Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12139 has emerged new magnetic
flux in its intermediate portion over the past 24 hours, increasing
in spot area and number of spots. This region is now classified as a
beta-gamma/D-type sunspot group, but shows signs of a weak delta spot
configuration in high-resolution images. 12139 has increased in flare
productivity, being the source of 2 low C-class events since the last
message (the largest being a C1.5 flare on 15-Aug-2014 at 21:46 UT).
Further C-class activity is probable over the next 24 hours, with a
very small chance for a low M-class event if NOAA 12139 continues to
emerge new magnetic flux.
The position of NOAA 12139 on 16-Aug-2014 at 12:30 UT is:
N13E07, ( -115", 105" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12139 has maintained spot area
coverage over the past 24 hours, but has merged several spots within its
trailing portion. This region is classed as a beta/D-type sunspot group,
has increased in B-class flare productivity since the last message, and
produced a C1.1 flare on 15-Aug-2014 at 11:54 UT. Yesterday's target has
now been designated as NOAA 12141 and has continued to emerge new flux
and produce B-class flaring. Further B-class activity is expected over
the next 24 hours, with a chance for some low-to-mid C-class flares.
The position of NOAA 12141 on 15-Aug-2014 at 14:00 UT is:
N15E52, ( -726", 179" )

Dear RHESSI Collaborators,
Solar activity continues to be at a low level. NOAA 12139 has not grown
in spot area over the past 24 hours, but has increased in number of spots
(primarily in its intermediate portion). This region is still classified
as a beta/D-type sunspot group and produced the largest flare event since
the last message (a B6.3 flare on 14-Aug-2014 at 04:18 UT). A new region
emerging in the North East quadrant has also produced B-class flares and
recently formed several spots, so this emerging region is the new target.
More B-class activity is expected over the next 24 hours, with a chance
for a low-to-mid C-class flare.
The approximate position of this region on 14-Aug-2014 at 18:00 UT is:
N15E62, ( -807", 194" )

Dear RHESSI Collaborators,
Solar activity is a low level. NOAA 12139 has marginally grown in spot
area over the past 24 hours and displays a fragmented cluster of small
trailing spots. This region has remained classified as a beta/D-type
sunspot group, but may still have small scale magnetic mixing within
its intermediate portion. NOAA 12139 produced the largest event since
the last email, a B7.4 flare on 13-Aug-2014 at 11:08 UT. More B-class
activity is expected over the next 24 hours, with a chance for a low
C-class flare.
The position of NOAA 12139 on 13-Aug-2014 at 16:00 UT is:
N14E46, ( -665", 155" )

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target region NOAA
12139 has now rotated onto the visible disk to enable classification.
This region displays the characteristics of a beta/D-type sunspot group,
but may have small scale magnetic mixing in its intermediate portion
(i.e., potentially a beta-gamma classification). 12139 has continued to
be the source of B-class activity, producing two flare events since the
last email. Further B-class activity is expected over the next 24 hours,
with a chance for a low-to-mid C-class flare.
The position of NOAA 12139 on 12-Aug-2014 at 14:30 UT is:
N14E60, ( -797", 176" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA 12135 continues to be
the largest spotted region on disk, but has simplified in terms of
magnetic complexity (now classified as a beta/D-type sunspot group)
and did not produce any activity since yesterday's message. A new
region has rotated over the North East limb and was the source of
two high B-class flares. This region remains too close to the limb
to determine an accurate classification. Further B-class activity
is expected in the next 24 hours, with a chance for a low-to-mid
C-class flare.
The approximate position of this region on 11-Aug-2014 at 16:00 UT is:
N14E85, ( -915", 219" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target (12135)
has not released further activity. On the other hand NOAA
12137 has emerged as a double bipole and was responsible
for B-class activity since the previous message. Further
B-class activity is expected, with a chance for a C-class
flare.
The position of NOAA 12137 on 10-Aug-2014 17:30 UT is:
N12E12, ( -199", 95" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target was
responsible for a series of B- and C-class events,
including the largest since the last message, a C2.7
flare on 9-Aug-2014 at 08:57 UT. Flux emergence is
evident in the leading portion. Further C-class activity is
expected, with a chance for a high C-class flare.
The position of NOAA 12135 on 10-Aug-2014 18:40 UT is:
N12E18, ( -292", 98" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target was
responsible for low C-class activity and is in a state of decay.
Since its spot development yesterday, NOAA 12135 was
responsible for C-class activity, including the largest event
since the previous message, a C4.5 flare on 8-Aug-2014 at
17:01 UT. Further C-class activity is expected, with a chance
for a high C-class flare.
The position of NOAA 12135 on 8-Aug-2014 18:10 UT is:
N11E40, ( -598", 102" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12135 shows
significant spot development since the last message,
but maintains a simple configuration, is isolated, and
has not produced significant activity so far. On the
other hand, yesterday's target region (NOAA 12132)
still shows continued flux emergence in the following
portion, and was responsible for further C-class activity,
including a ~C1.5 flare that is currently in progress.
Further C-class activity is expected with the chance for
a high C-class flare.
The position of NOAA 12132 on 7-Aug-2014 18:00 UT is:
S20W31, ( 457", -406" )
