Dear RHESSI Collaborators,
The level of solar activity is very low with only several minor
B-class events emanating from NOAA 12539 and 12541. The
target region NOAA 12542 remains its beta/C-type configuration
but decreasing in sunspot area. 12542 continues to show mixed
polarities in its trailing portion, and is surrounded by some small
filaments. C-class activities are possible in the next 24 hour period.
The position of NOAA 12542 on May 6 at 15:43 UT is:
N10E47 (-686",204")

Dear RHESSI Collaborators,
Solar activity continues to be very low. The largest event since
the last message was a C1.7 at 22:43 UT on May 4 produced
by the new limb region (now designated as NOAA 12542). 12542
was classified as a beta/C-type sunspot group (but seems to have
a beta-gamma configuration). It is showing some mixed polarities
in its trailing positive spot. Further C-class flares are expected in
the next 24 hours.
The position of NOAA 12542 on May 5 at 19:43 UT is:
N09E58 (-798",180")

Dear RHESSI Collaborators,
Solar activity is at a very low level. The largest event since the last
message is a C1.3 at 13:41 UT on May 4, associated with a CME,
produced by NOAA 12535 (N07W65). There were some B-class
events emanating from NOAA 12541 as well as a new limb region.
Yesterday's target NOAA 12539 has been flare quiet over the past
24 hours. Today the target will switch to NOAA 12541 that has a
beta/C-type sunspot group. 12541 is displaying some opposite
polarity flux emergence in its leading spot. If possible, also include
the new limb region (N12E88) within the field-of-view. C-class
activities are expected in the next 24-48 hours.
The position of NOAA 12541 on May 4 at 16:43 UT is:
N04E42 (-636",112")

Dear RHESSI Collaborators,
The level of solar activity is very low. The target region NOAA 12539
was the source of the largest event (a B6.4 at 00:54 UT on May 3)
in the past 24 hours. 12539 is remaining a beta/E-type classification
with slightly decreasing in sunspot area and number of spots. Only
very low activities are expected in the next 24 hour period.
The position of NOAA 12539 on May 3 at 15:43 UT is:
N16W02 (Solar X = 32", Solar Y = 324")

Dear RHESSI Collaborators,
Solar activity continues to be low. The target region NOAA 12539
was the source of a C2.5 (at 23:30 UT on May 1) and several B-
class events in the past 24 hours. 12539 has been classified as
a beta/E-type configuration with increasing in sunspot area and
number of spots. Another region, NOAA 12540 (N21E29), produced
the largest event, a C3.5 at 08:32 UT on May 2 associated with a
narrow CME. If possible, also include 12540 within the field-of-view.
Additional C-class activities are possible in the next 24 hours.
The position of NOAA 12539 on May 2 at 15:43 UT is:
N16E13 (Solar X = -206", Solar Y = 324")

Dear RHESSI Collaborators,
Solar activity continues to be at a low level. NOAA 12539 has grown
in spot area and number of spots over the past 24 hours. This region
has remained classified as a beta/C-type sunspot group, and produced
the largest event since the last message (a C2.4 flare on 1-May-2016
at 09:14 UT). Further C-class flares are possible over the following
24 hours.
The position of NOAA 12539 on 1-May-2016 at 22:00 UT is:
N17E26, ( -400", 337" )

Dear RHESSI Collaborators,
The level of solar activity continues to be low. NOAA 12537 began to
decay over the past 24 hours but remains classified as a beta/D-type
sunspot group. Newly numbered region NOAA 12539 produced the largest
flare since the last message, a C1.2 on 30-Apr-2016 at 10:40 UT. This
region was initially classified as a beta/C-type sunspot group but it
now appears to have some magnetic polarity mixing (i.e., a beta-gamma
classification). C-class flares are probable over the next 24 hours.
The position of NOAA 12539 on 30-Apr-2016 at 20:30 UT is:
N17E40, ( -584", 329" )

Dear RHESSI Collaborators,
Solar activity has returned to a very low level. NOAA 12535 slowed in
its growth and has been confirmed as a beta/C-type sunspot group over
the past 24 hours. This region produced a B3.4 flare shortly after the
last message (on 28-Apr-2016 at 23:18 UT) but has remained flare quiet
otherwise. NOAA 12537 has grown in sunspot area over the past 24 hours,
and is classified as a beta/D-type sunspot group. This region produced
two B-class flares since the last message, including the largest event
of the period (a B6.2 on 29-Apr-2016 at 03:51 UT). More B-class flares
are expected over the following 24 hours.
The position of NOAA 12537 on 29-Apr-2016 at 16:00 UT is:
S07W74, ( 909", -96" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12536 grew somewhat in spot
area and number of spots over the previous 24 hours. This region has
remained classed as a beta/D-type sunspot group and was flare-quiet
since the last message. NOAA 12535 also grew marginally and produced
4 C-class flares, including the largest magnitude event of the period
(a C1.9 on 28-Apr-2016 at 12:46 UT). Although this region was earlier
classed as an alpha/H-type sunspot group, it appears to be at least a
beta/C-type classification now. More C-class flares are probable over
the next 24 hours.
The position of NOAA 12535 on 28-Apr-2016 at 23:00 UT is:
N06E17, ( -282", 169" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. Yesterday's target region has
been numbered as NOAA 12536 and has been designated as a beta/D-type
sunspot group classification. This region has grown in spot area and
number of spots since the last message and produced 3 B-class flares,
including the largest magnitude event of the period (a B7.2 flare on
27-Apr-2016 at 03:47 UT). Further B-class flares are expected in the
next 24 hours, with a good chance for C-class flares.
The position of NOAA 12536 on 27-Apr-2016 at 16:00 UT is:
