Dear RHESSI Collaborators,
Solar activity remains at low levels. Yesterday's target region NOAA
12371 has rotated over the west limb. NOAA 12373 will be today's
target region. 12373 was the source of three low C-class events, the
largest being a C2.4 at 06/29/17:58 UT, over the past 24 hours. 12373
was classified as an F-type/beta configuration. It is showing mixed
polarities across the whole region. It is interesting that 12373 seems
to be interacting with the adjacent prominence/filament. C-class activity
is expected with a slight chance of an M-class event in the next 24-48
hour period.
The position of NOAA 12373 on June 30 at 11:35 UT is:
N15E48 (Solar X = -679", Solar Y = 215")

Dear RHESSI Collaborators,
Solar activity continues at low levels. At this time we are ending the
Major Flare Watch campaign, but remain on NOAA 12371 with some
high-lying loops for one more day. 12371 was the source of the largest
event, a C2.2 at 06/29/00:27 UT, since the last message. A new region,
designated as NOAA 12373 (N15E60), is rotating onto the visible disk.
It was the source of several C-class events today, and has a D-type/beta
magnetic configuration. It should be tomorrow's target region. C-class
activity is expected with a small chance of an M-class event in the next
24 hours.
The position of NOAA 12371 on June 29 at 11:35 UT is:
N13W91 (Solar X = 918", Solar Y = 212")

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA 12371 appears to have
decayed further as it rotated up to the North West limb, but some
of the decrease in spot area and number of spots is likely due to
foreshortening effects. 12371 decreased slightly in complexity in
the past 24 hours, being designated as a beta-gamma/E-type sunspot
group classification and was the source of the largest flare since
yesterday’s message, a C1.1 on 28-Jun-2015 at 06:07 UT. We are now
entering the final 24 hrs of the current MM#003 Major Flare Watch,
which will remain on NOAA 12371 until its high-lying loops rotate
completely out of view over the limb. C-class flares are expected
in the next 24 hrs, with a good chance for a final flare above the
M5 level.
The position of NOAA 12371 on 28-Jun-2015 at 21:00 UT is:
N12W90, ( 923”, 196” )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12371 has continued to
decay as it rotates towards the North West limb. This region has
remained classified as a beta-gamma/F-type sunspot group and was
the source of the largest flare since yesterday's message, a C1.4
on 27-Jun-2015 at 10:52 UT. The MM#003 Major Flare Watch remains
in effect on 12371 as this region still retains the potential for
flaring above the M5 level.
The position of NOAA 12371 on 27-Jun-2015 at 21:30 UT is:
N13W76, ( 892", 203" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 12371 continues to decay
and has produced three low C-class flares since yesterday's M7.9
flare. This region has remained classified as a beta-gamma/F-type
sunspot group and will continue as the MM#003 Major Flare Watch
target for at least another 24 hours. C-class flares are expected
in that period, with a good chance for further M-class flaring.
The position of NOAA 12371 on 26-Jun-2015 at 18:30 UT is:
N12W63, ( 825", 179" )

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:

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")
