Dear RHESSI Collaborators,
The source of yesterday's B-class flares on the southeast limb has now been
identified as NOAA 11769 and 11770, both of which appear to be small and
static. However, a rapidly emerging region in the southwest quadrant, NOAA
11768, has also produced some B-level activity and continues to show signs
of flux emergence and shall be the new target region. The region currently
has a beta/D-type magnetic configuration and may produce some C-level
activity over the next 24 hours.
The position of NOAA 11768 on 14-Jun-2013 at 09:00 UT is:
S11W37, ( 559",-193" )

Dear RHESSI Collaborators,
NOAA 11765 has remained quiescent as it rotates over the western limb. A
new, unnumbered region on the southeast limb was the source of a number of
occulted low B-class flares since the last message and shall be the new
target region. The region's magnetic configuration is uncertain at this
time but more low level events are possible as the region rotates into view.
The position of the target region on 13-Jun-2013 at 09:00 UT is:
S20E89, ( -887", -323" )

Dear RHESSI Collaborators,
Solar activity is at very low levels with the GOES X-ray flux consistently
below the B2 level over the past 24 hours. NOAA 11765 continues to decay as
it approaches the western limb. No significant activity expected at this
time.
The position of NOAA 11765 on 12-Jun-2013 at 05:00 UT is:

Dear RHESSI Collaborators,
Solar activity remains at low levels. The target region NOAA 11765 was the
source of a flurry of B-class flares yesterday including a C1.9 flare at
14:18 UT. It has since remained quiescent and has begun to decay on
approach to the western limb. Chance for isolated low level events over the
next 24 hours.
The position of NOAA 11765 on 11-Jun-2013 at 13:00 UT is:
N09W58, ( 792", 142" )

Dear RHESSI Collaborators,
Solar activity has returned to very low levels. The target region NOAA
11765 has remained quiescent and unchanged, although newly emerged positive
polarity flux in the core of the region may lead to increased activity over
the next 24 hours.
The position of NOAA 11765 on 10-Jun-2013 at 09:00 UT is:
N08W41, ( 615", 126" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1762 was the source of three limb
occulted C-class events since the last message. The
largest was a C3.7 event at 06/09/02:08 UT. 1762 has
rotated too far from the visible disk to continue to be the target.
The new target will be NOAA 1765. 1765 is currently displaying
a simple D-type/beta sunspot group. B-class events probable
with a chance of a C-class event in the next 24 hours.
The position of NOAA 1765 on June 09 at 13:00 UT is:
N08W31 (Solar X = 483", Solar Y = 126")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1762 was the source of a major M5.9 event at
06/07/22:49 UT. 1762 is now located a little beyond the
southwestern limb but it will remain the target for one
more 24 hour period. There is a chance of catching a
limb flare in the next 24 hours. NOAA 1765, N08W18 is
currently the only sun spotted region on the visible solar
disk.
The position of NOAA 1762 on June 08 at 13:00 UT is:
S28W91 (Solar X = 833", Solar Y = -443")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1762 was the most "active" region on the visible solar
disk since the last message. It was the source of three
minor C-class events. The largest was a C3.0 at 06/07/11:51 UT.
1762 continues in decay phase losing its beta-gamma
magnetic configuration. Another C-class event is possible
before 1762 completes west limb passage.
The position of NOAA 1762 on June 07 at 13:00 UT is:
S28W80 (Solar X = 822", Solar Y = -444")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity has returned to a very low level.
NOAA 1762 was the source of only two minor
B-class events since it produced the M1.3 event
yesterday. 1762 is retaining its beta-gamma-delta
magnetic classification but the already weak delta
configuration appears to be decaying. A C-class event
is possible with an isolated M-class event becoming
less likely in the next 24 hours.
The position of NOAA 1762 on June 06 at 13:00 UT is:
S30W67 (Solar X = 754", Solar Y = -473")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1762 was the source of an isolated M1.3 event
at 06/05/08:56 UT. 1762 is maintaining its D-type/beta-gamma-delta
sunspot group. The weak delta configuration is located within the
large penumbra of the trailing sunspot. C-class events are probable.
Another isolated M-class is also possible in the next 24 - 48 hours.
The position of NOAA 1762 on June 05 at 13:00 UT is:
S28W55 (Solar X = 685", Solar Y = -443")
