Dear RHESSI Collaborators,
Solar activity has diminished since the last message, with only minor
C-level events emanating from NOAA 12320, 12321, and 12322. The target
region NOAA 12321 retains its beta-gamma-delta configuration but may
be showing signs of decay in its core. Potential still exists for
further intermediate level events over the next 24 hours.
The position of NOAA 12321 on 14-Apr-2015 at 13:00 UT is:
N13E32, ( -495", 293" )

Dear RHESSI Collaborators,
Solar activity remains at intermediate levels with many C-class flares
over the past 24 hours, the largest being a C9.0 at 17:58 UT yesterday
from the target region, NOAA 12321. The region is now classified as a
beta-gamma-delta and is undergoing further development, particularly
in its core. There is another large sunspot group on the limb to the
east of the target region, which should be included in your
field-of-view if possible. Additional C-level activity likely with
chance of an M-class flare.
The position of NOAA 12321 on 13-Apr-2015 at 15:35 UT is:
N13E45, ( -660", 280" )

Dear RHESSI Collaborators,
The new target region near the northeast limb has now been designated
as NOAA 12321 and has produced several C-class flares since the last
message, as well as a long-duration M1.1 at 08:51 UT today. It is
classified as having a beta-gamma configuration and appears to be
undergoing further flux emergence within the dominant leader spot.
Further C- and M-level activity expected.
The position of NOAA 12321 on 12-Apr-2015 at 11:35 UT is:
N12E61, ( -820", 244" )

Dear RHESSI Collaborators,
Solar activity continues at intermediate levels with several C-class
flares emanating from NOAA 12320 over the past 24 hours. A large
sunspot group has appeared on the northeast limb but has only produced
a C4.7 flare (at 02:29 UT today) so far. The region is as yet
unnumbered and its magnetic configuration is unclear but it shall be
the new target region. The region has the potential to increase
activity significantly over the coming days.
The approximate position of the target region on 11-Apr-2015 at 15:35 UT is:
N13E74, ( -896", 241" )

Dear RHESSI Collaborators,
Solar activity has increased since the last message with several
C-class flares emanating from NOAA 12320. The largest was a C7.9 at
07:57 UT today. The positive leading spot has all but disappeared but
the trailing portion still contains a delta. Minor flux emergence may
lead to additional intermediate level events over the next 24 hours.
The position of NOAA 12320 on 10-Apr-2015 at 11:35 UT is:
S12W32, ( 498", -115" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 12320 was the source of a
C5.4 at 06:25 UT today. The region remains fairly stable and maintains
its beta-delta configuration, but may be showing signs of decay.
Possibility of isolated low-to-mid level events.
The position of NOAA 12320 on 9-Apr-2015 at 15:36 UT is:
S12W22, ( 352", -107" )

Dear RHESSI Collaborators,
Overall activity has decreased since the last message, although the
target region NOAA 12320 produced an M1.4 flare at 14:37 UT today. The
region continues to develop and is now classified as a beta-delta
region due to mixed polarity flux within its trailing portion. Chance
for another isolated intermediate level event in the next 24 hours.
The position of NOAA 12320 on 8-Apr-2015 at 11:35 UT is:
S12W05, ( 82", -98" )

Dear RHESSI Collaborators,
Solar activity continues at low levels with the target region NOAA
12320 producing another isolated C3 flare since the last message. The
region is now classified as having a beta-gamma configuration with
some positive polarity flux emerging into the negative-polarity
trailing sunspot. Additional C-level activity expected over the next
24 hours.
The position of NOAA 12320 on 7-Apr-2015 at 11:35 UT is:

Dear RHESSI Collaborators,
Solar activity continues at low levels. The target region NOAA 12320
only produced an isolated C3.0 flare since the last message. The
region continues to show signs of growth but retains its simple beta
configuration. Chance of additional isolated C-level events over the
next 24 hours.
The position of NOAA 12320 on 6-Apr-2015 at 11:35 UT is:
S12E21, ( -337", -103" )

Dear RHESSI Collaborators,
Solar activity has increased today. The largest event was a long duration
C3.8 at 22:16 UT on April 4 at S30E21, which was associated with a large
filament eruption, a two-ribbon flare, and a CME. There was another
C1.0 event at 19:20 UT produced by the newly numbered region NOAA
12320. NOAA 12320 was classified as a D-type/beta configuration. It is
showing flux emergence and also mixed polarities in the negative spot.
12320 will be the target region today. C-class activity is possible over the
next 24 hour period.
The position of NOAA 12320 on April 5 at 11:35 UT is:
S12E33 (Solar X = -512", Solar Y = -112")
