Dear RHESSI Collaborators,
The current level of solar activity is high. Since the
previous message, an X1.3 flare has occurred on
25-Apr-2014 at 00:17 UT at the limb, likely within
yesterday's target region (NOAA 12035), which is
located beyond the West limb. The flare was likely
connected to today's target region (newly numbered
NOAA 12046). Therefore, the target will remain with
NOAA 12046. If possible, the instrument should
include the area at the West limb, just to the North-
West of 12046 within its FOV. A Major Flare Watch
(MFW) is now in effect. A further significant flare
(>M5) is possible.
The position of 12046 on 25-Apr-2014 at 01:10 UT is:
S17W79, ( 895", -263" )

Dear RHESSI Collaborators,
The current level of solar activity is low. Since the
previous message, yesterday's target (NOAA 12035)
was responsible for C-class activity, but has now
rotated over the West limb. A new bipolar region has
emerged 10-20 degrees east of 12035. So far it has
been connected to at least one C-class event rooted
in 12035. Further low C-class activity is expected.
The position of the new region on 24-Apr-2014 at 17:20 UT is:
S17W73, ( 875", -256" )

Dear RHESSI Collaborators,
The current level of solar activity is low-moderate.
Since the previous message, yesterday's target
(NOAA 12035) was responsible for C-class activity,
including the largest since the previous message, a
C5.1 flare on 23-Apr-2014 at 12:48 UT. Flux
emergence within the region appears to have
subsided. Further moderate C-class activity is
possible, with a chance for a high C-class flare.
The position of NOAA 12035 on 23-Apr-2014 at 17:40 UT is:
S13W81, ( 918", -201" )

Dear RHESSI Collaborators,
The current level of solar activity is low-moderate. Since the
previous message, yesterday's target (NOAA 12035) was
responsible for a series of C-class events, including the
largest event since the previous message, a C8.8 flare on
22-Apr-2014 at 11:29 UT. The region is undergoing continued
flux emergence and exhibits at least one small mixed-polarity
spot. Further high C-class activity is possible, with a chance
for a low M-class flare.
The position of NOAA 12035 on 22-Apr-2014 at 17:20 UT is:
S15W68, ( 853", -216" )

Dear RHESSI Collaborators,
The current level of solar activity is low. Since the previous
message, yesterday's target (NOAA 12036) was responsible
for low C-class activity, but is now rotating over the west limb.
NOAA 12034, 12045, and 12038 have also produced minor
C-class events. On the other hand, new flux emergence
occurred in the North portion of NOAA 12035, that (in addition
to nearby NOAA 12036) may act to destabilise NOAA 12035.
Low C-class activity is expected with a chance for a moderate
C-class event.
The position of NOAA 12035 on 21-Apr-2014 at 17:45 UT is:
S16W53, ( 732", -214" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA regions 2034 (N05W59), 2035 (S16W38), and target
region 2036 (S17W61) are producing C-class activity.
2036 has formed a weak magnetic delta configuration in
the leader sunspot. C-class events probable with a slight
chance of an isolated M-class event in the next 24 hours.
The position of NOAA 2036 on April 20 at 11:30 UT is:
S17W61 (Solar X = 566", Solar Y = -197")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity has been at a low level for the past
24 hours. NOAA 2036 continues to decay following
the major M7.3 event yesterday but is maintaining
a beta-gamma magnetic configuration. NOAA 2035, S15W27,
is also magnetically complex displaying a beta-gamma
configuration. Both 2036 and 2035 are capable of
producing C-class events with a chance of an isolated
M-class event in the next 24 hours. A major flare event
is less likely in the next 24 hour period.
The position of NOAA 2036 on April 19 at 15:30 UT is:
S16W50 (Solar X = 705", Solar Y = -208")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region NOAA 2036 was the source of a major
two-ribbon proton flare with an associated CME. The
x-ray event peaked at M7.3 at 04/18/13:03 UT. 2036
has decayed following the event but is still maintaining
its beta-gamma magnetic configuration. At this time we are
implementing Max Millennium coordinated observing plan
#003 (Region Likely To Produce A Major Flare).
There is a chance that 2036 might produce another
event =/>M5 in the next 24-48 hours.
The position of NOAA 2036 on April 18 at 11:30 UT is:
S15W35 (Solar X = 531", Solar Y = -176")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The largest event in the past 24 hours was an isolated
M1.0 at 04/16/19:59 UT produced by NOAA 2035, S17E04.
Target region(s) NOAA 2036 and 2037 were the source
of C-class activity. Primary target 2036 has decayed slightly
but appears to be the most magnetically interesting of the
3 beta-gamma regions and will continue to be the target.
If possible, include 2037 within the F-O-V. C-class events
probable with the chance of an M-class event in the next
24 hours.
The position of NOAA 2036 on April 17 at 11:30 UT is:
S18W21 (Solar X = 326", Solar Y = -214")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
There are currently three regions near disk center with
beta-gamma magnetic configurations producing C-class
events. The regions are target region NOAA 2036 and
2037 (S09W06) and 2035 (S19E17). If possible, include
2037 within the F-O-V. C-class events expected with the
possibility of an isolated M-class event in the next 24 hours.
The position of NOAA 2036 on April 16 at 15:30 UT is:
S18W10 (Solar X = 158", Solar Y = -209")
