Dear RHESSI Collaborators,
Solar X-ray flux has remained constant around the B2 level since the
last message. The target region NOAA 12544 has remained quiescent and
continues to decrease in both size and complexity as it approaches the
western limb. No significant activity expected over the next 24 hours.
The position of NOAA 12544 on 19-May-2016 at 17:17 UT is:
N21W65, ( 803", 353" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The trailing portion of
target region NOAA 12544 has completely decayed and the region remains
quiescent. No significant activity is expected over the next 24 hours.
The position of NOAA 12544 on 18-May-2016 at 20:20 UT is:
N22W53, ( 703", 376" )

Dear RHESSI Collaborators,
Solar X-ray flux remains steady at the mid B-level. The only C-class
flare since the last message was a C1.2 flare from NOAA 12542. The
trailing portion of NOAA 12544 continues to decay but the region
retains some overall polarity mixing and shall remain the target
region. Only isolated low-level events expected at this time.
The position of NOAA 12544 on 17-May-2016 at 17:17 UT is:
N20W37, ( 537", 354" )

Dear RHESSI Collaborators,
Solar activity has returned to low levels with only a C1.9 flare since
the last message. The target region NOAA 12544 has continued to decay
but is now classified as a beta-gamma region. Chance for additional
isolated C-class flares over the next 24 hours.
The position of NOAA 12544 on 16-May-2016 at 22:00 UT is:
N20W27, ( 406", 359" )

Dear RHESSI Collaborators,
Solar activity continues to increase with numerous C-class events
emanating from various active regions. NOAA 12542 (N10W77) was
the source of a long-duration event (a C3.4 at 15:00 UT on May 15)
due to a filament eruption and accompanied by a beautiful standard
CME. Yesterday's target region NOAA 12543 (S05W82) produced
several C-class flares including the largest one (a C5.4 at 03:58 UT
on May 15). NOAA 12544 was the source of 7 low C-class flares and
also a few B-class events. NOAA 12543 is rotating to the west limb,
and has lost some of its magnetic complexity. Today we will watch
NOAA 12544 that has a beta/D-type sunspot group. Further C-class
activities are expected over the next 24 hour period.
The position of NOAA 12544 on May 15 at 21:17 UT is:
N21W13 (200", 379")

Dear RHESSI Collaborators,
Solar activity has increased since the last message with
numerous B- as well as C-class events emanating from
various regions. NOAA 12544 (N21W00) and yesterday's
target region NOAA 12542 (N10W61) were the sources
of a few B-class flares. NOAA 12543 produced all the four
C-class events, including the largest one, a C8.4 at 11:28 UT
on May 14. Today the target region will switch to 12543 that
has a beta/D-type sunspot group. Additional C-class activities
are likely in the next 24 hours.
The position of NOAA 12543 on May 14 at 19:17 UT is:
S05W65 (858", -64")

Dear RHESSI Collaborators,
Solar activity continues to be very low. The largest event since
the last message was a B7.4 at 16:16 UT on May 13 produced
by NOAA 12544 (N20E11) due to a filament eruption. The target
region NOAA 12542 only produced several low-level B-class
events. 12542 is now classified as a D-type/beta-gamma magnetic
configuration with increasing in sunspot area slightly. B-class
activities are expected, with a chance of C-class events in the
next 24 hour period.
The position of NOAA 12542 on May 13 at 17:17 UT is:
N10W46 (674", 196")

Dear RHESSI Collaborators,
Solar activity has been very low with GOES soft X-ray flux below
the C-level. Target region NOAA 12542 was the source of a few
minor B-class events. 12542 has lost some of its magnetic complexity,
and is now classified as a beta/C-type sunspot group. It continues to
show mixed polarities at the edge of the main negative spot. B-class
flares are expected, with a chance of minor C-class events in the next
24 hours.
The position of NOAA 12542 on May 12 at 18:17 UT is:
N11W34 (522",220")

Dear RHESSI Collaborators,
Solar activity has been at very low levels since the last message.
Target region NOAA 12542 was the source of several B-class events,
the largest being a B8.2 at 14:14 UT on May 11. 12542 was reclassified
as a C-type region but remaining its complex beta-gamma magnetic
configuration. It is displaying bright H-alpha plage and surges, with the
potential to produce some low C-class activities.
The position of NOAA 12542 on May 11 at 17:43 UT is:
N12W22 (349",243")

Dear RHESSI Collaborators,
Solar activity continues at a very low level. The target region
NOAA 12542 was the source of several B-class events due
to filament interaction and eruption. 12542 has been classified
as a complex D-type/beta-gamma magnetic configuration with
increasing in sunspot area and number of spots significantly.
It is continuously showing positive flux emergence at the edge
of the main negative spot. C-class activities are likely in the
next 24 hours.
The position of NOAA 12542 on May 10 at 21:43 UT is:
N12W10 (161",247")
