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:
N15E46, ( -666", 296" )

Dear RHESSI Collaborators,
The level of solar activity remains very low. A new region has rotated
over the North East limb within the past 24 hours, producing 9 B-class
flares since the last message. This region seems to have a beta/B-type
sunspot group classification. More B-class activity is expected in the
following 24 hours, with a good chance for some C-class flares.
The approximate position of this region on 26-Apr-2016 at 22:00 UT is:
N13E49, ( -701", 263" )

Dear RHESSI Collaborators,
Solar activity continues to be very low. The previous target region
has been designated as NOAA 12535 and classified as an alpha/H-type
sunspot group. Only B-class activity has occurred since yesterday's
message. More B-class activity is probable over the next 24 hours.
The position of NOAA 12535 on 25-Apr-2016 at 16:00 UT is:
N05E65, ( -863", 115" )

Dear RHESSI Collaborators,
The level of solar activity remains very low. NOAA 12532 has decayed
further since the last message, continuing to decrease in spot area
and number of spots. A currently unnumbered region has rotated over
the North East limb, producing a B1.7 flare on 24-Apr-2016 at 02:21
UT. This is most likely the return of the region that was previously
designated as NOAA 12528. Further B-class activity is probable over
the next 24 hours.
The approximate position of this region on 24-Apr-2016 at 22:00 UT is:
N07E80, ( -932", 130" )
