Dear RHESSI Collaborators,
Solar activity has diminished over the past 24 hours with NOAA 11904 now on
the western limb. The region remains largely unchanged since the last
message but retains its beta-gamma configuration. Chance for isolated
C-level events before west limb passage.
The position of NOAA 11904 on 25-Nov-2013 at 12:35 UT is:
N12W89, ( 950", 201" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1904 was the source of numerous C-class
events. The largest was a C4.7 at 11/24/07:52 UT. 1904 is
mostly unchanged maintaining a D-type/beta-gamma classification.
C-class events probable with a slight chance of an isolated
M-class event in the next 24 hour period.
The position of NOAA 1904 on November 24 at 14:00 UT is:
N12W75 (Solar X = 918", Solar Y = 194")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The southeastern target region has completed east limb passage.
The region has a large plage area with a simple C-type/beta
sunspot group. The most active region on the visible solar disk
is a recently emerged region located north of NOAA 1899.
The region was the source of two M-class events today.
The largest was an M1.1 at 11/23/02:32 UT. The region is currently
displaying a D-type/beta-gamma sunspot group with a cluster of
small spots. C-class events probable with a slight chance of
another isolated M-class event in the next 24 hour period.
The position of the target region on November 23 at 16:00 UT is:
N12W66 (Solar X = 870", Solar Y = 190")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1897 has completed west limb passage. The new
target is a region that produced a limb occulted C3.6 event
at 11/22/14:45 UT. The region is located on the southeastern
limb. Another C-class event is possible in the next 24 hours.
The approximate position of the target on Nov. 22 at 14:45 UT is:
S12E89 (Solar X = -950", Solar Y = -202")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1893 was the source of an isolated M1.2
limb occulted event at 11/21/11:11 UT. 1893 is now located
beyond the west limb. The new target region is NOAA
1897. 1897 is currently displaying a D-type/beta-gamma
sunspot group. 1897 produced a C1.8 event at 11/21/09:08 UT.
The new target position will also catch possible activity from
SW regions 1893,1895, and 1900. C-class event possible
with only a slight chance of an isolated M-class event.
The position of NOAA 1897 on November 21 at 16:30 UT is:
S18W68 (Solar X = 857", Solar Y = -312")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1893 has been quiescent in the past 24 hours.
Its magnetic delta configuration decayed somewhat following
the X1 event yesterday. Another major event =/>M5 is still
possible in the next 24 hour period.
The position of NOAA 1893 on November 20 at 14:00 UT is:
S13W85 Solar X = 942", Solar Y = -221")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region NOAA 1893 was the source of a major X1.0
event at 11/19/10:26 UT. 1893 is maintaining a complex
E-type/beta-gamma-delta sunspot group. At this time we are
implementing Max Millennium coordinated observing plan
#003 (Region Likely To Produce A Major Flare). 1893 has
the potential to produce another event =/>M5 before west
limb passage.
The position of NOAA 1893 on November 19 at 14:00 UT is:
S14W71 (Solar X = 892", Solar Y = -247")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1900 has decayed losing its magnetic
delta configuration but it is maintaining a beta-gamma classification
and was the source of C-class activity. NOAA 1893 located
adjacent (just to the north) of 1900 has increased its sunspot area
and magnetic complexity with a beta-gamma-delta configuration.
If possible include both 1893 and 1900 within the F-O-V. Additional
C-class events expected with the chance of an M-class event
as well.
The position of NOAA 1863/1900 on November 18 at 16:30 UT is:
S16W63 (solar X = 833", solar Y = -286")

Dear RHESSI Collaborators,
The current level of solar activity is low. Yesterday's target
(NOAA 11900) was responsible for multiple C-class events
and a M1.0 flare on 17-Nov-2013 at 05:10 UT. Strong
negative flux has emerged, adjacent to the large following
positive spot in NOAA 11900. This mixed polarity region
may merge to form a large delta spot. Further C-class
activity is expected with a chance for a further M-class
event.
The position of NOAA 11900 on 17-Nov-2013 at 18:00 UT is:
S19W52, ( 723", -341" )

Dear RHESSI Collaborators,
The current level of solar activity is low. Yesterday's
target (NOAA 11897) was only responsible for
C-class activity since the previous message.
Continued flux emergence is evident, but no mixed
polarity spots or strong polarity separation lines are
visible. On the other hand, NOAA 11900 was
responsible for C-class activity and two M-class
flares (a M1.2 flare on 16-Nov-2013 at 04:53 UT and
a M1.6 at 07:49 UT). There is evidence for continued
flux emergence in the region and the large following
positive spot has merged with flux to the North, to
form a mixed polarity spot. Furthermore, adjacent
NOAA 11898 (to the South) also shows flux
emergence, and exhibits at least two small mixed
polarity spots. The target region is designated as
NOAA 11900, but if your FOV allows, it should
include NOAA 11898 (~7 degrees to the South).
Further C-class activity is possible with a chance
for further M-class flares.
The position of NOAA 11900 on 16-Nov-2013 at 17:20 UT is:
S19W38, ( 572", -350" )
