Dear RHESSI Collaborators,
The level of solar activity is now medium. NOAA region 11176 has a
beta magnetic classification and displays a highly elongated second
umbra. However, it is too close to the limb to be able to accurately
determine the degree of polarity mixing and hence its configuration.
This region produced an M1.4 flare at 02:03 UT on 23-Mar-2011.
C-class activity is probable, with a small chance of another M-class
flare.
The position of NOAA 11176 on 23-Mar-2011 at 10:30 UT is:
S14E63, ( -835", -181" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11176 has rotated over the
SE limb and is the disk passage return of previously numbered NOAA
11165. This region has been the source of several C-class events, the
largest of which was a C4.2 flare on 21-Mar-2011 at 15:31 UT. Further
C-class activity is probable.
The position of NOAA 11176 on 22-Mar-2011 at 10:30 UT is:
S13E75, ( -908", -186" )

Dear RHESSI Collaborators,
The level of solar activity continues to be very low. NOAA region 11175
has grown in area coverage, but maintains its number of spots and beta
magnetic classification. B-class activity is expected.
The position of NOAA 11175 on 21-Mar-2011 at 10:30 UT is:
N14W42, ( 624", 317" )

Dear RHESSI Collaborators,
Solar activity remains at a very low level. NOAA region 11175 has grown
slightly in area and number of spots over the past 24 hours. The speed
of this continued evolution indicates a significant slow-down on its rapid
emergence. B-class activity is possible.
The position of NOAA 11175 on 20-Mar-2011 at 11:00 UT is:
N14W28, ( 441", 334" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA region 11173 has decreased
in area coverage and number of spots since yesterday's message. New
NOAA region 11175 exhibits a beta magnetic configuration. B-class activity
is expected, with a chance for C-class events if 11175 continues its rapid
emergence.
The position of NOAA 11175 on 19-Mar-2011 at 16:00 UT is:
N13W18, ( 288", 326" )

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")
