MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1620 appears to have stabilized its growth. It is currently
classified as an E-type/beta-gamma region. 1620 was the source
of numerous C-class events. The largest was a C5.9 at 11/27/02:15 UT.
The largest event in the past 24 hours was an isolated M1.6
at 11/27/15:57 UT produced by decaying region NOAA 1618 (N08W77).
C-class events probable from both 1620 and 1618 with the chance
of an isolated M-class event in the next 24 hour period.
The position of NOAA 1620 on November 27 at 14:00 UT is:
S13W36 (Solar X = 558", Solar Y = -236")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1618, N08W63, continues to slowly decay
and was quiescent. NOAA 1620 continued in strong growth
phase overnight. 1620 is currently a D-type/beta-gamma region.
It was the source of numerous C-class events in the past 24
hours. We'll switch to NOAA 1620 today. Additional C-class
events expected with a slight chance of an isolated
M-class event in the next 24 hours.
The position of NOAA 1620 at 14:00 UT is:
S13W22 (Solar X = 356", Solar Y = -241")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1618 is slowly decaying and has been quiescent in
the past 24 hours. The region is maintaining a weak
E-type/beta-gamma-delta sunspot group. NOAA 1620
(S12W08) has switched into growth phase and is currently
the brightest plage on the visible disk. C-class events possible
from both1618 and 1620 in the next 24 hour period.
There is also a chance of an isolated M-class event from 1618.
The position of NOAA 1618 on November 25 at 14:00 UT is:
N08W49 (Solar X = 728", Solar Y = 118")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1618 continues in decay phase. It was the source of
several C-class events since the last message. The largest
was a C3.3 at 11/24/13:40 UT. Additional C-class events
probable with only a slight chance of an isolated M-class
event in the next 24 hours.
The position of NOAA 1618 on November 24 at 14:00 UT is:
N08W35 (Solar X = 553", Solar Y = 112")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1618 continues in decay phase. It was the source of only
minor C- and B-class events in the past 24 hours. 1618 is currently
classified as an E-type/beta-gamma region. B- and C-class events
probable with a slight chance of an isolated M-class event in the
next 24 hours.
The position of NOAA 1618 on November 23 at 14:00 UT is:
N08W21 (Solar X = 346", Solar Y = 107")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1618 has decayed especially within its central portion where the
main delta configuration has broken apart. There is a weaker
delta located in the trailing area of the region's E-type/beta-gamma-delta
sunspot group. 1618 only managed to produce minor C-class activity
since the last message. We'll continue the MFW for the next
24 hour period. There is still a chance of an isolated event =/>M5.
The position of NOAA 1618 on November 22 at 14:00 UT is:
N09W07 (Solar X = 117", Solar Y = 120")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1618 has developed rapidly increasing its sunspot
count, sunspot area, and magnetic complexity. 1618 is currently
a large E-type/beta-gamma sunspot group with a magnetic delta
configuration located within its central portion. 1618 was the source
of 3 M-class events since the last message. The largest was an
M3.5 at 11/21/15:30 UT. At this time we are implementing Max
Millennium coordinated observing plan #003 (Region Likely To Produce
A Major Flare). A major flare =/>M5 is possible in the next 24 to 48
hours. There is a slight chance of an X-class event as well if 1618
continues in strong growth phase.
The position of NOAA 1618 on November 21 at 14:00 UT is:
N08E06 (Solar X = -100", Solar Y = 101")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1618 continues in growth phase. The region is a cluster
of E-W aligned regions forming a single extended F-type/beta-gamma
sunspot group. 1618 was the source of C-class activity since the
last message. The largest event in the past 24 hours was
an M1.7 at 11/20/12:38 UT. Its source was a region beyond the
northwestern limb. C-class events expected with the chance of
an isolated M-class event in the next 24 hour period.
The position of NOAA 1618 on November 20 at 14:00 UT is:
N09E16 (Solar X = -266", Solar Y = 118")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1619, N10W05, has stabilized displaying
a D-type/beta sunspot group. It produced one minor C-class
event in the past 24 hours. NOAA 1618, N08E29, has added
a significant number of small spots overnight. NOAA 1618 is
composed of a cluster regions aligned east-west forming a
single E-type/beta-gamma sunspot group. The region is currently
in growth phase with bright plage. 1618 was the source of
a C7.0 event at 11/19/02:28 UT. Additional C-class events expected
with a chance of an isolated M-class event in the next 24 hour period.
The position of NOAA 1618 on November 19 at 14:00 UT is:

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1613, S24W27, has decayed significantly
and was mostly quiescent only producing two C-class events.
The largest was a C2.8 at 11/17/18:08 UT. Recently emerged
NOAA 1619, N10E08, is developing rapidly. It has a strong
arch-type filament system with bright plage. It is currently
classified as a D-type/beta-gamma region. It was the source
of a C4.3 event at 11/18/13:07 UT. We'll switch the target to
NOAA 1619 today. Additional C-class events expected with
even an isolated M-class event possible in the next 24 hour period.
The position of NOAA 1619 on November 18 at UT is:
N10E08 (Solar X = -133", Solar Y = 129")
