MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1936, S16W29, is mostly unchanged.
1936 was the source of minor C-class activity since the
last message. There remains a chance that 1936 could
produce an isolated M-class event but a new region located
beyond the southeastern limb was the source of a limb
occulted C8.8 event at 12/31/11:50 UT. There is currently
a large post-flare loop prominence system visible
on the southeast limb. The target will switch to the new east
limb target today. Additional limb activity is possible in
the next 24 - 48 hours.
The approximate position of the target on Dec. 31 at 15:30UT is:
S10E90 (Solar X = -961", Solar Y = -169")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1936 has developed since the last message.
1936 is currently displaying a large E-type/beta-gamma sunspot
group with a weak magnetic delta configuration located within its
intermediate area where there is also a well defined
arch-type-filament system and bright H-alpha plage. 1936 was
the source of several C-type events in the past 24 hours.
The largest was a C5.4 at 12/29/19:30 UT. Additional C-class
events expected with the chance of an isolated M-class event
in the next 24 hour period.
The position of NOAA 1936 on December 30 at 12:30 UT is:
S17W15 (Solar X = 242", Solar Y = -241")

Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. NOAA regions 11934
and 11936 have both emerged new magnetic flux in the past 24 hours.
11934 has been re-designated by NOAA as a beta-gamma-delta/E-type
sunspot group, but has only produced a C2.6 flare since yesterday's
message. 11936 has maintained its beta-gamma/E-type sunspot group
classification but continues to strengthen the mixed polarity spots
in the intermediate portion. This region has produced seven C-class
flares since yesterday's message, and an M3.1 flare on 29-Dec-2013
at 07:49 UT. Further C-class activity is expected over the next 24
hours, with a good chance for another low M-class flare.
The position of NOAA 11936 on 29-Dec-2013 at 19:30 UT is:
S17W05, ( 76", -241" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 11934 and 11936 have both
retained a beta-gamma magnetic classification and shown minor signs
of evolution since yesterday's message. Both regions have continued
to produce C-class activity, with NOAA 11936 being the source of the
largest magnitude flare in the past 24 hours (a C4.4 on 27-Dec-2013
at 12:08 UT). NOAA 11936 will remain the target, as this region has
shown strengthening of its intermediate mixed-polarity spots. More
C-class events are likely over the next 24 hours.
The position of NOAA 11936 on 28-Dec-2013 at 11:30 UT is:
S16E13, ( -207", -228" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA regions 11394 and 11396 are
both classed as beta-gamma magnetic configurations and both produced
low C-class flares since yesterday's message. NOAA 11396 remains the
target, since this region has grown in spot area and number of spots
over the past 24 hour period. Further C-class events are probable in
the following 24 hours.
The position of NOAA 11936 on 27-Dec-2013 at 13:00 UT is:
S16E23, ( -366", -232" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 11928 has now fully
rotated over the South West limb. NOAA 11936 has emerged new magnetic
flux in its trailing spot region over the past 24 hours. 11936 was the
source of 2 low C-class flares since yesterday's message (a C1.7 flare
on 25-Dec-2013 at 16.28 UT and a C1.3 flare on 26-Dec-2013 at 08:09 UT).
Further C-class activity is likely over the next 24 hours, with a small
chance for a low M-class flare if NOAA 11936 continues to emerge new
magnetic flux.
The position of NOAA 11936 on 26-Dec-2013 at 16:30 UT is:
S17E34, ( -523", -254" )

Dear RHESSI Collaborators,
Solar activity has returned to a low level. NOAA 11928 has now rotated
over the South West limb, having previously displayed beta-gamma/D-type
sunspot group characteristics. This region continued to produce C-class
activity, totaling 4 C-class events since yesterday's message (including
the largest magnitude flare, a C4.7 on 25-Dec-2013 at 06:34 UT). Further
C-class events are probable over the following 24 hours, with a small
chance for an isolated low M-class flare before the higher-lying loops
of NOAA 11928 rotate completely beyond the limb.
The position of NOAA 11928 on 25-Dec-2013 at 13:00 UT is:
S16W90, ( 937", -269" )

Dear RHESSI Collaborators,
Solar activity has decreased to a low-to-moderate level. NOAA 11928
has rotated close to the South West limb over the past 24 hours. This
region appears to be decreasing in spot area and number of spots, but
some of this may be due to limb foreshortening effects. 11928 remains
the largest and most complex region on the visible disk (designated a
beta-gamma/E-type sunspot group classification by NOAA) and continues
to produce C-class activity (a total of 4 C-class flares in the past
24 hours, the largest being a C5.3 on 23-Dec-2013 at 15:49 UT). More
C-class flares are expected, with a reasonable chance for an isolated
low M-class flare before NOAA 11928 rotates completely over the limb.
The position of NOAA 11928 on 24-Dec-2013 at 11:00 UT is:
S16W80, ( 924", -263" )

Dear RHESSI Collaborators,
Solar activity is at a moderate-to-high level. NOAA region 11928 has
decreased in spot area and number of spots in the past 24 hours, but
remains the largest and most complex region on disk (designated as a
beta-gamma/E-type sunspot group). 11928 has produced five low M-class
events over the previous 24 hours, the largest being an M3.3 flare on
22-Dec-2013 at 15:06 UT and the most recent being an M1.6 flare on
23-Dec-2013 at 08:59 UT. Further low M-class events are likely, with
a small chance for a flare >= M5 in the next 24 hours.
The position of NOAA 11928 on 23-Dec-2013 at 14:30 UT is:
S17W69, ( 872", -274" )

Dear RHESSI Collaborators,
The current level of solar activity is moderate. NOAA
11934 was responsible for an M1.6 event on
22-Dec-2013 at 14:38 UT. Yesterday's target (NOAA
11928) was released a many C-class events as well
as a M1.9, M1.1, and M3.3 flare on 22-Dec-2013 at
08:11, 08:37, and 15:12 UT, respectively. The region
has increased in sunspot area within its North-Eastern
portion and its central mixed polarity spot has
strengthened. High C-class activity it expected, while
further M-class events are likely.
The position of NOAA 11928 on 22-Dec-2013 at 18:50 UT is:
S17W57, ( 787", -269" )
