MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity was very low in the past 24 hours. The background
x-ray flux is currenty at the B1.5 level. Target regions NOAA 1623/1625
are slowly decaying. Both regions have declined to simple
D-type/beta sunspot groups. C-class events less likely but still possible
in the next 24 hour period.
The position of NOAA 1623/1625 on December 02 at 14:00 UT is:
N11E15 (Solar X = -248", Solar Y = 176")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1620 was the source of C-class activity in the past
24 hours. The region has completed west limb passage.
The new target will be "stacked" regions 1623 and 1625.
Both regions have D-type/beta-gamma sunspot groups.
C-class events probable in the next 24 hour period.
The position of NOAA 1623/1625 on December 01 at 14:00 UT is:
N12E28 (Solar X = -449", Solar Y = 192")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1620 was the source of C-class activity in the past 24 hours.
The region appears to have lost its delta configuration but remains
a large E-type/beta-gamma region. C-class events probable
with a chance of an isolated M-class event before 1620 completes
west limb passage.
The position of NOAA 1620 on November 30 at 14:00 UT is:
S13W77 (Solar X = 924", Solar Y = -222")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1620 is mostly unchanged maintaining its E-type/beta-gamma-delta
sunspot group classification. 1620 produced several C-class events
and an isolated M2.2 event at 11/28/21:36 UT. Additional C-class
activity expected with a chance of another isolated M-class event
possible in the next 24 hours.
The position of NOAA 1620 on November 29 at 14:00 UT is:
S12W65 (Solar X = 863", Solar Y = -209")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1620 produced C-class activity and an isolated
M1.0 at 11/27/21:26 UT. The region is maintaining an E-type/beta-gamma
sunspot group with a weak delta configuration located within the
intermediate portion of its sunspot group. C-class events probable
with another isolated M-class event possible in the next 24 hour period.
The position of NOAA 1620 on November 28 at 14:00 UT is:
S12W51 (Solar X = 741", Solar Y = -214")

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")

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")

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:

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:
