Dear RHESSI Collaborators,
NOAA region 11413 remains quite fragmented but continues to evolve.
This region has again increased in area and number of spots, while
also further developing mature primary leading and primary trailing
spots. NOAA 11413 is still classed as a beta/C-type sunspot group.
C-class events are possible in the next 24 hours.
The position of NOAA 11413 on 2-Feb-2012 at 09:30 UT is:
N08W12, ( 206", 235" )

Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA region 11413 appears to
have finished emerging, but continues to merge spots into the primary
leading spot. This region is now classified as a beta/C-type sunspot
group. C-class activity is possible in the next 24 hours.
The position of NOAA 11413 on 1-Feb-2012 at 15:00 UT is:
N08W00, ( 5", 237" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 11413 continues
in emergence, having increased in spot area, number of spots, and
complexity. This region is now classified as a beta/D-type sunspot
group with the merging of several leading spots and development of
more mature penumbrae. C-class activity is possible in the next 24
hours, with an increasing chance if NOAA 11413 undergoes some flux
emergence between the leading and following spots.
The position of NOAA 11413 on 31-Jan-2012 at 13:30 UT is:
N08E15, ( -243", 232" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels. NOAA region 11413 has
recently emerged close to existing NOAA region 11410. NOAA 11413
has undergone relatively rapid emergence and appears to be quite
fragmented with a beta magnetic classification. C-class activity
is possible, especially if NOAA 11413 continues in emergence.
The position of NOAA 11413 on 30-Jan-2012 at 17:30 UT is:
N08E28, ( -459", 223" )

Dear RHESSI Collaborators,
The Major Flare Watch comes to an end with the spots of NOAA region
11402 rotating over the North West limb. The limb-passage location
of 11402 continues as the target region because the overlying loops
of 11402 will remain visible for several hours. C-class activity is
possible, with a chance for a footpoint-occulted M-class event.
The approximate position of this region on 29-Jan-2012 at 17:30 UT is:
N29W90, ( 851", 469" )

Dear RHESSI Collaborators,
The level of solar activity has decreased as NOAA region 11402
continues rotating over the North Western limb. The Major Flare
Watch will remain in effect for one more day as there is still
a chance for another >M5 event before NOAA 11402 completely
disappears behind the limb.
The position of NOAA 11402 on 28-Jan-2012 at 17:30 UT is:
N29W90, ( 851", 470" )

Dear RHESSI Collaborators,
Target region NOAA 11402 on the North Western limb produced an X1.7
flare today beginning at 17:37 UT. At this time we are implementing
a Major Flare Watch campaign. There remains a good chance for a >M5
event before the target region rotates completely over the limb.
The position of NOAA 11402 on 27-Jan-2012 at 20:30 UT is:
N29W83, ( 845", 480" )

Dear RHESSI Collaborators,
NOAA region 11402 continues to be the source of C-class events as
it approaches the North West limb, the largest since yesterday's
message being a C5.5 flare on 27-Jan-2012 at 06:24 UT. This region
is currently classified as a beta/D-type sunspot group, although a
higher magnetic complexity may be masked by foreshortening effects
close to the limb. Further C-class events are expected in the next
24 hours, with a chance for an M-class event before limb passage.
The position of NOAA 11402 on 27-Jan-2012 at 11:00 UT is:
N29W78, ( 833", 488" )

Dear RHESSI Collaborators,
NOAA region 11402 has continued to decay, decreasing in area
and number of spots. This region has increased in complexity,
now classed as a beta-gamma/D-type sunspot group. NOAA 11402
has produced several C-class events since yesterday's message
(the largest being a C7.9 flare on 26-Jan-2012 at 01:40 UT).
Further C-class activity is likely in the next 24 hours, with
a small chance for an M-class event.
The position of NOAA 11402 on 26-Jan-2012 at 13:30 UT is:
N26W67, ( 808", 458" )

Dear RHESSI Collaborators,
The Major Flare Watch campaign has now finished. NOAA regions 11401 and
11402 have continued to decay, both producing 1 C-class event yesterday.
NOAA 11401 remains the more complex of these two regions, maintaining a
beta-gamma/E-type sunspot group classification. Further C-class activity
is expected, with a small chance for an M-class event.
The position of NOAA 11401 on 25-Jan-2012 at 10:30 UT is:
N16W58, ( 794", 316" )
