Dear RHESSI Collaborators,
Solar activity continues to be at a very low level. After appearing
to decay slightly after yesterday's message, NOAA 12578 was classed
as an alpha/A-type sunspot group. This region has since shown signs
of minor growth and consolidation in its leading polarity spots. No
significant flares have been produced by 12578 since the last email.
B-class activity is possible over the next 24-hour period.
The position of NOAA 12578 on 18-Aug-2016 at 21:30 UT is:
N09E21, ( -338", 44" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12578 has remained a
small bipolar beta/B-type sunspot group, with extended leading and
trailing plage field regions. NOAA 12578 produced one of the only
two B-class flares since the last message and will continue as the
target region because of some polarity mixing between the trailing
plage and a minor leading spot. More B-class activity is possible
over the following 24 hours.
The position of NOAA 12578 on 17-Aug-2016 at 22:00 UT is:
N08E37, ( -564", 42" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. Yesterday's target has been
designated as NOAA 12578 and is classified as a beta/C-type sunspot
group. This region was the source of the only flare since the last
message, a B8.1 on 16-Aug-2016 at 08:08 UT. Further B-class flares
are possible in the next 24 hours, with a chance for a low C-class
flare.
The position of NOAA 12578 on 16-Aug-2016 at 22:00 UT is:
N08E49, ( -708", 59" )

Dear RHESSI Collaborators,
The level of solar activity is low. A new region has rotated over
the North East limb since the last message and was the source of
multiple B-class events and two C1.1 flares. This region appears
to have a beta magnetic class, with fairly extended leading and
trailing plage field regions. More B-class activity is expected
in the following 24-hour period, with a chance for another low
C-class flare.
The approximate position of this region on 15-Aug-2016 at 22:00 UT is:
N08E62, ( -828", 79" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels with only sporadic B-class
flares since the last message. Both NOAA 12573/12574 and NOAA 12577
retain their bipolar configurations but are both in decay. NOAA
12573/12574 shall continue to be the target region but include NOAA
12577 in your field of view if possible. Further isolated low-level
events possible.
The position of NOAA 12573/12574 on 14-Aug-2016 at 17:31 UT is:
N05W14, ( 229", -23" )

Dear RHESSI Collaborators,
B-level activity continues from the cluster of active regions
approaching disk center. Both the target region NOAA 12573/12574 and
NOAA 12577 maintain their beta configuration and do not exhibit any
significant signs of development. Further low-level events likely.
Include both regions in your field of view if possible.
The position of NOAA 12573/12574 on 13-Aug-2016 at 17:31 UT is:
N04W03, ( 49", -42" )

Dear RHESSI Collaborators,
The target region NOAA 12573/12574 has produced sustained B-level
activity over the past 24 hours. The region to the east - NOAA 12577 -
also produced a B4.8 flare at 11:53 UT today. NOAA 12573/12574
maintains its beta configuration and sunspot area. Further B-level
events expected. Also include NOAA 12577 in your field of view if
possible.
The position of NOAA 12573/574 on 12-Aug-2016 at 17:31 UT is:
N04E11, ( -180", -40" )

Dear RHESSI Collaborators,
The target region NOAA 12573/12574 has produced several low level
events since the last message as well as a C2.4 flare at 16:32 UT
today. The region has remained unchanged in terms of size and
complexity. Further B-level activity possible with chance for an
additional isolated C-class event.
The position of NOAA 12573/12574 on 11-Aug-2016 at 17:31 UT is:
N05E25, ( -400", -14" )

Dear RHESSI Collaborators,
Solar activity has decreased to the B-level. The target region NOAA
12573 has been the source of most of the activity since the last
message. The region appears to be in decay although still exhibits
signs of rotational motion. A new bipolar region has also emerged
close to the trailing edge of the target region. Further low level
events likely with chance for an isolated C-class flare.
The position of NOAA 12573 on 10-Aug-2016 at 17:31 UT is:
N05E39, ( -595", 0" )

Dear RHESSI Collaborators,
Solar activity continues at the C-level, with the largest event since
the last message being a C8.9 flare at 00:34 UT today from the new
target region. NOAA 12573 retains its beta configuration but appears
to have ceased undergoing development. The trailing spot is exhibiting
a rotational behavior which could lead to further intermediate level
activity over the next 24 hours.
The position of NOAA 12573 on 9-Aug-2016 at 14:31 UT is:
S01E65, (-861", -60")
