Dear RHESSI Collaborators,
The level of solar activity is very low. Solar background soft X-ray
flux has gradually increased over the last 48 hours from mid-A-class
to low-B-class. This is due to the X-class producing region that was
previously designated as NOAA 12673 rotating up to the East limb from
the far side. C-class activity is possible in the next 24 hours, with
a small chance for M-class if old NOAA region 12673 has retained its
magnetic complexity.
The approximate position of this region on 23-Sep-2017 at 18:30 UT is:
S09E90, ( -944", -148" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA 12680 has rotated up to
the North West limb, while NOAA 12681 is clearly visible on the disk.
12681 has remained stable in terms of spot area and number of spots,
again being classified as an alpha/H-type sunspot group. No flares
have occurred in the past 24 hours. Low B-class flares are possible
in the following 24-hour period.
The position of NOAA 12681 on 22-Sep-2017 at 13:30 UT is:
S13E53, ( -745", -282" )

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target region
has been designated as NOAA 12681 and classified as an alpha/H-type
sunspot group. This region decreased in flare productivity, but was
the source of a B1.0 flare on 20-Sep-2017 at 20:00 UT. More B-class
activity is possible over the next 24 hours.
The position of NOAA 12681 on 21-Sep-2017 at 13:30 UT is:
S12E65, ( -848", -246" )

Dear RHESSI Collaborators,
Solar activity is very low. A new spotted region has rotated over the
South East limb in the past 24 hours, likely to be the return of NOAA
regions 12675/12676. This region has produced several B-class flares
since the last message, but remains too close to the limb to confirm
its magnetic classification. Further B-class activity is expected in
the following 24-hour period.
The approximate position of this region on 20-Sep-2017 at 20:00 UT is:
S14E78, ( -906", -254" )

Dear RHESSI Collaborators,
The level of solar activity is extremely low. NOAA 12680 remains
the only spotted region on disk and has decayed marginally over
the past 24 hours, decreasing slightly in spot area. This region
is again designated an alpha/H-type sunspot group classification.
No flares have occurred since the last message. An isolated low
B-class flare may be possible in the next 24 hours.
The position of NOAA 12680 on 19-Sep-2017 at 14:30 UT is:
N08W48, ( 705", 54" )

Dear RHESSI Collaborators,
Solar activity remains at an extremely low level. NOAA 12680 has
again maintained number of spots and area over the past 24 hours,
continuing to be classified as an alpha/H-type sunspot group. No
flares have occurred since the last message. Low B-class flares
may be possible over the following 24-hour period.
The position of NOAA 12680 on 18-Sep-2017 at 21:30 UT is:

Dear RHESSI Collaborators,
The level of solar activity continues to be extremely low. The target
region remains the only spotted region on disk. NOAA 12680 has slowed
in its decay phase, maintaining number of spots and area. This region
continues to be classified as an alpha/H-type sunspot group, while no
flares have occurred since the last message. Low B-class flares could
be possible in the next 24 hours.
The position of NOAA 12680 on 17-Sep-2017 at 21:30 UT is:

Dear RHESSI Collaborators,
Solar activity is at an extremely low level. NOAA 12680 remains the
only spotted region on disk. This region showed signs of decay with
increasing in number of spots while decreasing in spot area. 12680
has continued to be classified as an alpha/H-type sunspot group and
no flares have occurred since the last message. Low B-class flares
may be possible in the following 24-hour period.

Dear RHESSI Collaborators,
The level of solar activity is extremely low. A-class background
soft X-ray flux continues, with NOAA 12680 remaining the target.
12680 was again classified as an alpha/H-type sunspot group with
no change in sunspot area over the past 24 hours. No flares have
occurred since the last message. B-class activity may be possible
over the next 24 hours.
The position of NOAA 12680 on 15-Sep-2017 at 13:30 UT is:
N08E05, ( -82", 13" )

Dear RHESSI Collaborators,
Solar activity is at very low levels. The background soft X-ray
flux has remained in the A-class range over the past 24 hours.
The target will continue to be the only spotted region on disk,
NOAA 12680. This region maintained spot area and classification
as an alpha/H-type sunspot group since yesterday's message. No
flares have occurred in this time. B-class flares are possible
in the following 24-hour period.
The position of NOAA 12680 on 14-Sep-2017 at 13:30 UT is:
