Dear RHESSI Collaborators,
Quiet-Sun conditions continue. NOAA 12259 has continued to decay, and
a newly-emerging region close to disk center has also not resulted in
any increase in activity. The only event of note over the past 24
hours was a C1.0 flare at 05:41 UT from a region behind the northeast
limb. This shall be the new target region. Additional low to
intermediate level events may be possible over the next day or two as
the region rotates into view.
The approximate position of the target region on 18-Jan-2015 at 16:35 UT is:
N07E83, ( -961", 128" )

Dear RHESSI Collaborators,
Solar X-ray flux has dropped to below the C1 level. The target region
NOAA 12259 has remained quiescent over the past 24 hours and continues
to decay. No significant increase in activity is expected at this
time.
The position of NOAA 12259 on 17-Jan-2015 at 12:35 UT is:
S17W43, ( 637", -228" )

Dear RHESSI Collaborators,
Solar activity has returned to background levels with NOAA 12257 now
behind the western limb. The new target region shall be NOAA 12259, a
small beta-delta region in the southwest quadrant. This region has
been in decay over the past few days and is unlikely to produce any
significant activity over the next 24 hours.
The position of NOAA 12259 on 16-Jan-2015 at 12:35 UT is:
S16W31, ( 484", -203" )

Dear RHESSI Collaborators,
Solar activity has begun to decrease with NOAA 12257 now behind the
western limb. The loops of the region remain visible and it may still
produce some minor isolated over-the-limb events over the next 24
hours. As the other active regions on the visible hemisphere have been
less flare-productive, NOAA 12257 shall continue to be the target
region but we are ending the Major Flare Watch at this time.
The position of NOAA 12257 on 15-Jan-2015 at 12:35 UT is:
N07W91, ( 967", 117" )

Dear RHESSI Collaborators,
Solar activity has continued at moderate levels since the last message
with numerous C-class flares and an M2.2 flare emanating from the
target region NOAA 12257. The region is now transiting the western
limb and is likely to remain active. Major Flare Watch shall remain in
effect as the potential still exists for an occulted M-level event
over the next 24 hours.
The position of NOAA 12257 on 14-Jan-2015 at 12:35 UT is:
N07W88, ( 967", 121" )

Dear RHESSI Collaborators,
The target region, NOAA 12257, was the source of an M5.6 flare at
04:13 UT today. The region is still classified as having a
beta-gamma-delta configuration but it is too close to the western limb
to confirm this. At this time we are implementing a Major Flare Watch
campaign due to the increased possibility of another >M5 flare before
west limb passage.
The position of NOAA 12257 on 13-Jan-2015 at 10:04 UT is:
N07W74, ( 931", 138" )

Dear RHESSI Collaborators,
Solar activity remains at intermediate levels with C-class flares
emanating from across the disk. Newly-emerged active region NOAA 12260
has been the source of the largest (~C6) events since the last message
but the target region, NOAA 12257, continues to show signs of flux
emergence in its core. The region is now classified as a
beta-gamma-delta region and is likely to produce further C-level
activity with chance for an isolated M-class flare.
The position of NOAA 12257 on 12-Jan-2015 at 12:35 UT is:
N07W62, ( 856", 152" )

Dear RHESSI Collaborators,
Solar activity is currently at a low level. Yesterday's target (NOAA
12257) was responsible for a series of low to moderate C-class
activity. The mixed-polarity spot within its intermediate portion has
strengthened. Further C-class activity is expected with a chance for a
low M-class event.
The position of NOAA 12257 on 12-Jan-2015 at 01:05 UT is:
N07W56 ( 804", 158" )

Dear RHESSI Collaborators,
Solar activity is currently at a low level. Yesterday's target (NOAA
12257) was responsible for further low C-class activity. The region
shows evidence for a weak mixed-polarity spot in its northern
intermediate portion. Further C-class activity is expected with a
chance for a low M-class event.
The position of NOAA 12257 on 09-Jan-2015 at 20:35 UT is:

Dear RHESSI Collaborators,
Solar activity is currently at a low level. Yesterday's target (now
designated as 12259) was responsible for further low C-class activity.
The region has not evolved significantly and exhibits a simple
magnetic cconfiguration. On the other hand, NOAA 12257 has been
actively emerging and now shows evidence for a gamma configuration.
The region was responsible for the largest event since the previous
message, a C9.6 flare on 09-Jan-2014 at 08:17 UT. Further C-class
activity is expected with a chance for a low M-class event.
The position of NOAA 12257 on 09-Jan-2015 at 20:35 UT is:
