Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target
(NOAA 12089) was responsible for low C-class activity
since the previous message. The region has decayed
significantly and is not progressing over the limb. The
largest event over the last 24 hours, a C4.0 flare on
18-Jun-2014 at 03:31 UT, was released by NOAA 12087.
Flux emergence within the region appears to have
largely subsided, but the region is magnetically classed
as a beta-gamma. Further low C-class activity is
expected with a chance for a high C-class flare.
The position of NOAA 12087 on 18-June-2014 18:40 UT is:
S19W32, ( 477", -327" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target
(NOAA 12089) was responsible for low C-class activity.
The largest event over the last 24 hours, a C4.7 flare on
17-Jun-2014 at 05:10 UT, was released by NOAA 12087.
While this region has emerged new flux, its magnetic
configuration remains simple. NOAA 12089 still shows
evidence for a gamma configuration and a strong polarity
separation line. Further C-class activity is expected, with
a chance for a high C-class flare.
The position of NOAA 12089 on 17-June-2014 19:45 UT is:
N18W63, ( 800", 283" )

Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. Yesterday's
target, the (still) un-numbered region at the South-East
limb was responsible for moderate C-class activity. On
the other hand, two low M-class and two high C-class
flares originated behind the SW limb (likely from NOAA
12085 and 12084). The flare site has now rotated far
enough behind the E-limb that further significant flares
from the region are not expected. The most complex
region on disk is NOAA 12089 (showing a beta-gamma-
delta magnetic classification), and has released a series
of low C-class flares over the previous 12 hours.
Continuing flux emergence is evident, as well as some
shearing, as negative polarity flux flows into the following
positive polarity spots, forming a double polarity separation
line. Moderate C-class activity is expected, with a chance
for a low M-class flare.
The position of NOAA 12089 on 16-June-2014 17:40 UT is:
N18W48, ( 666", 280" )

Dear RHESSI Collaborators,
The level of solar activity is low-to-moderate. NOAA 12087 has
decreased in flare productivity over the past 24 hours, while
NOAA 12085 produced C-class flares and an M1.1 on 15-Jun-2014
at 11:10 UT. However, 12085 is currently rotating out of view
over the South West limb. A new (currently unnumbered) region
at the South East limb produced an M1.4 flare on 14-Jun-2014
at 19:23 UT and becomes the new target region. C-class flares
are expected in the next 24 hours, with a chance for another
low M-class event.
The approximate position of this region on 15-Jun-2014 at 14:00 UT is:
S10E90, ( -930", -164" )

Dear RHESSI Collaborators,
Solar activity is at a low-to-moderate level. NOAA 12087 has
continued to be the most flare productive region on disk and
was the source of the largest event in the past 24 hours (a
C9.0 flare on 13-Jun-2014 at 20:13 UT). NOAA 12087 remained
classified as a beta-gamma-delta region but was reclassified
as an E-type sunspot group. Note that the delta spot in NOAA
12087 has disappeared since classifications were issued. At
this time we are ceasing the MM#003 Major Flare Watch, due
to the reduced frequency and magnitude of flaring from NOAA
12087 and its reduced magnetic complexity. Further C-class
activity is expected in the following 24 hours, with a good
chance for more low M-class events.
The position of NOAA 12087 on 14-Jun-2014 at 12:30 UT is:
S18E23, ( -355", -306" )

Dear RHESSI Collaborators,
The level of solar activity remains high. Three active regions
(NOAA 12085, 12087, 12089) have produced low M-class flares in
the past 24 hours. 12087 is the most flare productive (having
been the source of 2 C-class flares and 3 M-class flares) and
it has been reclassified as a beta-gamma-delta/D-type sunspot
group. The MM#003 Major Flare Watch will continue for the next
24-48 hours, as NOAA 12087 maintains the potential for further
flaring above the M5 level.
The position of NOAA 12087 on 13-Jun-2014 at 14:00 UT is:
S18E35, ( -521", -303" )

Dear RHESSI Collaborators,
Solar activity continues to be at high levels. NOAA 12087 has
remained the most flare productive region on the visible disk.
This region has now been reclassified as a beta-gamma/D-type
sunspot group after rotating away from the limb. NOAA 12087
was the source of 5 C-class flares and 3 M-class flares since
yesterday's message (an M3.9 flare on 11-Jun-2014 at 20:53 UT,
an M2.0 flare on 12-Jun-2014 at 04:14 UT and an M2.7 flare on
12-Jun-2014 at 10:14 UT). The MM#003 Major Flare Watch will
continue for at least the next 24-48 hours, as NOAA 12087 has
the potential for further flaring above the M5 level.
The position of NOAA 12087 on 12-Jun-2014 at 11:00 UT is:

Dear RHESSI Collaborators,
The level of solar activity remains high. The region previously
numbered NOAA 12065 has fully rotated over the South East limb
and is now designated as 12087. This region is classified as a
beta-delta/D-type sunspot group and has continued to be flare
productive since yesterday's email, being the source of several
C-class flares, an M3.0 flare (on 11-Jun-2014 at 08:00 UT) and
an X1.0 flare (on 11-Jun-2014 at 08:59 UT). The MM#003 Major
Flare Watch will remain in effect for the next 24-48 hours, as
this region has the potential for further flaring above the M5
level.
The position of NOAA 12087 on 11-Jun-2014 at 13:00 UT is:
S18E64, ( -808", -296" )

Dear RHESSI Collaborators,
Solar activity is at a high level. The region previously numbered
NOAA 12065 is currently rotating over the South East limb and has
produced two low X-class flares in the last two hours (an X2.2 on
10-Jun-2014 at 11:36 UT and an X1.5 on 10-Jun-2014 at 12:36 UT).
Although this active region is too close to the limb to determine
an accurate magnetic complexity, its flare productivity means that
at this time we are commencing a MM#003 Major Flare Watch. C-class
activity is expected in the next 24 hours, with a good chance for
further flaring above the M5 level.
The approximate position of this region on 10-Jun-2014 at 13:00 UT is:
S19E89, ( -893", -308" )

Dear RHESSI Collaborators,
The level of solar activity continues to be low. NOAA 12080 has
grown in spot area but reduced in number of spots over the past
24 hours. This region is still classified as a beta-gamma-delta/
D-type sunspot group, but the delta spot appears to be weakening
with the main trailing negative polarity spot beginning to lose
its penumbra. NOAA 12085 has continued to grow in both spot area
and number of spots with emerging new magnetic flux over the past
24 hours. 12085 remains classified as a beta-gamma/E-type sunspot
group and was the source of two C-class flares since yesterday's
message, the largest being a C3.7 on 9-Jun-2014 at 01:14 UT. The
trailing spots of 12085 have started merging and are forming more
mature penumbrae. Additional C-class activity is expected in the
next 24 hours, with a chance for an isolated low M-class flare.
The position of NOAA 12085 on 9-Jun-2014 at 12:00 UT is:
S20W10, ( 148", -330" )
