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" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 11384 has shown further
signs of development over the past 24 hours but has remained
quiescent. The recent C5.2 flare at 08:27 UT today came from NOAA
11386 which has just rotated onto the southeast limb, and shall be the
new target region. Further low-level events possible.
The position of NOAA 11386 on 24-Dec-2011 at 11:00 UT is:
S18E69, ( -865", -290" )

Dear RHESSI Collaborators,
Solar activity is at low levels. NOAA 11382/1 has been relatively
quiet since the last message and has begun to show signs of decay.
Meanwhile, NOAA 11384 in the northeast quadrant continues to grow and
has produced three C-class flares in the past 24 hours. NOAA 11384
shall be the new target region with a chance of further low C-level
events.
The position of NOAA 11384 on 23-Dec-2011 at 12:00 UT is:
N12E30, ( -477", 231" )

Dear RHESSI Collaborators,
NOAA 11384 in the northeast quadrant has increased in size but has
remained relatively quiet. The target region NOAA 11382/1 was the
source of a C5.4 flare at 01:56 UT today, and also continues to
develop. Chance for additional isolated C-level events over the next
24 hours.
The position of NOAA 11382 on 22-Dec-2011 at 11:00 UT is:
S14W17, ( 272", -208" )

Dear RHESSI Collaborators,
Solar activity has increased over the past 24 hours with C-level
events from NOAA 11376, NOAA 11382/1, and a newly numbered region on
the northeast limb NOAA 11384. The target region shall continue to be
NOAA 11382 which is still showing signs of growth and polarity mixing
with NOAA 11381. Further C-class flares likely.
The position of NOAA 11382 on 21-Dec-2011 at 11:00 UT is:
S19W00, ( 8", -292" )

Dear RHESSI Collaborators,
Solar activity continues at low levels with NOAA 11376 producing
several B-class events since the last message. The target region
complex, NOAA 11381/2, has continued to develop with the two beta
regions seeming to merge together. The region was the source of a C1.5
flare at 00:38 UT today and may produce further isolated low-level
events.
The position of NOAA 11382 on 20-Dec-2011 at 10:30 UT is:
S16E07, ( -108", -245" )
