Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA region 11389 appears
to be decaying, with decreased area and increased number of spots.
This region has been reclassified as a beta-gamma/F-type sunspot
group, but once again flare productivity has decreased in the past 24
hours. C-class activity is possible, with a small chance for an isolated
low M-class event.
The position of NOAA 11389 on 3-Jan-2012 at 17:00 UT is:
S22W01, ( 19", -315" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11389 has produced only a
few high B- and low C-class events since the last message. This region
has maintained area, increased slightly in number of spots, and is now
classified as a beta/F-type sunspot group. Continued C-class activity is
expected, with a small chance for an M-class event.
The position of NOAA 11389 on 2-Jan-2012 at 13:00 UT is:
S22E10, ( -157", -318" )

Dear RHESSI Collaborators,
NOAA region 11389 has continued to be flare productive, being the source
of two M-class events since yesterday's message (M2.4 on 31-Dec-2011 at
13:09 UT and M1.5 on 31-Dec-2011 at 16:16 UT). This region has retained
a beta-gamma E-type sunspot group, despite decreasing in both area and
number of spots. Further C-class activity is expected, with a chance for an
additional M-class event in the next 24 hours.
The position of NOAA 11389 on 1-Jan-2012 at 16:00 UT is:
S23E22, ( -343", -338" )

Dear RHESSI Collaborators,
NOAA 11389 continues to increase in size and is now classified as a
beta-gamma region. The region has only produced a couple of low
C-class flares since the last message and has been quiescent since
00:00 UT. Still a chance for some intermediate level activity over the
next 24 hours.
The position of NOAA 11389 on 31-Dec-2011 at 10:00 UT is:
S23E38, ( -554", -346" )

Dear RHESSI Collaborators,
The target region NOAA 11389 has produced three low M-class flares in
the past 24 hours, as well as several C-level events. Both leader
spots contain mixed polarities and the region continues to show signs
of flux emergence. Further C-level activity expected with a good
chance for additional M-class events.
The position of NOAA 11389 on 30-Dec-2011 at 11:00 UT is:
S23E51, ( -703", -355" )

Dear RHESSI Collaborators,
Solar activity is at intermediate levels. The new active region on the
southeast limb, now designated NOAA 11389, has produced several
C-class flares since the last message. The region appears to comprise
two large sunspots with a steep magnetic gradient along the polarity
inversion line. Further C-level activity expected with chance for a
low M-class flare.
The position of NOAA 11389 on 29-Dec-2011 at 09:00 UT is:
S20E64, ( -828", -316" )

Dear RHESSI Collaborators,
Solar activity continues at the C-level. NOAA 11387 retains its
beta-gamma configuration and has produced a couple of low level events
since the last message. However, a new region appearing on the
southeast limb has produced several C-class flares in the past 24
hours including a C6.7 at 21:46 UT yesterday. This shall be the new
target region with further intermediate level activity expected.
The approximate position of the target region on 28-Dec-2011 at 11:30 UT is:
S23E82, ( -889", -375" )

Dear RHESSI Collaborators,
NOAA 11387 continues to develop and is now classified as a beta-gamma
region due to some negative polarity flux encroaching on the positive
leader spot. The region was the source of several C-level events since
the last message, as well as an M2 flare at 20:12 UT yesterday. NOAA
11386 is also now a beta-gamma region and has produced some C-level
events. However NOAA 11387 shall remain the target region with further
C-level activity expected and a chance of another M-class flare.
The position of NOAA 11387 on 27-Dec-2011 at 08:00 UT is:
S22W47, ( 663", -340" )

Dear RHESSI Collaborators,
Solar activity has increased significantly over the last 24 hours due
to a newly emerged region in the southwest quadrant, designated NOAA
11387, which shall be the new target region. It has produced several
C-level events as well as two M-class flares. The region comprises a
circular sunspot group with a complex magnetic configuration. Good
chance for further intermediate level activity.
The position of NOAA 11387 on 26-Dec-2011 at 08:00 UT is:
S22W33, ( 494", -336" )

Dear RHESSI Collaborators,
Solar activity remains low. The two most recent C5 flares came from
NOAA 11376 (at 11:25 UT yesterday, and is now over the limb) and the
spotless region NOAA 11380 (at 08:49 UT today). The target region NOAA
11386 has remained relatively quiet over the past 24 hours. The region
comprises two positive polarity sunspots with surrounding negative
plage and has the potential to produce further C-level events.
The position of NOAA 11386 on 25-Dec-2011 at 10:00 UT is:
S18E58, ( -788", -283" )
