Dear RHESSI Collaborators,
The level of solar activity remains moderate. NOAA region 11875 has
grown in area and decreased in number of spots, while maintaining a
beta-gamma-delta/E-type sunspot group class. Of the multiple delta
spots present within NOAA 11875, the delta in the intermediate spot
region strengthened the most (a result of the merging and maturing
of previously existing spots). This region was the source of seven
C-class flares since the last message, as well as an M4.2 flare on
22-Oct-2013 at 21:15 UT. Further C-class activity is expected in the
next 24 hours, with a good chance for additional low M-class events
and a minor chance of a >=M5.0 event if 11875 undergoes new magnetic
flux emergence.
The position of NOAA 11875 on 23-Oct-2013 at 20:00 UT is:
N07W07, ( 119", 32" )

Dear RHESSI Collaborators,
Solar activity is now at a moderate level. NOAA region 11875 has grown
in spot area and number of spots in the past 24 hours, while it is now
classified by NOAA as a beta-gamma-delta/E-type sunspot group. Since
yesterday's message, this region has produced 12 C-class flares and 2
M1.0 flares (on 22-Oct-2013 at 00:14 UT and 14:49 UT). NOAA 11875 now
has several small delta spots located in its trailing and intermediate
portions. C-class events are expected in the following 24 hours, with
a good chance for further low M-class events and a small chance for a
>=M5.0 event. N.B. Despite fulfilling the necessary criteria, we are
*not* initiating a MM#019 DST Flare Campaign at this time due to other
DST targeting commitments.
The position of NOAA 11875 on 22-Oct-2013 at 18:30 UT is:

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11875 maintained spot
area and a beta-gamma/E-type sunspot group classification from NOAA
over the previous 24 hours, while it increased significantly in spot
number. This region has continued to produce low C-class flares since
yesterday's message, with current magnetic observations indicating it
is a beta-gamma-delta region. Further C-class activity is expected in
the next 24 hours, with a chance for an isolated low M-class event if
the delta spot continues to grow in NOAA 11875.
The position of NOAA 11875 on 21-Oct-2013 at 21:30 UT is:

Dear RHESSI Collaborators,
Solar activity remains at low levels with NOAA 11861 now behind the western
limb. The new target region shall be NOAA 11875 which has produced isolated
C-class flares over the past few days. It has has beta-gamma configuration
with signs of flux emergence in its trailing portion. Possibility of
isolated low-level events over the next 24 hours.
The position of NOAA 11875 on 20-Oct-2013 at 21:05 UT is:

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:

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.

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.

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.
