Dear RHESSI Collaborators,
Solar activity continues at low levels. The only event of note since
the last message was a B4.2 flare from NOAA 12554 at 13:00 UT today.
NOAA 12554 has shown signs of decay in its trailing portion as it
approaches the western limb but it shall be the new target region for
the next 24 hours. Isolated low-level events possible before west limb
passage.
The position of NOAA 12554 on 15-Jun-2016 at 05:45 UT is:
N08W75, ( 904", 126" )

Dear RHESSI Collaborators,
NOAA 12552 has now rotated over the western limb, although its
looptops are still visible in SDO/AIA images. As the remaining active
regions on the visible solar disk have been predominantly quiescent
since the last message, NOAA 12552 shall remain the target region for
a further 24 hours. Also include NOAA 12554 in your field of view if
possible as it has produced some B-level activity in the past few
days. Slight chance of an isolated low level event from the northwest
limb.
The approximate position of NOAA 12552 on 14-Jun-2016 at 05:45 UT is:
N14W91, ( 915", 228" )

Dear RHESSI Collaborators,
NOAA 12552 has continued producing B-level activity as it approaches
the western limb, along with a C3.0 flare at 05:33 UT today. The
region's magnetic configuration is unclear from this angle but it
shall remain the target region for an additional 24 hours as it
transits the western limb. Further low-to-intermediate level activity
possible.
The position of NOAA 12552 on 13-Jun-2016 at 08:31 UT is:
N14W91, ( 915", 228" )

Dear RHESSI Collaborators,
The target region NOAA 12552 was the source of a C6.5 flare at 21:59
UT yesterday. The region has begun to decay as it approaches the
western limb, and appears to have lost some of its complexity. NOAA
12552 shall remain the target region for the next 24 hours. Sustained
B-level activity expected with chance for an isolated low C-class
flare before west limb passage.
The position of NOAA 12552 on 12-Jun-2016 at 11:31 UT is:
N15W82, ( 903", 242" )

Dear RHESSI Collaborators,
Solar activity continues at the B-level, with most activity coming
from NOAA 12552. The new region on the eastern limb has been
designated as NOAA 12553 but has remained quiescent. NOAA 12552
retains its beta-delta configuration and shall remain the target
region. Further low-level activity likely.
The position of NOAA 12552 on 11-Jun-2016 at 14:31 UT is:
N14W71, ( 867", 225" )

Dear RHESSI Collaborators,
Solar activity has been at the B-level since the last message, despite
the appearance of a large sunspot on the eastern limb. NOAA 12552
continues to develop and is now classified as a beta-delta region. It
shall remain the target for a further 24 hours with chance for
additional low level events.
The position of NOAA 12552 on 10-Jun-2016 at 17:31 UT is:
N15W58, ( 775", 240" )

Dear RHESSI Collaborators,
Solar activity has increased since the last message due to the
continued development of the target region NOAA 12552. The region has
increased in both size and complexity, and was the source of two C1
flares as well as several B-level events. It is currently classified
as a beta region but is showing signs of polarity mixing in its core.
Additional C-level activity expected over the next 24 hours.
The position of NOAA 12552 on 9-Jun-2016 at 14:45 UT is:
N17W44, ( 629", 272" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. A newly emerged active region
in the northwest quadrant, designated as NOAA 12552, has increased the
background X-ray flux level and was the source of a B2.3 flare at
04:04 UT today. The region has a beta magnetic configuration and is
emerging into the decaying plage of a former region. Chance for
further isolated low level events as the region evolves.
The position of NOAA 12552 on 8-Jun-2016 at 11:45 UT is:
N16W29, ( 441", 257" )

Dear RHESSI Collaborators,
The Sun remains spotless with the X-ray flux staying constant at the
B1 level. The new target region shall be the large filament in the
northwest quadrant. No significant activity expected over the coming
days unless the filament becomes unstable and erupts.
The approximate position of the target region on 6-Jun-2016 at 20:30 UT is:
N09W40, ( 601", 147" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues extremely low. The background
x-ray flux is flat at the B1.0 level. The visible solar disk
is spotless again today. The activation phase of the target
filament died away and the filament is currently stable.
The target will switch to the large decaying plage and its
filament located along the region's magnetic inversion line.
No significant solar activity expected anytime soon.
The position of the target on June 05 at 07:45 UT is:
N12E20 (Solar X = -318", Solar Y = 199")
