Dear RHESSI Collaborators,
Solar activity has been at low levels, with numerous C1 events emanating
from the solar disk since the last message. Yesterday's target region
NOAA 12326 has rotated over the west limb. NOAA 12331 has a complex
D-type/beta magnetic configuration, showing some flux emergence in both
the leading and trailing portions. It will be today's target region.
Low activity
is possible in the next 24 hours.
The position of NOAA 12331 on April 24 at 11:35 UT is:
S09W26 (Solar X = 414", Solar Y = -77")

Dear RHESSI Collaborators,
Solar activity has been at low-to-intermediate levels since the last
message. The largest event was a long duration M1.1 event at
09:18 UT today from the northwest limb (N07W80). NOAA 12326
was the source of a few low C-class events as well as a C7.3 at
11:58 UT today. 12326 has developed rapidly over the past 24 hours.
It will be today's target region. Further low-level activity is likely in the
next 24 hours.
The position of NOAA 12326 on April 23 at 11:35 UT is:
N15W76 (Solar X = 894", Solar Y = 265")

Dear RHESSI Collaborators,
Solar activity has been at moderate-to-low levels over the past 24
hours. The target region NOAA 12322 was the source of 5 low M-
class and several C-class events since the last message, the largest
one being an M4.0 at 15:24 UT yesterday. 12322 will be the target
region for one more day, with a chance of further occulted activity.
NOAA 12324 (N19W42) also has the potential to produce low-level
activity, with some positive flux emerging from its negative leading
spot.
The position of NOAA 12322 on April 22 at 15:35 UT is:
N11W91 (Solar X = 936", Solar Y = 179")

Dear RHESSI Collaborators,
Solar activity has increased significantly in the last a few hours. Three
low M-class events emanated from the solar disk, an M2.2 at 10:17 UT
from the northeast limb (N16E80), and two occulted events (an M1.0 at
07:08 UT and an M2.2 at 11:49 UT) from NOAA 12322. NOAA 12322
has developed rapidly over the last 24 hours, though with a C-type/beta
configuration and small spot area and count. Because of its activity
history, we switch the target region to 12322 today. Additional occulted
activity is likely in the next 24 hours.
The position of NOAA 12322 on April 21 at 11:35 UT is:
N11W78 (Solar X = 917", Solar Y = 198")

Dear RHESSI Collaborators,
Solar activity has been at very low levels over the past 24 hours.
NOAA 12322 was the source of a C1.0 event at 00:33 UT today.
The target region NOAA 12321 maintains its E-type/beta-gamma
configuration, but further decreases in spot area. It shows some
flux emergence in the leading and intermediate portions. Only
low-level activity expected in the next 24 hours.
The position of NOAA 12321 on April 20 at 11:35 UT is:
N11W43 (Solar X = 641", Solar Y = 244")

Dear RHESSI Collaborators,
Solar activity continues at low levels. The target region NOAA 12321
was the source of two low C-class events since the last message. 12321
retains its E-type/beta-gamma configuration, but has lost some of its spot
area and number of spots. The two small filaments are still hanging
above this region. 12321 continues to be the primary target today, with
a chance of additional low activity. NOAA 12324 (N19E01) and 12325
(N05E11) also have potential to produce some low-level activity over the
next 24 hours.
The position of NOAA 12321 on April 19 at 11:35 UT is:
N11W29 (Solar X = 456", Solar Y = 257")

Dear RHESSI Collaborators,
Solar activity has been at very low levels since the last message,
however, only an hour earlier today, there occurred a C5.2 X-ray event
due to a filament eruption from the target region NOAA 12321, which
was associated with a two-ribbon flare. There are still two small filaments
across the region. 12321 maintains its E-type/beta-gamma classification,
and keeps showing mixed polarities in both the leading and trailing portions.
It continues to be today's target region, with additional low activity likely
in the next 24 hours.
The position of NOAA 12321 on April 18 at 11:35 UT is:
N11W15 (Solar X = 243", Solar Y = 267")

Dear RHESSI Collaborators,
Solar activity is at intermediate-to-low levels, with a few low C-class
events from NOAA 12324 and 12325 since the last message. The
target region NOAA 12321 maintains its E-type/beta-gamma magnetic
configuration and continues to show mixed polarities in both the leading
and trailing portions. It is displaying bright H-alpha plage as well a
filament across the region, with the potential to produce low activity in
the next 24 hours.
The position of NOAA 12321 on April 17 at 11:35 UT is:
N12W05 (Solar X = 81", Solar Y = 287")

Dear RHESSI Collaborators,
There has been a minor resurgence in solar activity, with several
C-class flares since the last message, including a C7.8 from NOAA
12321 at 20:13 UT yesterday. The target region has begun to decay and
fragment but maintains its beta-gamma configuration. Further low-level
activity expected over the next 24 hours.
The position of NOAA 12321 on 16-Apr-2015 at 15:35 UT is:
N12E07, ( -114", 288" )

Dear RHESSI Collaborators,
Solar activity continues at low levels despite the presence of three
large active regions on the visible hemisphere. The target region NOAA
12321 has been downgraded to a beta-gamma region and has been
predominantly quiescent except for a C1.5 flare at 11:35 UT today.
Only minor events expected over the next 24 hours.
The position of NOAA 12321 on 15-Apr-2015 at 15:35 UT is:
N13E17, ( -273", 302" )
