Dear RHESSI Collaborators,
Solar activity is at a very low level. With NOAA region 11169 rotating over
the NW limb, NOAA 11173 becomes the target of choice. This region has
a beta magnetic configuration and has shown minor growth in area and
number of spots in the past 24 hours. B-class activity is expected.
The position of NOAA 11173 on 18-Mar-2011 at 14:30 UT is:
S29E18, ( -266", -366" )

Dear RHESSI Collaborators,
The level of solar activity is now low. NOAA region 11169 has maintained
a beta-gamma magnetic configuration as it approaches the NW limb. This
region has continued to produce C-class flares, the largest of which was
a long-duration C3.7 event at 17:52 UT on 16-Mar-2011. Further C-class
activity is possible.
The position of NOAA 11169 on 17-Mar-2011 at 16:00 UT is:
N17W84, ( 917", 292" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. NOAA region 11166 has now rotated up
to the NW limb, with an observed decrease in the number of flares. NOAA
regions 11166 and 11169 both display beta-gamma magnetic configurations,
with 11169 being the source of an M1.0 event at 00:18 UT on 15-Mar-2011.
C-class activity is expected, with a small chance of another low M-class event.
The position of NOAA 11169 on 16-Mar-2011 at 15:30 UT is:
N17W68, ( 859", 322" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1169, was the source of C-class activity
and two M-class events since the last message. The largest
M-class event was an M4.2 at 03/14/19:52 UT. The region
has decayed somewhat after the M-class events but is
maintaining a beta-gamma magnetic configuration with
opposite polarity flux still located along the southwestern
edge of the leading polarity penumbra. C-class activity
expected with the chance of another M-class event.
The position of NOAA 1169 on March 15 at 11:30 UT is:
N18W54 (Solar X = 743", Solar Y = 363")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1166 continues in decay phase. NOAA 1169 has
added a small area of opposite polarity flux near the
large leading penumbra. The default target will switch
from 1166 to 1169 today. C-class activity probable with
a slight chance of an isolated M-class event.
The position of NOAA 1169 on March 14 at 11:30 UT is:
N20W41 (Solar X = 596", Solar Y = 414")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1166 has continued in decay phase losing its complicated
beta-gamma-delta magnetic classification. It has decayed to
a simple beta magnetic configuration. NOAA 1169 increased
its sunspot area but is also a beta configuration. 1166 produced
a few C-class events since the last message. Both 1166 and
1169 should produce C-class events with a slight chance of
an isolated M-class event in the next few days.
The position of NOAA 1166 on March 13 at 16:30 UT is:
N09W62 (Solar X = 843", Solar Y = 206")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 1166 has continued to slowly decay but remains a
beta-gamma-delta magnetic class. It produced numerous
C-class events again plus an M1.3 event at 03/12/04:43 UT.
1166 will continue to produce C-class activity with a
good chance of another M-class event in the next
24 hours.
The position of NOAA 1166 on March 12 at 16:30 UT is:
N09W49 (Solar X = 721", Solar Y = 228")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
We will continue the Major Flare Watch on NOAA 1166 for at least
another 24 hours. 1166 has decayed somewhat but is maintaining a
beta-gamma-delta magnetic classification and bright H-alpha plage.
1166 produced several C-class events and an M1.1 event
at 03/10/22:41 UT. NOAA 1169 (N20W03) appears to be forming
a small magnetic delta configuration in its leading portion.
1166 and 1169 are expected to produce C-class events with the
chance of an M-class event as well. An isolated M-class =>M5
is also possible in the next 24 hours.
The position of NOAA 1166 on March 11 at 11:30 UT is:
N09W33 (Solar X = 521", Solar Y = 251")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 1166, was the source of a major X1.5 flare
late yesterday at 23:23 UT. 1166 developed rapidly during the
day increasing its spot count, spot area and magnetic complexity
forming a strong delta configuration within its central portion.
If the region retains its magnetic complexity, an event
=> than M5 is possible.
The position of NOAA 1166 on March 10 at 11:30 UT is:
N09W19 (Solar X = 311", Solar Y = 264")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1165, was very active yesterday
during west limb passage. It was the source of numerous C-class
events and an M4.4 event at 03/08/18:28 UT and an
M1.5 at 03/08/20:16 UT. The target will switch to NOAA 1166
today. 1166 produced an M1.7 event at 03/09/11:07 UT.
1166 has a beta-gamma-delta magnetic configuration. 1166
and former target 1164 are capable of producing M-class events.
There also remains a slight chance of a mid-level M-class event.
The position of NOAA 1166 on March 09 at 11:30 UT is:
N11W08 (Solar X = 132", Solar Y = 302")
