Dear RHESSI Collaborators,
Solar activity continues at very low levels. The visible solar
disk is almost spotless as the target region NOAA 12621
rotates up to the west limb. 12621 has entered the decay
phase and has been downgraded to a beta/B-type region.
Only minor activities are possible in the next 24 hours.
The position of NOAA 12621 on December 29 at 14:30 UT is:
N10W83 (953", 174")

Dear RHESSI Collaborators,
Solar activity has been extremely low with the GOES soft
X-ray flux flat at ~A8 level. The target region NOAA 12621
has been flare quiet since the last message. 12621 now
has a beta/C-type sunspot group, increasing in sunspot area
and number of spots slightly. B-class activities are likely in
the next 24 hour period.
The position of NOAA 12621 on December 28 at 14:30 UT is:
N10W70 (903", 184")

Dear RHESSI Collaborators,
Solar activity has increased slightly. The target region, designated
as NOAA 12621, was the source of numerous B-class events with
the largest one being a B8.3 at 20:56 UT yesterday. 12621 has a
beta/B-type sunspot group. It is displaying mixed polarities in the
leading portion. Further B-class activities are possible in the following
24 hours.
The position of NOAA 12621 on December 27 at 14:30 UT is:
N11W54 (776", 211")

Dear RHESSI Collaborators,
The visible solar disk remains spotless. Yesterday's target region
NOAA 12620 has been quiescent since the last message. Today
the target will switch to a newly emerged region in the northwest
quadrant. This region is displaying some surges in H-alpha images.
B-class activities are very likely in the next 24 hours.
The approximate position of the target on December 26 at 14:30 UT is:
N10W40 (580", 200")

Dear RHESSI Collaborators,
The visible solar hemisphere is now spotless. Solar X-ray flux remains
constant below the B-level. The looptops of NOAA 12620 are still
visible above the southwestern limb and shall remain the target region
for a further 24 hours. No increase in activity is expected.
The position of NOAA 12620 on 25-Dec-2016 at 14:30 UT is:
S23W86, ( 895", -378" )

Dear RHESSI Collaborators,
Solar X-ray flux remains below the B-level. NOAA 12620 is now on the
western limb and has remained quiescent. It shall remain the target
region for a further 24 hours although no change in activity is
expected before it transits the western limb.
The position of NOAA 12620 on 24-Dec-2016 at 14:30 UT is:
S23W86, ( 895", -378" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue. The target region NOAA 12620 has
continued to decay as it approaches the western limb. The region has
been downgraded to an alpha spot and is unlikely to produce any
further activity before west limb passage.
The position of NOAA 12620 on 22-Dec-2016 at 20:30 UT is:
S23W62, ( 794", -367" )

Dear RHESSI Collaborators,
Solar activity continues at extremely low levels. NOAA 12620 has
remained quiescent since the last message and has begun to show signs
of decay. It shall remain the target region as it approaches the
western limb although no significant increase in activity is expected
at this time.
The position of NOAA 12620 on 22-Dec-2016 at 14:30 UT is:
S23W58, ( 762", -365" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The target region in the
southwest quadrant has now been designated as NOAA 12620 and was the
source of a B2.7 flare at 14:12 UT today. The region retains its beta
classification and its anti-Hale polarity. Chance for an additional
isolated low level event.
The position of NOAA 12620 on 21-Dec-2016 at 20:30 UT is:
S23W49, ( 679", -363" )

Dear RHESSI Collaborators,
Solar activity remains at very low levels. NOAA 12619 has now almost
completely decayed. A new region is rapidly emerging in the southwest
quadrant and shall be the new target region. This region is not yet
numbered but it appears to have an anti-Hale configuration and may
bring increased activity over the next 24 hours.
The approximate position of the target region on 20-Dec-2016 at 16:30 UT is:
S22W32, ( 474", -344" )
