Dear RHESSI Collaborators,
Solar activity is very low with the soft X-ray flux at the background
level. The visible disk remains spotless. Nevertheless, the plage region
NOAA 12661 shows some small eruptions, one of which might be
associated with a very weak CME. 12661 is rotating over the west limb.
Only low activities are possible in the next 24 hours.
The position of NOAA 12661 on June 12 at 15:30 UT is:
N07W76 (910", 112")

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target region
has rotated into view and is a small unspotted plage region with no
notable evolution since the last message. The target will return to
the decayed plage that was previously NOAA 12661, which has again
produced the only flare of the past 24 hours (a B1.5 on 11-Jun-2017
at 01:07 UT). Further low B-class flares are possible over the next
24-hour period.
The approximate position of this region on 11-Jun-2017 at 21:30 UT is:
N07W64, ( 844", 111" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA 12661 has been confirmed
as having decayed into spotless plage. A new magnetic region is now
rotating over the South East limb. Although it is unknown if this
region consists of sunspots or only plage fields, it will become the
new target. B-class activity is possible over the next 24 hours.
The approximate position of this region on 10-Jun-2017 at 21:30 UT is:
S06E90, ( -939", -99" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12661 has decayed more
in the past 24 hours. Although 12661 was designated as a alpha/A-type
sunspot group at the start of the UT day, it has now lost all of its
spots. This region was the source of the only flare since the last
email, a B4.1 on 9-Jun-2017 at 11:52 UT. B-class activity is possible
over the following 24-hour period.
The position of NOAA 12661 on 9-Jun-2017 at 19:30 UT is:
N07W33, ( 510", 110" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. Decaying NOAA 12661 lost more
spot area and numbers of spots in the past 24 hours. This region is
now designated as a simple alpha/H-type sunspot group and produced the
largest flare since the last email (a B2.9 on 8-Jun-2017 at 03:38 UT).
Further B-class activity is possible in the next 24 hours.
The position of NOAA 12661 on 8-Jun-2017 at 19:30 UT is:
N07W22, ( 350", 111" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12661 continues in its decay
phase, decreasing further in both area and number of spots. 12661 is
now classed as a beta/C-type sunspot group and was the source of the
largest flare since the last email (a C1.3 on 7-Jun-2017 at 02:12 UT).
B-class flares are expected in the next 24 hours, with a good chance
for additional low C-class events.
The position of NOAA 12661 on 7-Jun-2017 at 19:30 UT is:
N06W12, ( 193", 97" )

Dear RHESSI Collaborators,
Solar activity is at a low level. The decay of NOAA 12661 continues,
the region decreasing in both area and number of spots over the past
24 hours. NOAA 12661 was classified as a beta-delta/E-type sunspot
group at the start of the UT day, but currently appears to have no
delta spot. B-class activity is expected in the following 24 hours,
with a chance for low-to-mid C-class events.
The position of NOAA 12661 on 6-Jun-2017 at 19:30 UT is:
N06E02, ( -36", 99" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12661 has continued to decay
over the past 24 hours, decreasing in spot area and in classification
to a beta/E-type sunspot group. Since the last message NOAA 12661 has
produced 4 B-class events and a C2.7 flare on 5-Jun-2017 at 05:14 UT,
the largest event in the period. B-class flares are expected over the
next 24 hours, with a good chance for more low-to-mid C-class events.
The position of NOAA 12661 on 5-Jun-2017 at 21:00 UT is:
N06E14, ( -234", 100" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2661 has significantly decayed within its leading
sunspots but the trailing sunspots are maintaining
a moderate sized sunspot with weak mixed polarity.
2661 was the source of B- and C-class events in the
past 24 hours. B- and C-class events probable with the
chance of an isolated M-class event in the next 24 hour period.
The position of NOAA 2661 on June 04 at 12:45 UT is:
N06E37 (Solar X = -568", Solar Y = 102")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2661 is now decaying within its leading polarity area
but is maintaining an E-type/beta-gamma sunspot group.
The weak mixed polarities are located within its intermediate
and trailing portions. 2661 was the source of B- and C-class
activity during the past 24 hours. The largest event was a
C8.0 at 06/02/17:57 UT. B- and C-class events probable
with a slight chance of an isolated M-class event in the
next 24 hour period.
The position of NOAA 2661 on June 03 at 14:30 UT is:
N06E48 (Solar X = -701", Solar Y = 103")
