Dear RHESSI Collaborators,
Solar activity has been at very low levels. A new region is emerging
and forming spots. It produced a long-duration B1 flare just two hours
ago. This event is due to a filament eruption and accompanied by a
weak CME. Today we will watch this new region. B-class flares are
expected with a chance of low C-class events.
The approximate position of the target on November 25 at 08:30 UT is:
N13E03 (-50", 120")

Dear RHESSI Collaborators,
Solar activity continues at extremely low levels. The solar disk
remains spotless and no flares occurred in the past 24 hours.
There are several filaments distributed in the northern and also
southern hemispheres, which appear to be oscillating. The target
plage NOAA 12687 is mostly unchanged. It is rotating to the west
limb. We will watch this plage region for one more day. Only very
low activities are likely in the next 24 hours.
The position of NOAA 12687 on November 24 at 12:30 UT is:
S09W59 (824", -166")

Dear RHESSI Collaborators,
The solar disk remains spotless. The target plage NOAA 12687
was the source of a B1.7 at 09:06 UT today. 12687 is showing
surges. Minor activities are expected in the following 24 hours.
The position of NOAA 12687 on November 23 at 8:30 UT is:
S09W45 (680", -173")

Dear RHESSI Collaborators,
The solar disk remains spotless and no flares occurred again
in the past 24 hours. The target plage NOAA 12687 is creating
a filament. Very minor activities are likely in the next 24 hours.
The position of NOAA 12687 on November 22 at 12:30 UT is:
S09W31 (495", -180")

Quiet conditions should continue in the next 24 hours.

Dear RHESSI Collaborators,
Solar activity continues at an extremely low level with the
GOES soft X-ray flux flat at ~A5. The solar disk is spotless
now. The target plage region NOAA 12687 continues to decay.
No noteworthy events are likely in the following 24 hours.
The position of NOAA 12687 on November 20 at 08:30 UT is:
S09W01 (16", -189")

Dear RHESSI Collaborators,
The level of solar activity is extremely low. NOAA region 12687
has now decayed to plage. No flares have occurred since the last
message. Low B-class flares may be possible in the next 24 hours.
The position of the now decayed NOAA 12687 on 19-Nov-2017 at 23:00 UT is:
S09E05, ( -88",-190" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. The region that was emerging
in the North West quadrant was initially numbered as NOAA 12688, but
already lost its spots. NOAA 12687 decayed since the last message,
losing a significant amount of area coverage in its trailing spot.
B-class activity is possible in the following 24-hour period.
The position of NOAA 12687 on 18-Nov-2017 at 20:30 UT is:
S08E19, ( -314",-173" )

Dear RHESSI Collaborators,
The level of solar activity is very low. A new region is in the early
emergence stage in the North West quadrant, but has not produced any
flaring activity. NOAA 12687 has decayed over the past 24 hours, and
has completely lost its small leading spots. This region produced the
largest magnitude flare since the last message (a B6.2 on 17-Nov-2017
at 00:21 UT). More B-class flares are possible in the next 24 hours.
The position of NOAA 12687 on 17-Nov-2017 at 23:00 UT is:
S08E23, ( -427", -173" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA region 12687 has grown
slightly in spot area since the last message due to consolidation
of its dominant trailing spot. This region has remained classified
as a beta/C-type sunspot group and was the source a B3.7 flare on
16-Nov-2017 at 13:03 UT, the largest event in the period. Further
B-class activity is possible in the next 24 hours, with a chance
of an isolated low C-class flare.
The position of NOAA 12687 on 16-Nov-2017 at 22:30 UT is:
S07E43, ( -653", -151" )
