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" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels. The newly emerged bipolar
region in the southeast quadrant has undergone further development and
has been accompanied by a second emerging region. They are now
designated NOAA 11381 and 11382, respectively; NOAA 11382 being
slightly larger. Chance for isolated low-level events as the regions
continue to develop.
The position of NOAA 11382 on 19-Dec-2011 at 12:00 UT is:
S18E19, ( -299", -281" )

Dear RHESSI Collaborators,
Solar activity has picked up since the last message. There has been
renewed activity from NOAA 11376, including a C3.2 flare at 22:47 UT
yesterday, due to new sunspot development. However, the new target
region shall be the emerging flux region in the southeast quadrant.
The as yet unnumbered region has produced a few B-class flares
recently including a C1.2 event at 23:37 UT yesterday. Chance for
further low-level activity as the region continues to develop.
The approximate position of target region on 18-Dec-2011 at 12:30 UT is:
S19E31, ( -476", -301" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue with NOAA 11374 now in decay. The C1.2
flare at 04:49 UT today emanated from the NOAA 11376/7 region close to
disk center. NOAA 11374 shall remain the target region for a further
24 hours although no significant activity is expected.
The position of NOAA 11374 on 17-Dec-2011 at 13:00 UT is:
S18W44, ( 644", -288" )

Dear RHESSI Collaborators,
Solar background flux has dropped to low B-level with no notable
events in the past 24 hours. NOAA 11374 remains unchanged and shall
continue to be the target region, although no significant activity is
expected at this time.
The position of NOAA 11374 on 16-Dec-2011 at 11:00 UT is:
S18W31, ( 481", -287" )
