MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2403 continues to decay especially within its trailing
portion. 2403 is currently classified as an F-type/beta-gamma
sunspot with a weak magnetic delta configuration located in
its leading polarity sunspot. 2403 was the source of numerous
C-class events and an isolated M2.2 event at 08/28/13:16 UT.
C-class events expected with the chance of another M-class
event in the next 24 hour period. A major flare =/>M5 is now
not likely.
The position of NOAA2403 on August 28 at 12:30 UT is:
S15W64 (Solar X = 825", Solar Y = -294")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2403 continues to slowly decay but is still displaying
a somewhat complex F-type/beta-gamma-delta sunspot
group. 2403 was the source of an isolated M2.9 event
at 08/27/05:44 UT. Another isolated M-class event is
possible with a slight chance of an M-class event =/>M5
in the next 24 hour period.
The position of NOAA 2403 on August 27 at 14:35 UT is:
S16W53 (Solar X = 730", Solar Y = -328")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2403 continues to slowly decay but is maintaining
its F-type/beta-gamma-delta classification. There are small
opposite polarity flux elements located within both the large
leading and following spot penumbrae. 2403 was only able
to produce numerous C- and B-class events since the last
message. The largest was a C9.5 at 08/26/13:53 UT.
Although 2403 is currently losing its magnetic complexity
somewhat, we will continue the MM#003 observing plan for
another 24 hours. There is still a slight chance of an event
=/>M5.
The position of NOAA 2304 on August 26 at 12:30 UT is:

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2403 is maintaining its large F-type/beta-gamma-delta
sunspot group. There are small magnetic delta configurations
located within the leading and trailing sunspots. 2304 was the
source of an isolated M1.0 event at 08/24/17:46 UT. 2403
also produced countless C- and B-class events since the last
message. C- and M-class events expected with the chance
of an event =/>M5 in the next 24 hour period.
The position of NOAA 2403 on August 25 at 14:35 UT is:
S15W27 (Solar X = 417", Solar Y = -345")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 2403, was the source of an impulsive
M5.6 event at 08/24/07:33 UT. 2403 also produced 13
C-class events since the last message. 2403 has decayed
slightly following the M5 event but is still a large F-type
sunspot group with a beta-gamma-delta magnetic configuration
with the potential to produce another event =/>M5.
At this time we are implementing Max Millennium coordinated
observing plan #003. C-class events certain with a
chance for a major flare =/>M5 in the next 24 hour period.
The position of NOAA 2403 on August 24 at 14:35 UT is:
S15W13 (Solar X = 206", Solar Y = -354")

Dear RHESSI Collaborators,
Solar activity remains at a moderate level. The largest event in the
past 24 hours was an M3.5 at 08/22/21:19 UT produced by the target
region NOAA 12403. 12403 was also the source of 8 C-class flares.
12403 is now classified as a beta-gamma-delta/E-type sunspot group,
with increasing in sunspot area and number of spots slightly. It still has
the potential to produce an isolated low M-class activity in the next 24
hours.
The position of NOAA 12403 on August 23 at 14:35 UT is:
S14W00 (Solar X = 0”, Solar Y = -340")

Dear RHESSI Collaborators,
Solar flare activity continues at moderate levels. Three low M-class
flares (M1.1 at 08/21/19:10 UT, M1.2 at 08/22/06:39 UT, and M2.2
at 08/22/13:17 UT) were produced by the target region NOAA 12403
in the previous 24 hours. 12403 was also the source of several high
level C-class events. 12403 continues to increase in sunspot area
and number of spots, and remains classified as a beta-gamma/D-type
sunspot group. It is continuing to mix polarities in its intermediate portion.
Seems that the magnetic field in its leading portion becomes stronger.
C-class flares are expected, with a potential of (high) M-class activity.
The position of NOAA 12403 on August 22 at 14:35 UT is:
S14E14 (Solar X = -223", Solar Y = -336")

Dear RHESSI Collaborators,
Solar flare activity has been at a moderate level. The target region
NOAA 12403 was the source of two low M-class events (an M1.2 at
2015/08/21/01:56 UT and an M1.4 at 2015/08/21/09:34 UT) and a
few C- and B-class flares in the past 24 hours. 12403 has increased
its sunspot area and number of spots significantly, and is now designated
as a beta-gamma/D-type configuration. It continues to show mixed
polarities in its intermediate portion. Further C-class flares are expected
with a chance of additional low M-class activity.
The position of NOAA 12403 on August 21 at 14:35 UT is:
S13E28 (Solar X = -435", Solar Y = -310")

Dear RHESSI Collaborators,
Solar flare activity has increased today. Target region NOAA 12403 has
produced three C-class events (the largest being a C3.4 at 08/20/05:08 UT
associated with a small filament eruption) and numerous B-class events
since the last message. 12403 is now classified as a beta/D-type sunspot
group, increasing in sunspot area and number of spots (also total unsigned
current helicity). It is showing some mixed polarities in its
intermediate portion.
Additional C-class flares are expected with a chance of a low M-class event
in the next 24 hour period.
The position of NOAA 12403 on August 20 at 14:35 UT is:
S12E41 (Solar X = -610", Solar Y = -280")

Dear RHESSI Collaborators,
Solar activity continues to be very low. NOAA region 12401 appeared
to slow in its decay over the past 24 hours and remains classified as
a beta/C-type sunspot group. A new region rotated over the South East
limb yesterday and has been designated as NOAA 12403. This region is
also classified as a beta/C-type sunspot group, but may have polarity
mixing in its interior obscured by still being too close to the limb.
12403 produced B-class activity since the last message, including the
largest flare of the period (a B6.8 on 19-Aug-2015 at 10:48 UT). More
B-class flaring is expected over the next 24 hours, with a chance for
some C-class activity.
The position of NOAA 12403 on 19-Aug-2015 at 13:00 UT is:
S12E57, ( -778", -256" )
