Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA region 12280 has now
rotated up to the South West limb and has been flare-quiet since
producing the C6.0 event on 12-Feb-2015 at 02:03 UT. NOAA 12282
has shown some signs of decay since yesterday’s message, but has
increased in magnetic complexity to a beta-gamma/E-type sunspot
group classification. This region produced the largest magnitude
flare in the past 24 hours - a B9.6 on 13-Feb-2015 at 02:20 UT.
C-class flares are possible over the next 24 hour period, with
a small chance for an isolated low M-class flare if NOAA 12282
undergoes more magnetic polarity mixing.
The position of NOAA 12282 on 13-Feb-2015 at 16:00 UT is:
N10E07, ( -120”, 280” )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12280 has decayed further in
the past 24 hours as it rotates towards the South West limb, and is
now designated as a beta/D-type sunspot group. This region produced
the largest flare in the past 24 hour period (a C6.0 on 12-Feb-2015
at 02:03 UT). 12282 has simplified slightly in magnetic complexity
(now designated as a beta/E-type sunspot group), but has also grown
marginally in spot area and number of spots. More C-class activity
is expected over the next 24 hours, with a chance for a low M-class
flare.
The position of NOAA 12282 on 12-Feb-2015 at 17:00 UT is:
N11E22, ( -353", 289" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 12280 has decayed
over the past 24 hours as it rotates towards the South West limb,
apparently losing its delta-spot configuration. However, 12282 has
increased in spot area and number of spots and is now designated
as a beta-gamma/D-type sunspot group classification. This region
continued to produce C-class activity over the past 24 hours after
the previous long duration M2.4 event on 9-Feb-2015 at 22:59 UT.
Further C-class flares are expected over the following 24 hours,
with a reasonable chance for another low M-class flare.
The position of NOAA 12282 on 11-Feb-2015 at 22:30 UT is:
N11E36, ( -557”, 275” )

Dear RHESSI Collaborators,
Solar activity is at a low-to-moderate level. NOAA region 12280 has
continued to produce C-class activity in the past 24 hours, as this
region maintained spot area and increased slightly in complexity to
a beta-gamma-delta/E-type sunspot group classification. The largest
flare of the past 24 hours was an M2.4 event on 9-Feb-2015 at 22:59
UT, which was produced by NOAA 12282. However, this region remains
less complex than 12280. Further C-class flares are expected in the
next 24 hours, with a good chance for a low M-class flare.
The position of NOAA 12280 on 10-Feb-2015 at 22:30 UT is:
S07W53, ( 767”, -50” )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12280 remains the largest
and most magnetically complex spotted region on the visible disk.
12280 maintained spot area and increased in number of spots and was
reclassified as a beta-gamma-delta/D-type sunspot region. 12280 has
also continued to produce C-class flares. Further C-class activity
is expected over the next 24 hours, with a chance for an isolated
M-class flare.
The position of NOAA 12280 on 9-Feb-2015 at 23:00 UT is:
S07W38, ( 593", -31" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2280 is maintaining bright H-alpha plage and its
D-type/beta-gamma sunspot group. 2280 was the source
of C-class events in the past 24 hours. C-class events
probable with the chance of an isolated M-class event in the
next 24 hour period. The western portion of the very large
filament located just east of 2280 has become activated.
The position of NOAA 2280 on February 08 at 16:35 UT is:
S08W23 (Solar X = 377", Solar Y = -034")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity was low during the past 24 hours.
NOAA 2280 has developed a new small delta magnetic
configuration within its northern intermediate portion of its
D-type/beta-gamma sunspot group. The small delta that
was located within the southern intermediate area yesterday
has decayed away. C-class events probable with the chance
of an isolated M-class event in the next 24 hour period.
The position of NOAA 2280 on February 07 at 16:35 UT is:
S07W09 (Solar X = 151", Solar Y = -011")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2280 is mostly unchanged and is also mostly quiescent
despite maintaining its small magnetic delta configuration located
within the intermediate portion of its D-type/beta-gamma
sunspot group. C-class events possible with only a slight chance
of an isolated M-class event in the next 24 hours.
The position of NOAA 2280 on February 06 at 16:35 UT is:
S08E05 (Solar X = -084", Solar Y = -028")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar activity is low. NOAA regions 2277 and 2280
produced only C-class activity in the past 24 hours. 2277
developed new flux around its trailing sunspot but decay
was observed within its leading area. 2280 is displaying
a D-type/beta-gamma sunspot group with a delta configuration
that developed in its trailing portion since the last message.
The target will switch to 2280 for at least today. C-class events
expected with the chance of an isolated M-class event
from new target region 2280 and old target region 2277 (N08W28)
in the next 24 hour period.
The position of NOAA 2280 on February 05 at 16:00 UT is:
S08E22 (Solar X = -363", Solar Y =-037")

Dear RHESSI Collaborators,
Target region NOAA 2277 was the source of a few
C-class events and an M1.2/2n event at 02/04/02:15 UT.
C-class events expected with the chance of another
isolated M-class event in the next 24 hour period.
The position of NOAA 2277 on February 04 at 12:30 UT is:
