Dear RHESSI Collaborators,
Solar activity has returned to low levels. NOAA 11861 has produced a number
of occulted low C-class flares from behind the western limb since the last
message. The region shall remain the target for a further 24 hours until
west limb passage. Additional isolated low-level events possible.
The position of NOAA 11861 on 19-Oct-2013 at 19:35 UT is:
S07W91, ( 955", -115" )

Dear RHESSI Collaborators,
Solar activity remains elevated. A new region near the eastern limb, NOAA
11875, has produced a number of low C-class flares since the last message.
However, NOAA 11861 was the source of a C8.4 flare at 15:15 UT today. NOAA
11861 retains its beta-gamma configuration and shall remain the target
region for another 24 hours as it approaches the western limb. Further
C-level activity expected. The DST will not be performing flare
observations over the weekend and so we are reverting to Default HESSI
Target OP.
The position of NOAA 11861 on 18-Oct-2013 at 21:05 UT is:
S08W82, ( 944", -146" )

Dear RHESSI Collaborators,
Solar activity continues at intermediate levels due to a resurgence from
NOAA 11861 which is now classified as a beta-gamma region. The region has
produced several C-class flares as well as an M1.2 flare at 15:09 UT today.
NOAA 11865, on the other hand, has continued to decay and remained
quiescent. NOAA 11861 will be the target region for the next 24 hours and
we recommend that the DST Flare Campaign remain in effect as the region
approaches the western limb. Chance for additional intermediate level
activity due to renewed flux emergence in the trailing portion of the
region.
The position of NOAA 11861 on 17-Oct-2013 at 19:35 UT is:
S10W69, ( 886", -200" )

Dear RHESSI Collaborators,
Solar activity continues at intermediate levels with NOAA 11865 producing
sustained C-level activity, as well as two M1 flares, since the last
message. A new region on the northeast limb has also been the source of two
occulted C-class flares. NOAA 11865 has decayed significantly in terms of
sunspot area but retains its beta-gamma-delta configuration and shall
remain the target region for a further 24 hours. Isolated C-level events
possible. Cloud coverage has lifted at the DST and so we are reinstating
the DST Flare Campaign at this time.
The position of NOAA 11865 on 16-Oct-2013 at 19:35 UT is:
S21W32, ( 477", -420" )

Dear RHESSI Collaborators,
The target region NOAA 11865 was the source of several C-class flares since
the last message, as well as an M1.1 flare at 08:00 UT today. The region
has undergone renewed flux emergence and retains its beta-gamma-delta
configuration in addition to a highly sheared magnetic neutral line.
Further C-level activity expected with chance for an isolated M-class flare.
The position of NOAA 11865 on 15-Oct-2013 at 19:35 UT is:
S22W19, ( 291", -445" )

Dear RHESSI Collaborators,
Solar activity remains at intermediate levels. The target region, NOAA
11865, was the source of a C8.0 flare at 12:56 UT today but has decayed
significantly over the past 24 hours. The region retains its
beta-gamma-delta configuration and may produce additional, isolated
intermediate level events.
The position of NOAA 11865 on 14-Oct-2013 at 17:05 UT is:
S22W04, ( 62",-451" )

Dear RHESSI Collaborators,
NOAA 11861 has remained quiescent since the last message and has been
downgraded to a beta-gamma region. NOAA 11865, on the other hand, maintains
its beta-gamma-delta configuration and was the source of an M1.7 flare at
00:12 UT today. The region comprises a highly sheared magnetic neutral line
and has shown signs of positive flux emergence along its leading edge. NOAA
11865 shall be the new target region with low-to-intermediate level events
possible.
The position of NOAA 11865 on 13-Oct-2013 at UT is:
S22E08, ( -124", -451" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels since the last message. NOAA
11861 continues to produce sporadic low C-class flares but has not shown
any recent signs of development. At this time we are ending the DST Flare
Campaign although NOAA 11861 shall remain the target region. Additional
isolated low-level events possible.
The position of NOAA 11861 on 12-Oct-2013 at 19:35 UT is:

Dear RHESSI Collaborators,
Solar activity is at moderate levels. A region currently behind the
northeast limb was the source of a partially-occulted M1.5 flare at 07:01
UT today but its magnetic configuration is unknown. Both NOAA 11865 and
NOAA 11861 have continued to produce C-class flares since the last message.
NOAA 11861 shall remain the DST Flare Campaign target region for a further
24 hours. Additional C-level activity likely.
The position of NOAA 11861 on 11-Oct-2013 at 19:35 UT is:

Dear RHESSI Collaborators,
Both NOAA 11865 and NOAA 11861 have produced a number of C1 flares since
the last message. NOAA 11865 is now classified as a beta-delta region but
has begun to show signs of decay. NOAA 11861, on the other hand, has shown
significant development over the past 24 hours and also sports a delta
configuration with negative polarity flux embedded in the penumbra of the
positive leader spot. NOAA 11861 shall be the target region for tomorrow's
DST Flare Campaign between 14:00-17:00 UT. Chance for additional C-level
activity.
The position of NOAA 11861 on 10-Oct-2013 at 19:35 UT is:
