Dear RHESSI Collaborators,
A newly numbered region near the southeast limb, NOAA 11865, was the source
of an M2.8 flare at 01:23 UT today and shall be the new target region. At
this time we are implementing MM#019 DST Flare Campaign in support of the
Service Mode operations being run at the Dunn Solar Telescope throughout
the month of October. The region appears to contain some mixed polarity in
its trailing portion and has exhibited some dynamic behavior since the
flare. There is an increased possibility of the region producing another C5
flare or greater over the next 24-48 hours. If supporting the DST Flare
Campaign, please select NOAA 11865 as your target region and observe
between 14:00-17:00 UT when seeing conditions are optimal at the facility.
The position of NOAA 11865 on 9-Oct-2013 at 20:35 UT is:
S20E61, ( -791", -374" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. NOAA 11856 has continued to decay and
has been quiescent since the last message. The active region in the
southeast quadrant responsible for the current B-level activity has now
been designated NOAA 11861 and shall be the new target region. Further
B-level activity likely with chance for an isolated C-class flare. If
possible, also include the adjacent, unnumbered beta region close the
eastern limb in your field of view.
The position of NOAA 11861 on 8-Oct-2013 at 11:35 UT is:
S13E57, ( -786", -271" )

Dear RHESSI Collaborators,
Solar activity is elevated. There have been a number of B-class events, as
well as two C1 flares from a new region on the eastern limb since the last
message, although its magnetic configuration is unclear at this time. NOAA
11856, was the source of a C6.2 flare at 03:58 UT today but appears to be
in decay. NOAA 11856 shall remain the target region for a further 24 hours
with a chance for additional isolated C-level events.
The position of NOAA 11856 on 7-Oct-2013 at 15:35 UT is:

Dear RHESSI Collaborators,
Solar flare activity is at a low level. Since the previous
message, a C1 flare was released by a decayed plage
region (~S05W10) on 06-Oct-2013 at ~14:00 UT, which
does not appear to be likely to produce further activity.
Subsequently, a B-class flare was released from a
region over the East limb, but its magnetic configuration
cannot be gauged. Although yesterday's target has
decayed and now exhibits an alpha magnetic
classification, in the absence of a more productive region,
the target not change for at least one more day. B-class
activity is possible.
The position of NOAA 11856 on 06-Oct-2013 at 20:00 UT is:
N08E20, ( -325", 33" )

Dear RHESSI Collaborators,
Solar flare activity is at a low level. Since the previous
message, NOAA 11857 was responsible for B-class
activity. Coronal connectivity between NOAA 11857
and the target region (NOAA 11856) is still evident.
Neither region's magnetic and coronal configuration
has changed significantly. If the instrument allows,
both regions should be included within the FOV.
B-class activity is expected with the possibility of an
isolated C-class event.
The position of NOAA 11856 on 05-Oct-2013 at 20:00 UT is:
N08E32, ( -504", 42" )

Dear RHESSI Collaborators,
Solar flare activity is at a low level. Since the previous
message, a C2.5 flare was released on 04-Oct-2013 at
03:32 UT from yesterday's target region (NOAA 11856).
The photospheric and coronal configuration of the target
has not changed appreciably since the flare. Nearby
NOAA 11857 is mildly active in X-rays and appears to
be strongly magnetically connected to the target region,
possibly leading to further destabilisation. Continued
B-class activity is expected with a further C-class event
being likely.
The position of NOAA 11856 on 04-Oct-2013 at 20:00 UT is:

Dear RHESSI Collaborators,
Solar flare activity is at a low level. Since the previous
message, a C1.5 flare was released from behind the
West limb on 2-Oct-2013 at 21:51 UT, followed by C1.5
flare released from a decayed plage region (S19E43)
on 3-Oct-2013 at 00:06 UT, coinciding with a filament
lift-off. Neither of the regions show significant evidence
of potential for further activity. Although yesterday's
target region (NOAA 11855) has the largest spot area of
the ARs on disk it now shows signs of decay and no
evidence of activity. On the other hand, a C2 flare is
currently in progress within NOAA 11856, which may be
destabilised by nearby NOAA 11857. B-class
activity is expected with a chance for a further isolated
low C-class flare.
The position of NOAA 11856 on 3-Oct-2013 at 21:00 UT is:

Dear RHESSI Collaborators,
Solar flare activity is at a very low level. There has been
no significant activity since the previous message.
Yesterday's target (NOAA 11855) has not evolved
significantly. B-class activity is probable, while an isolated,
low C-class event is possible.
The position of NOAA 11855 on 2-Oct-2013 at 16:30 UT is:
S14W08, ( 131", -338" )

Dear RHESSI Collaborators,
Solar flare activity is at a low level. Over the previous 24
hours, yesterday's target (NOAA 11850) was responsible
for B-class activity, but has now rotated over the limb. A
new region, designated as NOAA 11855, is rapidly emerging
near disk-center (as two simultaneous bipolar flux emergence
events). The region shows some evidence for a gamma
magnetic classification and contains multiple strong sunspots
in a semi-quadrupolar arrangement. B-class activity is expected
with a chance for a C-class event.
The position of NOAA 11855 on 1-Oct-2013 at 17:00 UT is:

Dear RHESSI Collaborators,
Solar flare activity is at a low level. A C1.2 flare was
released due to a filament lift-off (~N10W33) that spanned
the region between decayed NOAA 11836 and yesterday's
target region (NOAA 11850) on 29-Sep-2013 at 23:39 UT.
The flaring structure appeared to be magnetically connected
to both NOAA regions. Also, the main polarity separation
line within NOAA 11850 has strengthened somewhat.
B-class activity is possible, with a slight chance for a
further low C-class event.
The position of NOAA 11850 on 30-Sep-2013 at 17:00 UT is:
N10W69, ( 884", 126" )
