Dear RHESSI Collaborators,
Solar activity continues at low levels with C-class flares emanating from
active regions NOAA 11476, 11482, and 11484 over the past 24 hours. NOAA
11476 continues to decay and decrease in complexity as it approached the
western limb, and it shall remain the target region with additional
isolated C-level events expected.
The position of NOAA 11476 on 16-May-2012 at 11:00 UT is:
N10W62, ( 828", 184" )

Dear RHESSI Collaborators,
Solar activity remains at the low C-level. NOAA 11476 continues to decay
and has now been reclassified as a beta-gamma region. Further isolated
low-level events expected over the next 24 hours.
The position of NOAA 11476 on 15-May-2012 at 09:00 UT is:
N09W51, ( 735", 175" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels. The target region, NOAA 11476,
continues to decay but remains classified as a beta-gamma-delta region. The
region has produced only low C-class events since the last message,
including a C4.1 flare at 07:14 UT today. Further intermediate level events
expected over the next 24 hours.
The position of NOAA 11476 on 14-May-2012 at 09:00 UT is:
N09W38, ( 582", 184" )

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:
N10E17, ( -271", 215" )

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.
