Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 12335 continues
to be the largest spotted region on the visible disk. This region
has undergone minor flux emergence over the past 24 hours and is
classified as a beta/D-type sunspot group, although it appears to
exhibit magnetic polarity mixing in its intermediate portion (i.e.
a beta-gamma configuration). NOAA 12335 has maintained flaring at
the C-class level, producing 6 low C-class flares and the largest
event in the previous 24 hours (a C8.0 on 4-May-2015 at 00:43 UT).
Further C-class activity is expected in the next 24 hour period.
The position of NOAA 12335 on 4-May-2015 at 18:00 UT is:
S16E27, ( -418", -208" )

Dear RHESSI Collaborators,
Solar activity is at low levels. The target region NOAA 12335 was the
source of 5 C1 and 4 high B-level events since the last message.
There was a QS-filament eruption at ~16:30 UT yesterday across the
southern hemisphere, which was associated with a two-ribbon flare and
a halo CME. NOAA 12335 maintains its D-type/beta-gamma magnetic
configuration, increasing its spot area and count. It continues to show
mixed polarities in its intermediate portion. Low level activity is expected
in the next 24 hours.
The position of NOAA 12335 on May 3 at 15:35 UT is:
S15E43 (Solar X = -628", Solar Y = ,-200")

Dear RHESSI Collaborators,
Solar activity has been at very low levels for the past 24 hours with X-ray
flux below the C-level. The target region NOAA 12335 is the only region
with sunspots on the visible solar disk. 12335 has a D-type/beta-gamma
magnetic configuration. It is showing some mixed polarities in its leading
portion. C-class activity is likely in the next 24-48 hours.
The position of NOAA 12335 on May 2 at 15:35 UT is:
S15E54 (Solar X = -745", Solar Y = -208")

Dear RHESSI Collaborators,
Solar activity is very low. NOAA 12335 was the source of three low-
level (C1.1, C1.1, and C2.3) events as it rotated onto the visible disk.
The unnumbered region, located between two large filaments, has been
designated as NOAA 12334 (S19E02). The two filaments are still visible
across the southern hemisphere, which might erupt in the next few days.
Today we switch the target region to NOAA 12335. It has increased
unsigned flux as well as current helicity (from SHARP data). Low-level
activity expected in the next 24 hours.
The position of NOAA 12335 on May 1 at 15:35 UT is:
S15E67 (Solar X = -847", Solar Y = -220")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The largest X-ray event since
the last message was a C1.0 at 16:20 UT yesterday from the limb region
NOAA 12327 (S08W90). The visible solar disk is basically spotless. We
continue to watch the unnumbered region, but close to its left filament.
The right filament has been oscillating and may disappear. No significant
activity is expected.
The position of the target on April 30 at 11:35 UT is:
S23E21 (Solar X = -300”, Solar Y = -320”)

Dear RHESSI Collaborators,
Solar activity is at very low levels with GOES X-ray flux flat at B3 level.
Yesterday's target region NOAA 12331 is rotating over the west limb, so
is NOAA 12327. Another active region NOAA 12333 is visible on the solar
disk, but shows a simple alpha configuration. There is an unnumbered
small region in the southeast quadrant, which seems to connect two large
filaments. Today we switch the target to this unnumbered region. There is
a chance of filament eruption in the next few days.
The position of target region on April 29 at 11:35 UT is:
S19E32 (Solar X = -500”, Solar Y = -280”)

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The largest event since the
last message was a C1.9 at 05:13 UT today produced by the target
region NOAA 12331. The large filament at the northeast limb was erupted
at ~14:00 UT today, which was associated with a two-ribbon flare and
a CME. NOAA 12331 has been downgraded to a beta region. It will be
the primary target for one more day, with low-level activity possible in the
next 24 hours. NOAA 12333 (N20W09) shows some signs of growth,
with a chance of low-level activity.
The position of NOAA 12331 on April 28 at 15:35 UT is:
S09W82 (Solar X = 932", Solar Y = -138")

Dear RHESSI Collaborators,
Solar activity is at very low levels. The largest X-ray event since the last
message was a C1.4 at 20:51 UT yesterday produced by NOAA 12327.
There is a large filament currently visible near the northeast limb. The
target region NOAA 12331 produced a small filament eruption at 21:42
UT yesterday, which was associated with a small CME toward the south-
west direction. 12331 retains its D-type/beta-gamma configuration with
increasing in spot area. It continues to be today's target region. If
possible, also include 12327 (S08W58) within your field of view. Very
low-level activity is expected over the next 24 hours.
The position of NOAA 12331 on April 27 at 15:35 UT is:
S10W68 (Solar X = 871", Solar Y = -137")

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the last
message was a C1.9 at 18:03 UT yesterday from the northwest limb.
The target region NOAA 12331 was the source of two C1 events today.
12331 maintains its D-type/beta-gamma magnetic configuration. It shows
some flux emergence in its trailing portion. Low-level activity is likely in
the next 24 hours.
The position of NOAA 12331 on April 26 at 11:35 UT is:

Dear RHESSI Collaborators,

a D-type/beta-gamma magnetic classification. Low-level activity is expected
over the next 24 hour period.
The position of NOAA 12331 on April 25 at 15:35 UT is:
