Dear RHESSI Collaborators,
Solar activity remains at low levels today. NOAA 11602 is showing bright
EUV emission, although it has yet to produce any activity. Therefore, as
the region with most complex magnetic field and the most flare productive
region, NOAA 11598 will remain today's target. Activity above C-class is
not expected today.
The position of NOAA 11598 on 31-Oct-2012 14:00 UT is:
S11W59 ( 814", -221" )

Dear RHESSI Collaborators,
Solar activity is low. NOAA 11598 has decayed to a single-spot beta class
region, although it retains much of its H-alpha emission. A new, possibly
emerging region - 11602 - has been named on the south east limb. However,
this region is still quite small. Therefore, 11598 will remain the target
of opportunity for the next 24 hours. B and C class flaring activity is
possible.
The position of NOAA 11598 on 30-Oct-2012 14:00 UT is:
S11W45 ( 672", -237" )

Dear RHESSI Collaborators,
NOAA 11598 is continuing to decay. The area of the leading spot remains
approximately constant, but the trailing spot has significantly decayed and
has been reclassified to beta class. This region has produced a single
C-class flare in the past 24 hours and activity is not expected to increase
in the immediate future. Meanwhile, NOAA 11596 appears to be growing in
complexity, with its leading spot now classified as beta-gamma. However,
given the proximity of this region to the east limb, 11598 will continue as
the target for the next 24 hours.
The position of NOAA 11598 on 29-Oct-2012 at 14:00 UT is:
S11W31 ( 490", -249" )

Dear RHESSI Collaborators,
Solar activity is at a low level. Target region NOAA 11598 continues in
decay phase, maintaining spot area coverage but decreasing in number of
spots. This region is classified by NOAA as a beta-delta/D-type sunspot
group. 11598 has a strong polarity inversion line where numerous small
negative trailing spots encroach on the leading positive spot penumbra.
C-class activity is possible in the following 24 hours.
The position of NOAA 11598 on 28-Oct-2012 at 17:30 UT is:
S11W20, ( 320", -257" )

Dear RHESSI Collaborators,
NOAA region 11598 continues in decay phase, although only decreasing
slightly in spot area coverage and maintaining number of spots. This
region remains a beta-delta/D-type sunspot group classification from
NOAA, due to the penumbra of one of the small trailing negative spots
now touching the penumbra of the large leading positive spot. 11598
has only produced one C-class event since yesterday's message (a C1.1
flare on 26-Oct-2012 at 15:49 UT). Further C-class activity is likely
in the following 24 hours.
The position of NOAA 11598 on 27-Oct-2012 at 13:00 UT is:
S12W03, ( 53", -280" )

Dear RHESSI Collaborators,
Target region NOAA 11598 has continued to decay over the past 24 hours,
maintaining spot area while fragmenting and increasing number of spots.
This region has a NOAA designation as a beta-delta/D-type sunspot group,
but the delta appears to have disappeared because the opposite polarity
regions have separated (i.e., it might now be a beta-gamma class). NOAA
11598 has only produced B-class activity in the past 24 hours. At this
time we are ending the Major Flare Watch campaign. C-class activity is
possible over the next 24 hours.
The position of NOAA 11598 on 26-Oct-2012 at 09:30 UT is:
S12E13, ( -209", -280" )

Dear RHESSI Collaborators,
Target region NOAA 11598 is beginning to show signs of entering decay
phase, having decreased in number of spots and area coverage over the
previous 24 hours. This region has maintained a NOAA designation as a
beta-delta/D-type sunspot group, also showing a mixed polarity region
in its lower trailing spots. Although 11598 has only produced C-class
activity since the last message, the Major Flare Watch campaign will
remain in effect for another 24 hours due to the continued presence
of an evolving strong field gradient delta spot.
The position of NOAA 11598 on 25-Oct-2012 at 11:00 UT is:
S12E23, ( -369", -276" )

Dear RHESSI Collaborators,
Target region NOAA 11598 has continued to grow in number of spots, spot
area, and magnetic complexity in the past 24 hours. This region has now
been designated by NOAA as a beta-delta/D-type sunspot group class. The
furthest trailing spots of 11598 also appear to have the same magnetic
polarity as the main leading spot. NOAA 11598 has continued to produce
C-class events (eight in total) since the X1.8 flare on 23-Oct-2012 at
03:13 UT. The Major Flare Watch continues as NOAA 11598 has maintained
a strong polarity inversion line in its delta spot region, indicating
the potential for further flaring above the M5 level.
The position of NOAA 11598 on 24-Oct-2012 at 14:00 UT is:
S12E36, ( -560", -268" )

Dear RHESSI Collaborators,
NOAA 11598 has grown in sunspot area and number of spots. Although
designated as a beta magnetic complexity, this region appears to
have developed a delta spot in its lower trailing spot group. NOAA
11598 was the source of 2 major flares since the last message - an
M5.0 flare on 22-Oct-2012 at 18:38 UT and an X1.8 on 23-Oct-2012
at 03:13 UT. The Major Flare Watch campaign will remain in effect,
as 11598 has the potential to produce additional flares >/=M5 in
the following 24 to 48 hours.
The position of NOAA 11598 on 23-Oct-2012 at 12:30 UT is:

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11598 has increased in number of spots, spot
area coverage, and complexity as continues to rotate onto the visible disk.
However, proximity to the limb prevents accurate determination of a
magnetic
configuration. This region has continued to produce several C-class events
in the past 24 hours and an M1.3 flare on 21-Oct-2012 at 19:46 UT. The
Major
Flare Watch campaign will continue over the following 24 hours, as 11598
may
still produce another >/=M5 flare.
The position of NOAA 11598 on 22-Oct-2012 at 12:30 UT is:
S12E63, ( -842", -239" )
