch shall remain in effect for a
further 24 hours.
The position of NOAA 11476 on 12-May-2012 at 07:00 UT is:
N11W09, ( 146", 229" )

Dear RHESSI Collaborators,
NOAA 11476 has produced multiple C-level events over the past 24 hours, as
well as an M1.7 flare at 20:20 UT yesterday. The region has slowed in terms
of growth but retains a sunspot area >1000 uh and a beta-gamma-delta
configuration. The polarity inversion line is aligned in an almost
east-west direction and there are signs of negative flux emergence within
the southern positive polarity region. The chance remains for a flare of
magnitude M5 or greater as the region crosses the central meridian.
The position of NOAA 11476 on 11-May-2012 at 09:00 UT is:
N12E03, ( -45", 247" )

Dear RHESSI Collaborators,
NOAA 11476 has produced three ~M5 flares in the past 24 hours. The region
continues to show signs of flux emergence and remains classified as a
beta-gamma-delta region. The polarity inversion line within the leader spot
has become highly sheared due to the sunspot's rotation. Major Flare Watch
shall remain in effect with further >M5 level activity expected, and the
possibility of an X-class flare.
The position of NOAA 11476 on 10-May-2012 at 09:00 UT is:

Dear RHESSI Collaborators,
The target region NOAA 11476 was the source of an M1.4 flare at 13:02 UT
yesterday. The region now has an area of almost 1000 uh, and is classified
as a beta-gamma-delta region due to emerging positive flux within the
negative leader spot. Bright H-alpha emission is visible near the location
of flux emergence and the leader spot is beginning to show signs of
rotation. At this time we are implementing a Major Flare Watch campaign due
to the increased probability of an M5 flare or larger over the next 24-48
hours.
The position of NOAA 11476 on 9-May-2012 at 10:00 UT is:
N11E29, ( -459", 228" )

Dear RHESSI Collaborators,
NOAA 11471 was the source of an unexpected M1.9 flare at 14:03 UT
yesterday. The target region NOAA 11476 has remained relatively quiescent
since the last message but continues to show signs of flux emergence. The
region retains its beta-gamma/F-type configuration and has the potential to
produce further low-to-intermediate level activity.
The position of NOAA 11476 on 8-May-2012 at 09:00 UT is:
N10E43, ( -638", 206" )

Dear RHESSI Collaborators,
NOAA 11476 produced two more M1 flares, as well as several C-class flares,
since the last message. The region is classified as a beta-gamma/F-type
region with a sunspot area >750uH. Steep magnetic gradients around the
negative leader spot is likely to result in further C-level activity with a
good chance for additional low M-class flares.

Dear RHESSI Collaborators,
The target region on the eastern limb, now designated NOAA 11476, was the
source of three M1 flares since the last message. The region is classified
as having a beta configuration with a large leader spot. Further C-level
activity likely with a good chance for additional low M-class flares as the
region rotates onto the solar disk.

Dear RHESSI Collaborators,
Solar activity has begun to increase due to the appearance of a new active
region on the eastern limb. The region has produced several C-class flares
since the last message, but its magnetic configuration is uncertain at this
time. The as-yet unnumbered region may also have been the source of a large
CME observed over the eastern limb in LASCO images on 3-May-2012. Further
C-level activity likely over the next 24 hours with the possibility of an
M-class flare.
The position of the target region on 5-May-2012 at 08:00 UT is:
N13E87, ( -925", 217" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. The target region, NOAA 11469, has
been reclassified as a beta region and has produced two low C-class flares
since the last message. Chance for further isolated low-level events.
The position of NOAA 11469 on 4-May-2012 at 12:30 UT is:
S26W58, ( 726", -387" )
