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")

Dear RHESSI Collaborators,
Solar activity is low. The largest event since the last message
was a C1.2 at 02:48 UT on February 6 produced by the target
region NOAA 12494. 12494 has decayed to a D-type/beta-gamma
region but increasing in sunspot area and number of spots. It is
showing flux cancellation in the center of its leading positive spot,
also showing mixed polarities in its intermediate portion. It continues
to interact with the region NOAA 12491 (N02W06) through a filament.
Low level activities are expected in the next 24 hour period.
The position of NOAA 12494 on February 6 at 15:30 UT is:
S12W13 (Solar X = 214", Solar Y = -98")

Dear RHESSI Collaborators,
Solar activity increased slightly in the past 24 hours. The target region,
now designated as NOAA 12494, was the source of numerous C-class
flares with the largest being a C5.1 at 18:15 UT on February 4. 12494
has been classified as a complex D-type/beta-gamma-delta magnetic
configuration. It is showing flux cancellation in its intermediate portion,
and interacting with the adjacent region NOAA 12491 (N02E07) between
high-lying loops. More low-to-mid C-class activities are possible in the
next 24 hours.
The position of NOAA 12494 on February 5 at 15:30 UT is:
S12W00 (Solar X = 0", Solar Y = -97")

Dear RHESSI Collaborators,
Solar activity continues at ~C1 level. A few C-class events were
produced by various active regions. The largest event since the
last message was a C2.4 at 12:16 UT on February 4 from a newly
emerged region (S11E19). This new region developed rapidly in
the previous 24 hours and has produced three low C-class events
today. It will be today's target region. Further C-class activities are
expected in the next 24 hour period.
The approximate position of the target on February 4 at 15:30 UT is:
S11E16 (Solar X = -280", Solar Y = -120")
