MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare was at a low level for the past 24 hours. The
largest event was a B8.1 at 09/24/02:09 UT produced by
target region NOAA 1850. New flux is emerging just north
of the old leader sunspot. There is an increased chance
of C-class activity in the next 24 hour period.
The position of NOAA 1850 on Sept. 24 at 11:30 UT is:
N10E20 (Solar X = -324", Solar Y = 058")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is very low. The background x-ray
flux is flat- lined at the B2.0 level. The largest event in
the past 24 hours was a B6.0. Its source region was
target region NOAA 1850. 1850 has a C-type/beta sunspot
group and is slowly decaying. No significant flare activity
is expected anytime soon.
The position of NOAA 1850 on Sept. 23 at 15:30 UT is:
N10E30 (Solar X = -473", Solar Y = 066")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is currently at very low levels. The
background x-ray flux is B2.3. The largest event in the
past 24 hours was a B6.0 at 09/22/02:47 produced by
target region NOAA 1850. 1850 is slowly decaying.
There is still a slight chance of a C-class event in the next
24 hour period.
The position of NOAA 1850 on Sept. 22 at 11:30 UT is:
N10E47 (Solar X = -691", Solar Y = 086")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar activity is low. The background x-ray flux is currently
at the B3.7 level. The largest event in the past 24 hours
was a C3.0 at 09/21/10:45 UT. Its source was target region
NOAA 1850. 1850 is displaying slight decay in the trailing
portion of its D-type/beta sunspot group. B- and C-class
events are possible in the next 24 hour period. There is only
a slight chance of a M-class event.
The position of NOAA 1850 on Sept. 21 at 11:00 UT is:
N09 E60 (Solar X = -819", Solar Y = 090")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The northeastern target region has been numbered
NOAA 1850. 1850 was the source of B-class events
and four C-class events since the last message. The
largest was a C3.8 event at 09/20/11:53 UT. The region
is a large mature plage/E-type sunspot group that appears to have
mixed polarities. Additional C-class events possible with
a very slight chance of an isolated M-class event in the next
24 hours.
The position of NOAA 1850 on Sept. 20 at 11:30 UT is:
N08E75 (Solar X = -915", Solar Y = 102")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a low level. The background
x-ray flux is currently B3.0. The largest event in the past 24
hours was a C1.8 at 09/19/08:17 UT. It's source appeared to
be a new region located near the location of old NOAA 1834.
Target region NOAA 1846 is mostly unchanged and quiescent.
The target will switch from 1846 to the new region on the
northeastern limb. B-class events probable with the chance
of another C-class event in the next 24 hour period.
The approximate position of the target on Sept. 19 at 11:30 UT is:
N10E89 (Solar X = -941", Solar Y = 163")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity was low in the past 24 hours. The
largest event was an isolated C3.9 event produced by
the southeastern target now numbered NOAA 1846.
1846 has a C-type/beta sunspot group with a large round
leader sunspot and a few tiny trailing polarity spots.
B-class events probable with the slight chance of another
C-class event in the next 24 hour period.
The position of NOAA 1846 on September 18 at 10:00 UT is:
S17E75 (Solar X = -883", Solar Y = -307")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is very low. The background x-ray flux
is currently at the B2.2 level. The east limb target region
was the source of minor B-class events. The largest was
a B6.1 at 09/16/22:22 UT. A moderate-sized leader sunspot
is now visible on the southeastern limb. B-class events probable
with a slight chance of an isolated C-class event but no significant
events expected in the next 24 hours.
The position of the target on September 17 at 10:45 UT is:
S17E85 (Solar X = -910", Solar Y = -287")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar minimum conditions prevail. The visible solar disk
is almost spotless. The background x-ray flux is currently
flat lined at the B1.5 level. The target will switch from
region NOAA 1841 (S05E05) to a region located just
beyond the southeastern limb. No significant solar flare
activity is expected any time soon.
The approximate position of the target on Sept. 16 at 13:00UT is:
S14E89 (Solar X = -926", Solar Y = -233")

Dear RHESSI Collaborators,
Solar X-ray flux remains flat at the B1 level with no events of note since
the last message. The target region NOAA 11841 remains unchanged in terms
of both size and complexity. No increase in activity expected over the next
24 hours.
The position of NOAA 11841 on 15-Sep-2013 at 11:35 UT is:
S06E21, ( -341", -210" )
