Dear RHESSI Collaborators,
The level of solar activity is moderate-to-high. NOAA 12371
continues to decay with decreasing in spot area, number of
spots, and is now designated as a beta-gamma/F-type sunspot
group. 12371 was the source of an M7.9 flare on 25-Jun-2015
at 08:02 UT. The MM#003 Major Flare Watch will continue for
another 24-48 hours. C-class activity is expected, with a
good chance for further M-class flares.
The position of NOAA 12371 on 25-Jun-2015 at 16:30 UT is:
N11W49, ( 702”, 157” )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 12371 has shown some further
signs of decay, but has only decreased marginally in area with no change
in number of spots. This region was designated as a beta-gamma-delta/F-type
sunspot group, but may have now lost its delta configuration. 12371 was the
source of the largest flare since the the last email (a C5.6 on 24-Jun-2015
at 15:12 UT). Further C-class activity is expected over the next 24 hours,
with a chance for another flare above the M5 level.
The position of NOAA 12371 on 24-Jun-2015 at 18:30 UT is:
N12W38, ( 573”, 170” )

Dear RHESSI Collaborators,
Solar activity is at a moderate-to-high level. NOAA region 12371 has
shown some initial signs of decay over the past 24 hours, decreasing
slightly in spot area and reasonably in number of spots. This region
has remained classified as a beta-gamma-delta/F-type sunspot group,
and was the source of two low C-class events since yesterday's M6.5
flare. The MM#003 Major Flare Watch will continue for a further 24
to 48 hours as this region still shows signs of significant magnetic
shear and possible spot rotation. More C-class activity is expected
over the next 24 hours, with a good chance for M-class flares and a
small chance of an isolated X-class flare.
The position of NOAA 12371 on 23-Jun-2015 at 16:00 UT is:
N13W22, ( 343", 183" )

Dear RHESSI Collaborators,
The level of solar activity is high. NOAA region 12371 continues to be the
largest region on disk and has increased in number of spots over the past
24 hours, with a marginal increase in spot area. This region is classified
as a beta-gamma-delta/F-type sunspot group and produced an M6.5 flare on
22-Jun-2015 at 17:39 UT. Further M-class flares are possible over the next
24 hours, with a chance for a low X-class event.
The position of NOAA 12371 on 22-Jun-2015 at 21:30 UT is:
N13W12, ( 190”, 183” )

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
The largest x-ray event in the past 24 hours was an impulsive
M3.8 at 06/21/09:44 UT produced by NOAA 2367, S17W57.
Target region NOAA 2371 was the source of an interesting
twin M-class and large flare event. (M2.0 at 06/21/01:42
followed by an M2.7 at 06/21/02:34). The twin event was
associated with a full-halo CME. 2371 is maintaining its
E-type/beta-gamma-delta sunspot group. An isolated event
=/>M5 is possible in the next 24 hour period.
The position of NOAA 2371 on June 21 at 11:00 UT is:
N13E10 (Solar X = -160", Solar Y = 186")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 2371 was the source of C-class activity and an isolated
M1.0 event at 06/20/06:47 UT. 2371 is maintaining its large
E-type/beta-gamma-delta sunspot group. The delta, although large,
has a somewhat weak magnetic configuration due to its
widely-spaced opposite polarity umbrae. We will continue
the major flare watch for another 24 hours. An isolated
M-class event =/>M5 is still possible.
The position of NOAA 2371 on June 20 at 11:00 UT is:
N13E23 (Solar X = -361", Solar Y = 189")

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Target region, NOAA 2371, was the source of C-class events
and a long-duration M3.0 event at 06/18/17:36 UT. The largest
C-class event was a C8.1 at 06/19/09:27 UT. NOAA's region
classification is E-type/beta-gamma-delta (BGD). At this time
we are implementing coordinated observing plan #003
(Region Likely To Produce A Major Flare =/> M5).
The position of NOAA 2371 on June 19 at 11:00 UT is:
N13E36 (Solar X = -543", Solar Y = 194")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The largest x-ray event in the past 24 hours was an isolated
M1.2 at 06/18/01:27 UT. The location was near NOAA 2365
(S13W91). Target region NOAA 2371 has increased in
sunspot count, sunspot area and magnetic complexity.
2371 is currently a large E-type/beta-gamma region. C-class
events expected with an increase in the possibility of an
isolated M-class event in the next 24 hour period.
The position of NOAA 2371 on June 18 at 11:00 UT is:
N13E50 (Solar X = -707", Solar Y = 199")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region (now numbered NOAA 2371) is mostly
unchanged displaying bright dynamic H-alpha plage.
2371 currently appears to have a D-type/beta sunspot group.
2371 was the source of a few C-class events since the
last message. The largest was a C3.2 at 06/16/00:01 UT.
C-class events expected with an isolated M-class event
possible in the next 24 hour period.
The position of NOAA 2371 on June 17 at 15:00 UT is:
N13E63 (Solar X = -822", Solar Y = 204")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The northeastern target region was the source of a
C2.7 event at 06/16/0406 UT. The target region continues
to display bright and dynamic H-alpha plage east of the large
leader sunspot. The region is currently too close to the limb
to ascertain its magnetic configuration. C-class events
probable with an isolated M-class event possible in the
next 24 hour period.
The position of the target on June 16 at 11:00 UT is:
N13E80 Solar X = -907", Solar Y = 209")
