Dear RHESSI Collaborators,
Solar activity continues at a low level. NOAA 12529 has undergone
some decay, decreasing in both spot area and number of spots. NOAA
12529 remains the largest region on the disk but has only produced
B-class flares over the past 24 hours, including the largest event
since the last message (a B8.6 on 13-Apr-2016 at 07:35 UT). Further
B-class flares are expected over the next 24 hours, with low-to-mid
C-class flares possible.
The position of NOAA 12529 on 13-Apr-2016 at 16:00 UT is:
N09E05, ( -85", 243" )

Dear RHESSI Collaborators,
The level of solar activity continues to be low. New region NOAA
12530 has been designated as a beta/C-type sunspot group and has
been devoid of flaring activity. NOAA 12529 remains the largest
region on the visible disk and has grown marginally in spot area
and number of spots over the past 24 hours. NOAA 12529 is still
classified as a beta/E-type sunspot group and has continued to
produce C-class activity, including the largest event since the
last message (a C1.8 flare on 12-Apr-2016 at 07:40 UT). Further
C-class activity is expected over the next 24 hours.
The position of NOAA 12529 on 12-Apr-2016 at 12:00 UT is:
N09E21, ( -345", 239" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12529 remains the largest
spotted region on the visible disk over the past 24 hours and has
maintained spot area while increasing in spot number. This region
has remained a beta/E-type sunspot group, and has continued to
produce C-class activity, including the largest event since the
last message (a C1.1 flare on 11-Apr-2016 at 01:34 UT). Further
C-class activity is expected over the next 24 hours.
The position of NOAA 12529 on 11-Apr-2016 at 16:00 UT is:
N09E33, ( -519", 230" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2529 produced 10 C-class events in the past 24
hours. 2529 has increased its magnetic complexity somewhat
due to new opposite polarity flux emerging on the southeastern
edge of the large leading polarity sunspot's penumbra. C-class
events expected with a slight increase in the chances of an
isolated M-class event in the next 24 hours.
The position of NOAA 2529 on April 10 at 14:15 UT is:
N10E47 (Solar X = -692", Solar Y = 232")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2529 was the source of C-class events
in the past 24 hours. 2529 is currently displaying a large
E-type/beta sunspot group. B- and C-class events probable
with a slight chance of an M-class event in the next
24-48 hours.
The position of NOAA 2529 on April 09 at 14:15 UT is:
N10E62 (Solar X = -835", Solar Y = 212")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is currently at a very low level. Target
region, NOAA 2529, has completed east limb passage but
is still too close to the east limb to fully ascertain its magnetic
complexity but it appears to have a simple beta configuration.
B-class events probable, a C-class event is possible with a
slight chance of an M-class event in the next 24-48 hours.
The position of NOAA 2529 on April 08 at 15:15 UT is:
N10E75 (Solar X = -912", Solar Y = 191")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2528 is slowly decaying. The target will switch to a new
region located mostly beyond the northeastern limb. A large leader
sunspot has just appeared on the limb at N10 degrees. This limb
region was the source of several limb occulted B- and C-class
events since the last message. B- and C-class events expected
with a chance of an isolated M-class event in the next 24-48 hours.
The approximate position of the target on April 07 at 14:15 UT is:
N10E88 (Solar X = -943", Solar Y = 169")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The EFR located in the trailing portion of target region
NOAA 2528 developed slowly in the past 24 hours.
The region's sunspot group is now classified as a
D-type with a weak beta-gamma magnetic configuration
with an east-west magnetic inversion line. 2528 only
managed to produce minor B-class events since the last
message. The largest event in the past 24 hours was a
C1.1 produced by NOAA 2526 (S03W91) at 04/06/10:00 UT.
B-class events probable with a slight chance of an isolated
C-class event in the next 24 hour period.
The position of NOAA 2528 on April 06 at 11:15 UT is:
N07W28 (Solar X = 448", Solar Y = 208")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level. The
background x-ray flux is currently B1.2. Target
region, NOAA 2528 was the source of two minor B-class
events in the past 24 hours. The largest was an isolated
B4.6 at 04/05/07:37 UT. 2528 is displaying opposite polarity
flux emerging within the trailing portion of its B-type/beta
sunspot group. B-class events probable with a very slight
chance of an isolated C-class event if growth continues within
the trailing area.
The position of NOAA 2528 on April 05 at 14:15 UT is:
N07W17 (Solar X = 279", Solar Y = 216")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level. The
current background x-ray flux is B1.0. The recently
emerged target region is now numbered NOAA 2528.
Although 2528 has a simple C-type/beta sunspot group,
it is the most interesting region on the visible solar disk.
B-class flare activity is possible in the next 24 hours.
The position of NOAA 2528 on April 04 at 10:30 UT is:
N07W01 (Solar X = 017", Solar Y = 222")
