Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA region 11775 has decreased
slightly in spot area and number of spots and been reclassified by NOAA
to a beta-delta/D-type sunspot group. This region shows some signs spot
migration and flows between opposite polarities, but produced no flares
in the past 48 hours. Yesterday's target region behind the South East
limb is now rotating onto the visible disk, showing at least one large
mature sunspot. No estimate is made of …
[View More]its magnetic classification, due
to proximity to the limb. This region has continued to produce flares,
being the source of a C1.9 flare on 20-Jun-2013 at 09:13 UT. Further
C-class activity is probable, with a small chance for an isolated low
M-class event.
The approximate position of this region on 20-Jun-2013 at 12:00 UT is:
S15E85, ( -908", -247" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. Yesterday's target NOAA region 11775
has increased marginally in spot area and significantly in number of spots,
but has produced no further flares since yesterday's message. This region
is
now classified by NOAA as a beta/D-type sunspot group, but still shows
signs
of a delta spot in one of the main leading spots. The new region beyond the
South East limb has produced an additional two (partially occulted) C-class
flares, with …
[View More]the largest being a C8.4 on 19-Jun-2013 at 09:33 UT. The
target
changes to this region due to the increased magnitude and rate of flaring.
Further C-class activity is probable, with a small chance for a low M-class
event.
The approximate position of this region on 19-Jun-2013 at 10:30 UT is:
S13E90, ( -920", -212" )

Dear RHESSI Collaborators,
The level of solar activity remains low. The largest event in the past
24 hours was a C2.4 flare on 18-Jun-2013 at 00:40 UT, which origintated
from an active region located beyond the South East limb. This region
has no known flaring history, as it is not a returning NOAA region with
having emerged on the far-side of the Sun. NOAA 11775 has increased in
spot area and number of spots over the past 24 hours, while increasing
in complexity to a beta-delta/D-type sunspot …

region has continued to produce C-class events, including a C1.3 flare
on 18-Jun-2013 at 05:35 UT. Further C-class activity is probable in the

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 11775 is classified by
NOAA as a beta/D-type sunspot group, and has produced two C-class events
in the previous 24 hours (the largest being a C1.2 flare on 17-Jun-2013 at
02:53 UT). This region has continued to emerge new magnetic flux, resulting
in the formation of a second leading positive-polarity spot and additional
intermediate negative-polarity spots. Further C-class activity is probable
in the following 24 …

Dear RHESSI Collaborators,
Solar activity remains at low levels. There has been number of B-class
flares over the past 24 hours from both NOAA 11768 and a new region on the
southeast limb, NOAA 11775. The magnetic configuration of NOAA 11775 is
unclear at this time so NOAA 11768 shall remain the target region for an
additional 24 hours with further low-level activity expected.
The position of NOAA 11768 on 16-Jun-2013 at 05:00 UT is:
S11W62, ( 819", -189" )

Dear RHESSI Collaborators,
Solar activity remains at low levels. The cluster of active regions in the
southwest quadrant have been the source of some B- and C-class flares over
the past 24 hours. The target region NOAA 11768 continues to develop but
has remained quiescent. It maintains its beta/D-type magnetic configuration
and may still produce some isolated low-level events.
The position of NOAA 11768 on 15-Jun-2013 at 05:00 UT is:
S11W49, ( 701", -191" )

Dear RHESSI Collaborators,
The source of yesterday's B-class flares on the southeast limb has now been
identified as NOAA 11769 and 11770, both of which appear to be small and
static. However, a rapidly emerging region in the southwest quadrant, NOAA
11768, has also produced some B-level activity and continues to show signs
of flux emergence and shall be the new target region. The region currently
has a beta/D-type magnetic configuration and may produce some C-level
activity over the next 24 …

The position of NOAA 11768 on 14-Jun-2013 at 09:00 UT is:

Dear RHESSI Collaborators,
NOAA 11765 has remained quiescent as it rotates over the western limb. A
new, unnumbered region on the southeast limb was the source of a number of
occulted low B-class flares since the last message and shall be the new
target region. The region's magnetic configuration is uncertain at this
time but more low level events are possible as the region rotates into view.
The position of the target region on 13-Jun-2013 at 09:00 UT is:
S20E89, ( -887", -323" )

Dear RHESSI Collaborators,
Solar activity is at very low levels with the GOES X-ray flux consistently
below the B2 level over the past 24 hours. NOAA 11765 continues to decay as
it approaches the western limb. No significant activity expected at this
time.

Dear RHESSI Collaborators,
Solar activity remains at low levels. The target region NOAA 11765 was the
source of a flurry of B-class flares yesterday including a C1.9 flare at
14:18 UT. It has since remained quiescent and has begun to decay on
approach to the western limb. Chance for isolated low level events over the
next 24 hours.
