MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region (NOAA 1596,N11E51) is mostly unchanged
and currently quiescent. It continues to display a
large E-type sunspot group with a beta magnetic configuration.
A new region beyond the southeastern limb was the source of an
occulted C3.6 x-ray event at 10/19/20:52 UT. We'll switch to
the southeast limb today. C-class activity possible with a chance
of an isolated M-class event in the next 24 hour period.
The approximate position of the target on October 20 at 13:00 UT is:
S12E88 (Solar X = -942", Solar Y = -203")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target, now numbered NOAA 1596, is a large E-type/beta
region. It was the source of a lone C-class event since
the last message. Another C-class event is possible with
a slight chance of an isolated M-class event in the next
24 hour period.
The position of NOAA 1596 on October 19 at 13:00 UT is:
N11E65 (Solar X = -858", Solar Y = 144")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The east limb target region is now rotating onto the visible disk.
After producing a series of C-class events yesterday, it has been
quiescent. The background x-ray flux is currently at a steady
B5 level. The region is still too close to the limb to ascertain
its magnetic configuration. C-class activity is possible with a
slight chance of an isolated M-class event in the next 24 hour period.
The approximate position of the target on October 18 at 13:00 UT is:
N07E85 (Solar X = -953", Solar Y = 109")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1589 produced two C-class events in the
past 24 hours. A new region located behind the northeastern
limb was the source of four occulted C-class events today.
The largest was a C7.4 at 10/17/07:57 UT. We'll switch from
1589 to the northeast limb today. Additional C-class events
probable with a chance of an isolated M-class event in the
next 24 hour period.
The approximate position of the target on October 17 at 08:00 UT is:
N05E89 (Solar X = -959", Solar Y = 082")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1589 is mostly unchanged maintaining a D-type/beta-gamma
sunspot group and bright plage. A C-class event is possible with a
slight chance of a minor M-class event in the next 24 hour period.
The position of NOAA 1589 on October 16 at 13:00 UT is:
N14W14 (Solar X = 226" Solar Y = 141")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1589 has decayed losing its delta configuration but
is still displaying mixed polarities and bright plage.
There is a chance of a C-class event and a slight chance
of a minor M-class event in the next 24 hour period.
The position of NOAA 1589 on October 15 at 13:00 UT is:
N13E01 (Solar X = -016, Solar Y = 120")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1589 developed a weak delta configuration and is
now classified E-type/beta-gamma-delta but only managed
to produce one C-class event since the last message.
A region located behind the northeastern limb at N13 was
the source of an occulted C4.8 event at 10/14/02:27 UT.
The target will continue to be 1589 for at least one more
24 hour period with a possible switch to the northeastern
limb region tomorrow. Both regions could produce C-class
events with a chance of an isolated M-class event as well in
the next 24 hours.
The position of NOAA 1589 on October 14 at 02:30 UT is:
N13E14 (Solar X = -227", Solar Y = 122")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1589 has increased its sunspot area and magnetic
complexity somewhat with penumbral growth within its
northern portion. Continued growth might result in a delta
configuration. 1589 is currently classified as a D-type/beta-gamma
region. C-class activity probable with an isolated M-class
event possible in the next 24 hour period.
The position of NOAA 1589 on October 13 at 13:00 UT is:
N13E26 (Solar X = -412", Solar Y = 128")

Dear RHESSI Collaborators,
NOAA 1589 is mostly unchanged maintaining its D-type
sunspot group with weak polarity mixing. It was the source
of a few C-class events in the past 24 hours. The largest
was a C9.0 at 10/12/8:20 UT. C-class activity probable with
an isolated M-class event possible in the next 24 hour period.
The position of NOAA1589 on October 12 at 13:00 UT is:

Dear RHESSI Collaborators,
The southeastern limb region that was the source of the
recent M-class events has now rotated onto the visible disk.
It has a disappointing C-type/beta sunspot group with a few
small sunspots. NOAA 1589 is mostly unchanged maintaining
its D-type group with weak polarity mixing.
C-class events possible with a chance of an isolated M-class event
in the next 24 hour period.
The position of NOAA 1589 on October 11 at 13:00 UT is:
N13E53 (Solar X = -749", Solar Y = 155")
