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")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
The largest x-ray event in the past 24 hours was an isolated
M6.9 at 12/18/21:58 UT produced by NOAA 2241 (S09W06).
Target region, NOAA 2242 was the source of several
C-class events and an M1.3 event at 12/19/09:44 UT.
Both regions remain large and magnetically complex with
E-type/beta-gamma-delta sunspot groups and 2242 has bright
dynamic H-alpha plage. Both regions have the potential to
produce a major flare. We will continue to stay with target
region 2242 for at least the next 24 hour period.
The position of NOAA 2242 on December 19 at 16:30 UT is:
S18W26 (Solar X = 408", Solar Y = -280")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2242 is maintaining its E-type/beta-gamma-delta
magnetic configuration with a complex E-W inversion line.
2242 has only managed to produce C-class activity since
the major M8.7 event on the 17th. NOAA region 2241, S10E12,
is also a complex E-type/beta-gamma-delta region with an
E-W magnetic inversion line. Both regions have the potential
to produce a major flare in the next 24 to 48 hours but 2242 will
continue to be the target region.
The position of NOAA 2242 on December 18 at 12:30 UT is:
S18E12 (Solar X = 129", Solar Y = -281")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 2242, produced an M8.7 event
at 12/17/04:50 UT. 2242 has significantly increased its
sunspot count and area since the last message and
continues to maintain its complex E-W magnetic inversion
line. At this time we are implementing Max Millennium
observing plan #003 (Region Likely To Produce A Major Flare).
Another major flare =/>M5 is likely in the next 24 to 48 hours.
The position of NOAA 2242 on December 17 at 12:30 UT is:
S19E04 (Solar X = -064", Solar Y = -299")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2242 was again the source of several C-class events
in the past 24 hours. 2242 is maintaining its magnetically complex
D-type/beta-gamma configuration with an E-W inversion line.
Additional 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 16 at 12:30 UT is:
S19E17 (Solar X = -270", Solar Y = -302")
