Dear RHESSI Collaborators,
NOAA 12497 is now nearing the western limb and has continued to
produce low-to-mid C-class flares since the last message. The region
appears to be starting to decay but has retained its delta
configuration. NOAA 12497 shall remain the target region for a further
24 hours with more C-level activity expected. Slight chance of another
low M-class flare before west limb passage.
The position of NOAA 12497 on 16-Feb-2016 at 18:35 UT is:
N12W73, ( 909", 233" )

Dear RHESSI Collaborators,
NOAA 12497 has produced numerous C-class flares over the past 24 hours
along with an M1.1 flare at 10:41 UT today. The region continues to
exhibit complex and dynamic behavior as it approaches the western
limb, and remains classified as a beta-gamma-delta/E-type region.
Sustained C-level activity is likely, with chance for an additional
isolated low M-class flare.
The position of NOAA 12497 on 15-Feb-2016 at 21:35 UT is:
N12W61, ( 832", 255" )

Dear RHESSI Collaborators,
Solar activity has remained at the C-level since the last message,
with the largest event being a C6.9 flare at 09:52 UT today. The
target region NOAA 12497 retains its beta-gamma-delta configuration,
with further flux emergence and shearing within the dominant leader
spot. Sustained C-level activity expected over the next 24 hours with
chance for a low M-class flare.
The position of NOAA 12497 on 14-Feb-2016 at 18:31 UT is:
N12W46, ( 685", 279" )

Dear RHESSI Collaborators,
Solar activity is at intermediate levels. The target region NOAA 12497
has produced numerous C-class flares over the past 24 hours as well as
an M1.8 flare at 15:16 UT today. The region continues to show signs of
flux emergence along its leading edge and retains its beta-gamma-delta
configuration. Further C- and low M-class flares possible.
The position of NOAA 12497 on 13-Feb-2016 at 21:35 UT is:
N13W32, ( 503", 312" )

Dear RHESSI Collaborators,
Solar activity has increased substantially since the last message with
NOAA 12497 producing a C8.9 flare at 00:49 UT and an M1.0 flare at
10:36 UT today. The region has decayed in its trailing portion, but
newly emerged positive flux along the leading edge of the negative
leader spot has changed its classification to a beta-gamma-delta
region. Further C-level activity likely over the next 24 hours with
chance for an isolated low M-class flare.
The position of NOAA 12497 on 12-Feb-2016 at 15:31 UT is:
N13W15, ( 246", 324" )

Dear RHESSI Collaborators,
The target region NOAA 12497 was the source of a C2.6 flare at 16:22
UT today. The region continues to show signs of flux emergence and
dynamic activity in its leader spot as it crosses the central
meridian, and it retains its beta-gamma configuration. Further B- and
C-level events possible.
The position of NOAA 12497 on 11-Feb-2016 at 15:35 UT is:

Dear RHESSI Collaborators,
Solar activity levels remain unchanged. The target region NOAA 12497
produced several B-class flares since the last message as well as a
C1.3 flare at 15:12 UT today. The region continues to show signs of
development and is now classified as a beta-gamma region. Additional
low-level events possible over the next 24 hours.
The position of NOAA 12497 on 10-Feb-2016 at 18:35 UT is:
N13E11, ( -181", 325" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. NOAA 12492 has produced a number
of B-class flares since the last message, while the target region NOOA
12497 has remained quiescent. The target region shows some signs of
additional flux emergence but retains its beta/D-type configuration.
There may be some isolated low-level events over the next 24 hours.
The position of NOAA 12497 on 9-Feb-2016 at 13:30 UT is:
N13E28, ( -446", 313" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the
last message was a C1.6 flare from spotless NOAA 12492 at 05:22 UT.
The target region NOAA 12497 continues to show sign of flux emergence
and development but retains its beta configuration. Chance for further
isolated low-level events over the next 24 hours.
The position of NOAA 12497 on 8-Feb-2016 at 15:30 UT is:

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since
the last message was a C2.7 at 11:54 UT on February 7 from
the northern part of active region NOAA 12496. Yesterday's
target NOAA 12494 produced a few high B-class as well as low
C-class events in the past 24 hours. 12494 continues to decay
with losing some of its magnetic complexity. NOAA 12497 and
12496 have shown some developments when further rotating
onto the disk. In particular, 12496 has produced several C-lass
flares (including the largest one) today. These two regions are
displaying flux emergence in their various portions. If possible,
please include both regions within your field of view. Additional
C-class activities are expected in the next few days.
The position of NOAA 12497 on February 7 at 19:30 UT is:
N13E46 (Solar X = -683", Solar Y = 291")
