MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1654 continues in decay phase as it approaches the west
limb. 1654 produced two C-class events since the last
message. The largest x-ray event yesterday was a
C5.8 at 01/18/17:07 UT. Its source region was a small EFR located
in the trailing polarity of a decayed spotless plage. The EFR has
a few tiny spots. Its current location is N11E17. C-class events
possible with an M-class event unlikely in the next 24 hours.
The position of NOAA 1654 on January 19 at 14:00 UT is:
N07W67 (Solar X = 891", Solar Y = 151")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1654 has decayed losing significant magnetic complexity,
sunspot area and sunspot count in the past 24 hours.
It currently has a simple beta magnetic configuration. NOAA 1652
(N18W90) was the source of minor C-class events during west
limb passage. No significant solar flare activity expected in the
next 24 hours.
The position of NOAA 1654 on January 18 at 14:00 UT is:
N07W55 (Solar X = 794", Solar Y = 166")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1654 is slowly decaying but still has some weak
mixed polarities within the intermediate portion of its
F-type/beta-gamma sunspot group. A C-class event
is possible with a slight chance of an isolated M-class event
in the next 24 hour period.
The position of NOAA 1654 on January 17 at 14:00 UT is:
N06W41 (Solar X = 638", Solar Y = 163")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a low level - no significant flares in
the past several days. NOAA 1654 is mostly unchanged.
It is a large F-type/beta-gamma region with patches of
bright H-alpha plage. The mixed polarity is located within its
intermediate portion. C-class activity probable with the
chance of an isolated M-class event in the next 24 hours.
The position of NOAA 1654 on January 16 at 14:00 UT is:
N06W27 (Solar X = 441", Solar Y = 173")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1654 continues to display a large F-type/beta-gamma
sunspot group and bright H-alpha plage. The intermediate portion
of the region has mixed polarities. Although 1654 has recently only
managed to be the source of C-class events, it is possible that
it could produce an isolated M-class event in the next 24 hour
period.
The position of NOAA 1654 on January 15 at 14:00 UT is:
N08W13 (Solar X = 218", Solar Y = 211")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
No significant changes observed in target region NOAA 1654.
It is maintaining its large F-type/beta-gamma sunspot group.
Both 1654 and NOAA 1652 (N19W36) were the source of C-class
activity in the past 24 hours. Additional C-class events expected
with a chance of an isolated M-class event in the next
24 hour period.
The position of NOAA 1654 on January 14 at 14:00 UT is:
N08W04 (Solar X = 067", Solar Y = 212")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1654 is mostly unchanged maintaining its large
F-type/beta-gamma sunspot group. Despite its large magnetically
complex configuration and dynamic bright H-alpha plage,
1654 has failed to produce a major event =>M5.
The largest events today ( M1.0 at 00:50 and M1.7 at 08:38 UT)
were produced by NOAA 1652, N19W22. 1652 and target 1654
are expected to produce C-class events with the chance of an
M-class event in the next 24 hour period.
The position of NOAA 1654 on January 13 at 14:00 UT is:
N08E10 (Solar X = -168", Solar Y = 209")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1654 has decayed somewhat in the past 24 hours but it
is still maintaining a large F-type/beta-gamma sunspot group with
bright plage. 1654 was only able to produce C-class events
since the M1.0 event on 01/11/15:06 UT. It is less likely but
still possible for 1654 to produce an isolated event =>M5 in the
next 24 hours. The MFW will continue for at least another day.
The position of NOAA 1654 on January 12 at 14:00 UT is:
N08E23 (Solar X = -378", Solar Y = 203")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1654 has increased its magnetic complexity during the past
24 hours. 1654 produced 13 C-class events and two M-class events
since the last message. The M-class events were an M1.2
at 01/11/09:11 UT and a long-duration M1.0 at 01/11/15:06 UT.
1654 is a large F-type/beta-gamma-delta region. The leading
portion of the region has a large amount of opposite polarity plage
surrounding the leader sunspot. At this time we are implementing
Max Millennium coordinated observing plan #003 (Region Likely
To Produce A Major Flare). An isolated M-class event =>M5 is
possible in the next 24 hour period.
The position of NOAA 1654 on January 11 at 14:00 UT is:
N08E39 (Solar X = -609", Solar Y = 191")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1654 produced C-class events in the past
24 hours. It is maintaining its large E-type/beta sunspot group.
Former target NOAA 1652, N19E17, is classified more magnetically complex
with its beta-gamma-delta classification. The small delta configuration
is located in the leading sunspot but 1654 is more dynamic with brighter
H-alpha plage and continuous dark surges. There is a chance of an isolated
M-class event from either region in the next 24 hour period.
The position of NOAA 1654 on January 10 at 14:00 UT is:
N10E52 (Solar X = -758", Solar Y = 211")
