Dear RHESSI Collaborators,
Solar activity is low. Yesterday's target (12249) has not produced
significant activity since the previous message, and it has now
rotated over the limb. On the other hand, NOAA 12248 was responsible
for a series of low C-class events, which is subsiding. NOAA 12251 has
newly emerged and appears to be forming a mixed polarity spot in its
northern intermediate portion. It has released a low C-class event so
far. Further low C-class activity is expected with a chance for a high
C-class event.
The position of NOAA 12251 on 29-Dec-2014 at 22:35 UT is:
S12E32 (-507",-164")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2249 was the source of C-class events
and an isolated M2.2 event at 12/27/02:16 UT. 2249 is
maintaining its D-type/beta-gamma sunspot group. C-class
events expected with another isolated M-class event possible
in the next 24 hour period.
The position of NOAA 2249 on December 27 at 16:30 UT is:
S12W57 (Solar X = 801", Solar Y = -180")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA regions 2241 and 2242 are now a few days beyond
the southwestern limb. The new target is recently emerged
NOAA 2249. 2249 is currently a developing region with a
D-type/beta-gamma sunspot group. C-class activity expected
with a slight chance of an isolated M-class event in the next
24 hours.
The position of NOAA 2249 on December 26 at 16:30 UT is:
S12W43 (Solar X = 652", Solar Y = -174")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA regions 2241 and 2242 were the source of C-class
limb activity since the last message. 2242 is now approximately
two days beyond the southwestern limb and target region 2241
is on the limb. If possible, include the limb position of 2242
within your F-O-V. Additional C-class events are possible in the
next 24 hours.
The position of NOAA 2241 on December 25 at 16:00 UT is:
S11W90 (Solar X = 958", Solar Y = -186")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2242 is now located just beyond the southwestern
limb. 2242 was the source of a few C-class events since
the last message. The largest was a C4.9 event at 12/23/22:49 UT.
The new target will be NOAA 2241. If possible, include the limb
position of 2242 (S16W91) within your F-O-V. C-class activity is
possible in the next 24 hour period.
The position of NOAA 2241 on December 24 at 12:30 UT is:
S08W68 (Solar X = 896", Solar Y = -122")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2242 continues in decay phase. It was the source
of a few C-class events since the last message. C-class
activity probable with the chance of an isolated M-class
event in the next 24 hour period.
The position of NOAA 2242 on December 23 at 12:30 UT is:
S17W78 (Solar X = 912", Solar Y = -278")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2242 was the source of an M1.0 event at 12/22/01:49 UT
and a few C-class events. 2242 continues in decay phase losing sunspot
area, sunspot count and magnetic complexity.
NOAA 2241 (S10W40) is also decaying and quiescent since the
M1.0 event on 12/21. C-class events expected with the chance
of an isolated M-class event in the next 24 hour period.
The position of NOAA 2242 on December 22 at 12:30 UT is:
S18W64 (Solar X = 834", Solar Y = -288")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2242 was the source of numerous C-class events and
an M1.2 event at 12/21/07:32 UT. NOAA 2241 (S11W31)
was the source of an M1.0 event at 12/21/12:17 UT. Both
2241 and 2242 are currently decaying but are maintaining
somewhat complex beta-gamma-delta magnetic configurations.
We will continue the Major Flare Watch on target region 2242
for the next 24 hours. 2241 and 2242 continue to have
the potential to produce another M-class event.
The position of NOAA 2242 on December 21 at 16:30 UT is:
S19W54 (Solar X = 747", Solar Y = -301")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 2242, was the source of an X1.8/3b
event at 12/20/00:27 UT. 2242 is maintaining its large
complex E-type/beta-gamma-delta sunspot group and bright
dynamic H-alpha plage. NOAA 2241, S09W16, is also an
E-type/beta-gamma-delta region but has been quiescent
since the M6.9 event on 12/18. 2242 has the potential to
produce another major flare in the next 24 to 48 hours.
The position of NOAA 2242 on December 20 at 16:30 UT is:
S18W39 (Solar X = 585", Solar Y = -282")
