Dear RHESSI Collaborators,
Solar activity continues at low levels, but the background X-ray flux
is increasing gradually due to an emerging region in the northeast
quadrant. The region has been designated as NOAA 12360 and has
produced a number of low-level events over the past 24 hours. This new
target region currently has a beta configuration and is developing
rapidly. Chance for increased activity over the next day or two.
The position of NOAA 12360 on 4-Jun-2015 at 07:35 UT is:
N12E48, ( -689", 200" )

Dear RHESSI Collaborators,
NOAA 12356 has remained quiescent since the last message. A new region
rotating on to the northeast limb was the source of a C1.9 flare at
06:49 UT today and shall be the new target region. There have also
been a number of CMEs emanating from the northeast limb over the past
few days, which may also be an indicator of an impending increase in
activity. Further C-level events possible over the next 24 hours.
The approximate position of the target region on 2-Jun-2015 at 11:35 UT is:
N15E89, ( -913", 245" )

Dear RHESSI Collaborators,
Solar X-ray flux remains at background levels. The largest event since
the last message was a B6.9 flare from the target region at 03:33 UT
today. Some small satellite spots have begun to appear around the
positive polarity leader spot of NOAA 12356 and it shall continue to
be the target region. Only minor events expected at this time.
The position of NOAA 12356 on 1-Jun-2015 at 11:35 UT is:
S16E13, ( -205", -251" )

Dear RHESSI Collaborators,
Solar activity remains at a very low level. NOAA 12356 continues to be
the largest region on disk and has been reclassified as a beta/C-type
sunspot group in the past 24 hours. This region produced more B-class
activity since yesterday's message. Further B-class flares are likely
over the following 24-hour period, with a chance for a C-class event.
The position of NOAA 12356 on 31-May-2015 at 21:30 UT is:
S16E22, ( -345", -251" )

Dear RHESSI Collaborators,
The level of solar activity continues to be very low. NOAA 12356 has
remained the largest spotted region on the visible disk. This region
is classified as an alpha/H-type sunspot group and was the source of
a couple of low B-class flares since the last message. 12356 has now
developed some small pore spots in the trailing flux portion, making
it a beta magnetic classification. Further B-class activity is likely
over the next 24 hours, with a chance for an isolated C-class event.
The position of NOAA 12356 on 30-May-2015 at 20:30 UT is:
S15E36, ( -536”, -234” )

Dear RHESSI Collaborators,
Solar activity continues at a very low level. Yesterday's target is
now designated as NOAA 12356 and is the only numbered region on the
visible disk. 12356 is classified as an alpha/H-type sunspot group,
but the leading-polarity spot is in close proximity to a portion of
opposite-polarity flux from a preceding plage region. More B-class
activity is expected over the next 24 hours, with a chance for an
isolated low C-class event.
The position of NOAA 12356 on 29-May-2015 at 15:00 UT is:
S15E53, ( -730", -236" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 12353 has rotated
up to the North West limb. A new spotted region rotated over the
South East limb in the past 48 hours, but has remained unnumbered.
This region produced a C1.3 flare on 27-May-2015 at 21:22 UT and
appears to comprise of a reasonably-sized leading-polarity spot
with diffuse trailing-polarity plage. B-class activity is likely
over the next 24 hours, with a chance for an isolated low C-class
event.
The approximate position of this region on 28-May-2015 at 20:00 UT is:
S18E71, ( -851”, -287” )

Dear RHESSI Collaborators,
Solar activity remains at a very low level. NOAA 12353 continues
in decay phase, decreasing in spot area and number of spots over
the past 24 hours while maintaining a beta/C-type sunspot group
classification. NOAA regions 12349, 12351 and 12353 all produced
low-level B-class flares over the past 24 hours. Further B-class
activity is likely in the next 24 hours, with a small chance for
an isolated low C-class event.
The position of NOAA 12353 on 27-May-2015 at 12:00 UT is:
N07W66, ( 858", 124" )

Dear RHESSI Collaborators,
The level of solar activity continues to be very low. NOAA region
12353 has decayed more since yesterday's message, maintaining spot
area and decreasing in number of spots. This region is now classed
as a beta/C-type sunspot group and has again produced no flares in
the past 24 hours. B-class flares are probable in the following 24
hours, with a chance for an isolated low C-class event.
The position of NOAA 12353 on 26-May-2015 at 14:30 UT is:
N07W53, ( 753", 129" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA 12353 has shown further
signs of decay since yesterday’s message. This region has maintained
a beta/D-type sunspot group designation, but has not been the source
of any flaring over the past 24 hours. B-class flares are expected
in the following 24-hour period, with a chance for an isolated low
C-class event.
The position of NOAA 12353 on 25-May-2015 at 16:00 UT is:
