Dear RHESSI Collaborators,
Solar activity remains at a low level. Yesterday's target region has
rotated further onto the visible solar disk and still shows no sign
of sunspots. NOAA region 11909 continues to decay and appears to be
fragmenting (having decreased in area and increased in spot number),
while decreasing in complexity to a beta/D-type sunspot group class.
This region produced two C-class events since yesterday's message,
including the largest flare of the period (a C6.7 flare on 5-Dec-2013
at 17:35 UT). Further C-class activity is likely in the next 24 hours.
The position of NOAA 11909 on 6-Dec-2013 at 15:00 UT is:
S17W42, ( 627", -287" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 11909 remains the largest, most
spotted and most complex active region on the visible disk. This region
is classified by NOAA as a beta-gamma/E-type sunspot group, but has only
produced a C1.1 flare (on 4-Dec-2013 at 22:18 UT) since the last message.
Yesterday's target region (the return of X-class productive NOAA 11893)
has rotated over the South East limb and produced several C-class events,
the largest being a C6.2 flare on 4-Dec-2013 at 20:14 UT. This region
appears to consist of spatially-extended strong magnetic flux, but no
spots are visible at this time. Further C-class activity is expected in
the following 24 hours.
The approximate position of this region on 5-Dec-2013 at 15:30 UT is:
S10E73, ( -917", -171" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11909 continues to be the
largest and most complex region on disk, being classified by NOAA as a
beta-gamma/E-type sunspot group. This region now appears to be in decay
phase, having decreased in spot area and number of spots. The largest
magnitude flare in the past 24 hours was a C6.8 event on 4-Dec-2013 at
00:20 UT, originating from a region located just behind the South East
limb. This is the return of the active region previously designated as
NOAA 11893, which produced an X1.0 flare on 19-Nov-2013 at 10:14 UT as
it was rotating over the South West limb. Further C-class activity is
likely in the next 24 hours.
The approximate position of this region on 4-Dec-2013 at 12:30 UT is:
S10E90, ( -958", -169" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target region NOAA
11909 has been flare-quiet since the last message, despite growing
in number of spots (and marginal area growth). This region remains
the largest, most complex region on disk and is designated by NOAA
as a beta-gamma/D-type sunspot group. A new region is rotating over
the South East limb (due to be numbered as NOAA 11912) and was the
source of C-class activity, the most recent being a C1.3 flare on
1-Dec-2013 at 21:53 UT. Low-level C-class activity is possible in
the next 24 hours.
The approximate position of this region on 2-Dec-2013 at 12:30 UT is:
S22E86, ( -900", -365" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. The target region NOAA 11909 has
produced several B-class flares since the last message, and is now
classified as having a beta-gamma configuration. The region continues to
show slight signs of growth, although increased activity is unlikely.
The position of NOAA 11909 on 1-Dec-2013 at 12:35 UT is:
S18E24, ( -377", -313" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue. The target region NOAA 11909 remains
unchanged since the last message. No significant increase in activity
expected over the next 24 hours.
The position of NOAA 11909 on 30-Nov-2013 at 12:35 UT is:
S18E38, ( -571", -313" )

Dear RHESSI Collaborators,
Solar activity remains at the low C-level with events emanating from
multiple active regions. NOAA 11909 retains its beta/D-type configuration
but may have undergone some growth since the last message. Possibility of
isolated low-level events over the next 24 hours.
The position of NOAA 11909 on 29-Nov-2013 at 14:05 UT is:
S18E51, ( -720", -312" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. The target region near the southeast
limb has now been designated as NOAA 11909 and is classified as having a
beta/D-type magnetic configuration. The region has been quiescent over the
past 24 hours but may yet produce additional isolated low-level events.
The position of NOAA 11909 on 28-Nov-2013 at 14:05 UT is:

Dear RHESSI Collaborators,
Solar activity remains at low levels. The new target region on the eastern
limb remains unnumbered and has only produced a few B-level events since
the last message. The region is still too close to the limb to ascertain
its magnetic configuration but further low-level events are expected with
chance for an isolated C-class flare.
The position of the target region on 27-Nov-2013 at 14:05 UT is:
S15E81, ( -927", -255" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels with NOAA 11904 now over the
western limb. A new unnumbered region on the southeast limb has been the
source of a number of C1 flares since the last message and shall be the new
target region. Its magnetic configuration is uncertain at this time but
additional C-level events are possible as the region rotates on to the disk.
The position of the target region on 26-Nov-2013 at 14:05 UT is:
S16E82, ( -926", -271" )
