Dear RHESSI Collaborators,
Current solar activity is low-moderate. Since the
previous message, yesterday's target (NOAA 12056)
was responsible for a C6.8 flare on 13-May-2014 at
22:24 UT, but the region has now ceased emerging
flux. However, a new region has rapidly emerged near
N10E50 and was responsible for the largest event
since the previous message, a C8.3 flare on
14-May-2014 at 15:04 UT. There is some evidence
for a small amount of mixed polarity flux in the leading
spot. Further C-class activity is expected with a
chance for a low M-class flare.
The position of the new region on 14-May-2014 18:30 UT is:
N10E46, ( -671", 196" )

Dear RHESSI Collaborators,
Current solar activity is low. Since the previous message,
yesterday's target (NOAA 12056) was reponsible for low
C-class activity. The region has emerged a small bipole
in its intermediate portion, which may further destablilise
the region. Further C-class activity is expected, with a
chance for a high C-class flare.
The position of NOAA 12056 on 13-May-2014 18:20 UT is:
N05W19, ( 312", 127" )

Dear RHESSI Collaborators,
Current solar activity is low. NOAA region 12056 has
continued to decay, although it was responsible for
several C-class events, including the largest since
the previous message, a C3.4 flare on 11-May-2014 at
19:14 UT. While NOAA 12058 has rapidly emerged flux
over the previous 24 hours, it does not exhibit a strong
polarity separation line (PSL) and has not yet been
responsible for significant activity. Further C-class
activity is expected, with a chance for a high C-class
flare.
The position of NOAA 12056 on 12-May-2014 22:15 UT is:
N05W09, ( 154", 131" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 12056 has started
to show signs of decay (decreasing in both spot area and number
of spots over the past 24 hours), while remaining classified as
a beta-gamma/E-type sunspot group. This region has continued to
produce C-class activity since the last message with NOAA 12059
(an negative polarity alpha/H-type sunspot group) also emerging
beside the positive trailing spots of NOAA 12056. More C-class
flares are expected over the next 24 hours, with a chance for a
low M-class flare.
The position of NOAA 12056 on 11-May-2014 at 17:30 UT is:
N05E06, ( -104", 133" )

Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. NOAA region 12056
has increased slightly in spot area and number of spots over the
past 24 hours, but has been reclassified as a beta-gamma/E-type
sunspot group. This region produced the largest flare event since
the last message, a C8.7 on 10-May-2014 at 06:51 UT. At this time
we are ending the MM#003 Major Flare Watch as 12056 has slowed in
flux emergence and it has been confirmed no delta exists. Further
C-class flares are expected over the next 24 hours, with a chance
for a low M-class flare.
The position of NOAA 12056 on 10-May-2014 at 11:00 UT is:
N04E25, ( -400", 115" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. Yesterday's target NOAA region
12056 has increased in spot area and number of spots over the past 24
hours and is classed by NOAA/SWPC as a beta-gamma-delta/E-type sunspot
group. However, the reported trailing spot delta appears to be a false
limb-ward polarity reversal in the line-of-sight magnetic field. This
region has produced a C1.4 flare and several H-alpha flares since the
M5.2 flare on 8-May-2014 at 09:59 UT (note the revised start time by
NOAA/SWPC). The MM#003 Major Flare Watch will continue for the next 24
hours as NOAA 12056 has continued to show evidence of minor magnetic
flux emergence. More C-class activity is expected in the next 24 hours,
with a chance for another flare above the M5 level.
The position of NOAA 12056 on 9-May-2014 at 12:00 UT is:
N04E37, ( -577", 110" )

Dear RHESSI Collaborators,
The level of solar activity is moderate-to-high. Yesterday's target
NOAA 12051 has rotated fully beyond the South West limb. NOAA 12056
is now the most complex region on the visible disk and is classified
as a beta-gamma/D-type sunspot group. This region produced multiple
C-class flares over the past 24 hours and an M5.2 flare on 8-May-2014
at 09:20 UT. At this time we are starting a MM#003 Major Flare Watch,
as NOAA 12056 has shown signs of magnetic flux emergence over the past
24 hours. More C-class activity is expected, with a chance for another
flare above the M5 level.
The position of NOAA 12056 on 8-May-2014 at 12:00 UT is:
N04E49, ( -721", 103" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. NOAA 12051 produced a
second M-class event after yesterday's message - an M1.0 flare
on 6-May-2014 at 22:01 UT. This region was still classified as
a beta-gamma-delta/D-type sunspot group when rotating over the
South West limb. Further C-class activity is expected, with a
chance of additional low M-class activity before 12051 rotates
completely beyond the limb.
The position of NOAA 12051 on 7-May-2014 at 10:30 UT is:
S09W90, ( 939", -148" )

Dear RHESSI Collaborators,
Solar activity is elevated. Further C-level events have emanated from
NOAA 12047, NOAA 12051, and an as-yet unnumbered region over the
eastern limb. NOAA 12047 was also the source of an M1.8 flare at 08:41
UT today. NOAA 12051 shall remain the target region for a further 24
hours as it approaches the western limb. Chance for additional C-class
flares as well as a possible low M event before west limb transit.
The position of NOAA 12051 on 6-May-2014 at 17:00 UT is:
S09W88, ( 938", -146" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. Yesterday's target region
NOAA 12051 has continued to produce C-class activity, the largest
of which was a C9.2 flare on 4-May-2014 at 12:22 UT. This region
is still classified as a beta-gamma-delta/D-type sunspot group as
it rotates towards the South West limb. More C-class activity is
likely, with a slight chance for an isolated low M-class flare.
The position of NOAA 12051 on 5-May-2014 at 08:30 UT is:
S09W69, ( 877", -126" )
