MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2521 is mostly unchanged and was
mostly quiescent producing only a minor B-class event
in the past 24 hours. The target will switch to a rapidly
developing EFR located in the northwestern quadrant.
The EFR has an east-west magnetic inversion line and bright
H-alpha plage. B-class events probable with the chance of
a C-class event if the region continues to develop.
The position of the EFR target on March 14 at 15:00 UT is:
N14W53 (Solar X = 750", Solar Y = 303")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is currently at a very low level. The background
x-ray flux is flat at B1.4. The EFR target region (now numbered
NOAA 2521) has now stabilized displaying a D-type sunspot group
with a very weak beta-gamma magnetic configuration. B-class
events possible with only a slight chance of a C-class event in the
next 24 hours.
The position of NOAA 2521 on March 13 at 15:35 UT is:
N19E09 (Solar X = -143", Solar Y = 426")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2519 is mostly unchanged in the past
24 hours. It was the source of a minor B8.8 event at
03/12/04:05 UT. The largest event since the last message
was a C1.1 event at 03/12/06:19 UT produced by NOAA
2513. The target will switch to an EFR located in the northeastern
quadrant. The EFR is displaying arch-type-filaments and
dynamic bright H-alpha plage. If it continues to develop, it might
produce a C-class event in the next 24 hour period.
The position of the target on March 12 at 15:00 UT is:
N19E23 (Solar X = -358", Solar Y = 419")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is very low. The current x-ray background
level is B1.6. Target region NOAA 2519 added a few small
spots within the trailing portion of its C-type/beta sunspot group.
B-class events possible with only a slight chance of an isolated
C-class event in the next 24 hour period.
The position of NOAA 2519 on March 11 at 06:00 UT is:
N05E65 (Solar X = -873", Solar Y = 135")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The northeastern target region, now numbered NOAA 2519,
has completed east limb passage. 2519 has been quiescent
since it produced the B- and C-class events when it was still
mostly beyond the limb. 2519 is currently displaying a simple
beta configuration with a C-type sunspot group. B-class events
possible with a slight chance of an isolated C-class event in
the next 24 hour period.
The position of NOAA 2519 on March 10 at 15:35 UT is:
N06E67 (Solar X = -885", Solar Y = 147")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The low-latitude EFR target region only produced an isolated
minor B7.1 event at 03/08/18:16 UT. The target will switch to
an active region located just beyond the northeastern limb.
The region was the source of limb occulted B- and C-class
events. The largest was a C3.3 at 03/09/12:50 UT. B- and
C-class events probable in the next 24 hours.
The approximate position of the target on March 09 at 06:00 UT is:
N05E88 (Solar X = -962", Solar Y = 088")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2512 continues in decay phase. The target will
switch to an low-latitude EFR located in the northwestern
quadrant. The EFR was the source of an isolated
C1.5 event at 03/08/13:06 UT. The region is currently
displaying a B-type/beta sunspot group. B-class events
expected with the chance of another C-class event in the
next 24 hour period.
The position of the target on March 08 at 15:00 UT is:
N02W31 (Solar X = 499", Solar Y = 138")

Dear RHESSI Collaborators,
Solar flare activity is very low. The background x-ray flux
is currently at the B1.6 level. The largest reported event
was a B2.7 at 03/06/18:04 UT produced by target region
NOAA 2512. 2512 is now decaying (especially within the
trailing portion) after displaying flux emergence yesterday.
Another B-class event possible in the next 24 hours.
The position of NOAA 2512 on March 07 at 15:35 UT is:
N11W39 (Solar X = 598", Solar Y = 276")

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12514 grew marginally
in spot area over the previous 24 hours, but remained a beta/C-type
sunspot group. NOAA 12512 initially decreased in magnetic complexity
over the same period (to an alpha/H-type sunspot group class), but
recently showed signs of flux emergence. This region has produced 6
B-class flares since the last message, including the largest event
of the period (a B7.2 on 6-Mar-2016 at 04:58 UT). B-class activity
is expected over the next 24 hours.
The position of NOAA 12512 on 6-Mar-2016 at 22:00 UT is:
N11W28, ( 449", 290" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. Previous target region NOAA
12510 has again remained stable and is classified as a beta/C-type
sunspot group. NOAA 12514 is one of three regions to be numbered in
the past 24 hours and is classified as a beta/C-type sunspot group.
B-class flares are expected over the next 24 hours.
The position of NOAA 12514 on 5-Mar-2016 at 22:00 UT is:
N14W23, ( 370", 342" )
