Dear RHESSI Collaborators,
Solar activity is at very low levels. There was a QS-filament/prominence
eruption at ~07/04/19:30 UT near the northeast limb, which was associated
with a limb CME. Yesterday's target region NOAA 12378 has only produced
a B6.4 flare since the last message. It has been downgraded to a C-type
region. A newly designated region, NOAA 12381, has a beta/C-type magnetic
configuration. It was the source of a B7 and a C1 events today. 12381 is
undergoing flux emergence in its leading portion. it will be today's target
region, with the potential to produce some C-class activities.
The position of NOAA 12381 on July 5 at 11:35 UT is:
N16E50 (Solar X = -696", Solar Y = 226")

Dear RHESSI Collaborators,
Solar activity has been at very low levels since the M1.5 flare. The
target region NOAA 12378 was the source of two C1 events. 12378
was classified as a Beta/D-type sunspot group. It is showing some
mixed polarities in its intermediate portion. C-class activity is likely
in the next 24 hours.
The position of NOAA 12378 on July 4 at 11:35 UT is:
S17E49 (Solar X = -682", Solar Y = -309")

Dear RHESSI Collaborators,
Solar flare activity has increased significantly today. The largest event
over the past 24 hours was an M1.5 at 07/03/12:47 UT produced by a
newly designated region, NOAA 12378. 12378 was also the source of
a few C-class events, including a C5.6 at 07/03/02:54 UT. Yesterday's
target region NOAA 12376 has shown some signs of decay, and only
produced a C1.2 since the last message. Today the target will switch to
NOAA 12378. Although 12378 was classified as a beta/C-type sunspot
group (maybe too close to the east limb to ascertain its exact configuration),
it has the potential to produce further C-class activity as well as another
low M-class event.
The position of NOAA 12378 on July 3 at 11:35 UT is:
S15E57 (Solar X = -765", Solar Y = -271")

Dear RHESSI Collaborators,
Solar activity remains at low levels with several low C-class events
emanating from various regions. The largest event is a C3.7 that is
just over. This flare comes from the target region NOAA 12376. 12376
remains its beta-gamma/E-type configuration, but increases in sunspot
area and number of spots. It is showing some mixed polarities in both
the leading and trailing portions. C-class activity is expected with a slight
chance of a low M-class event over the next 24 hours.
The position of NOAA 12376 on July 2 at 15:35 UT is:
N13E37 (Solar X = -555", Solar Y = 174")

Dear RHESSI Collaborators,
The level of solar activity has been very low. Yesterday's target contains
two active regions, with the east one newly designated as NOAA 12376.
12376 was the source of a C1.0 at 06/30/21:48 UT and a B8.8 at 07/01/
05:40 UT since the last message. 12376 has a complex beta-gamma/
E-type sunspot group and shows some evident positive flux emergence
in its intermediate portion. C-class activity is expected with a chance of
a low M-class event in the next 24-48 hours.
The position of NOAA 12376 on July 1 at 11:35 UT is:
N13E50 (Solar X = -706", Solar Y = 182")

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" )
