Dear RHESSI Collaborators,
Solar activity continues to be at a very low level. Yesterday's
target region has been designated as NOAA 12570 and classified
as a beta/B-type sunspot group. There have been no flares since
the last message. Low-to-mid B-class flares are possible in the
following 24 hours.
The position of NOAA 12570 on 29-Jul-2016 at 22:00 UT is:
N11E54, ( -751", 126" )

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target region
has continued as an unnumbered plage field region and was the source
of the only flare since the last message (a B1.1 on 28-Jul-2016 at
13:44 UT). However, over the past 24 hours a new region with spots
has rotated over the North East limb and currently displays a beta
magnetic classification. B-class flares are possible over the next
24 hours.
The approximate position of this region on 28-Jul-2016 at 22:00 UT is:
N10E70, ( -874", 132" )

Dear RHESSI Collaborators,
Solar activity has continued at a low level. Yesterday’s target region
in the South East quadrant remained as an unnumbered plage field, but
some small pores may be developing in the negative polarity portion.
B-class flares are possible over the next 24 hours.
The approximate position of this region on 27-Jul-2016 at 21:00 UT is:
S17E45, ( -644", -337" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12567 has rotated completely
beyond the North West limb. A region of magnetic flux is located in
the South East quadrant, but is likely to be plage field as there do
not appear to be any spots associated with it. B-class flares are
likely over the following 24 hours.
The approximate position of this region on 26-Jul-2016 at 16:00 UT is:
S17E64, ( -816", -312" )

Dear RHESSI Collaborators,
Solar activity is returning to a low level. NOAA 12567 has rotated
up to the North West limb. This region was last reported as having
maintained a beta/D-type sunspot group classification, but this is
impossible to verify given its location at/over the limb. 12567 has
continued to produce activity since the last message, albeit at a
reduced magnitude and frequency, including the largest flare of the
period (a C1.8 on 25-Jul-2016 at 08:59 UT). More C-class flares are
possible over the next 24 hours, with a chance for an isolated low
M-class flare as the high-lying loops of NOAA 12567 rotate beyond
the limb.
The position of NOAA 12567 on 25-Jul-2016 at 11:00 UT is:
N05W90, ( 941", 82" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. The target region
NOAA 12567 produced two low M-class flares, M2.0
at 06:09 UT and M1.9 at 17:30 UT on July 24. 12567
was also the source of numerous C- and B-class events.
It is retaining its beta/D-type sunspot group as rotating
over the west limb. Occulted C-class flares are expected,
with a slight chance of low M-class activity over the
following 24 hours.
The position of NOAA 12567 on July 24 at 17:20 UT is:
N05W90 (940", 81")

Dear RHESSI Collaborators,
Solar activity was at a high level in the past 24 hours. The target
region NOAA 12567 (very close to NOAA 12565, N04W84) produced
three major flares, M5.0 at 01:46 UT, M7.6 at 05:00 UT, and M5.5
at 05:27 UT on July 23, with the largest one associated with a non-
Earth-directed CME. At this point, we are not implementing a Major
Flare Watch because NOAA 12567 seems to simplify its magnetic
complexity after producing those three major flares. 12567 has a
beta/D-type sunspot group now decreasing in sunspot area (330 uh,
i.e., less than 500 uh). It is rotating over the west limb, but still has
the potential to produce (low) M-class events in the next 24 hours.
The position of NOAA 12567 on July 23 at 14:20 UT is:
N06W75 (907", 76")

Dear RHESSI Collaborators,
Solar activity is at a low level. The largest event since the last
message was a C6.6 at 06:58 UT on July 22 produced by the
target region NOAA 12567. 12567 was also the source of a few
high B-class events. 12567 was re-classified as a beta-gamma/
D-type sunspot group but decreasing in spot area and number
of spots. It is rotating onto the west limb. Further C-class flares
are expected in the next 24 hour period.
The position of NOAA 12567 on July 22 at 17:20 UT is:
N05W62 (832", 43")

Dear RHESSI Collaborators,
Solar activity has increased since the last message. Two
low M-class flares (M1.2 at 00:42 UT and M1.0 at 01:34 UT
on July 21) were produced by the target region NOAA 12567.
12567 was also the source of a few C-class events, including
a C9.1 several hours ago. 12567 has a beta/D-type sunspot
group, increasing in spot area and number of spots. More C-
class events are expected, with a chance of low M-class
activities in the following 24 hours.
The position of NOAA 12567 on July 21 at 14:20 UT is:
N05W46 (678", 25")

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the
last message was a C4.2 flare at 03:08 UT on July 20 produced
by the target region NOAA 12567. NOAA 12567 and also 12565
(N06W47) were the sources of some other low C-class flares and
numerous high B-class events. These two regions are continuing
interacting with each other in the coronal loops and also filaments.
Please include both of them in your field of view if possible. 12567
has now been reclassified as a beta-gamma/D-type sunspot group.
Further low C-class events are expected with a chance of an isolated
high C-level flare in the next 24 hour period.
The position of NOAA 12567 on July 20 at 20:20 UT is:
N05W36 (554", 17")
