Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12628 showed some
growth in spot area and magnetic polarity mixing since the last
message, and it is currently classified as a beta-gamma/D-type
sunspot group. This region produced the only flare in the past
24 hours, a B2.4 on 22-Jan-2017 at 12:23 UT. B-class flares are
expected over the following 24 hours, with a chance for C-class.
The position of NOAA 12628 on 22-Jan-2017 at 19:30 UT is:
N12E25, ( -408", 282" )

Dear RHESSI Collaborators,
Solar activity is now at a low level. Yesterday's target region
continued to emerge new magnetic flux and has been designated as
NOAA 12628. This region was classified at the beginning of the UT
day as a beta/B-type sunspot group, but now appears to display a
beta/D-type classification. 12628 has been the most flare-active
region since the last message with producing nine B-class and six
C-class events, the largest being a C9.3 flare on 21-Jan-2017 at
07:14 UT. Further C-class activity is likely in the next 24 hours,
with a small chance for a low M-class flare if 12628 continues to
emerge magnetic flux.
The position of NOAA 12628 on 21-Jan-2017 at 22:00 UT is:
N12E37, ( -574", 272" )

Dear RHESSI Collaborators,
The level of solar activity has risen to very low. NOAA 12626 continued
to decay while two spotted (but currently unnumbered) regions emerged in
the North East quadrant. Both regions appear to be beta/C-type sunspot
groups and have produced B-class activity. The target region will be the
one that lies further East, which produced both the most flares and the
largest flare since the last message (a B5.3 on 20-Jan-2017 at 10:37 UT).
More B-class flares are expected in the next 24-hour period.
The approximate position of this region on 20-Jan-2017 at 22:00 UT is:
N11E52, ( -753", 239" )

Dear RHESSI Collaborators,
Solar activity remains at an extremely low level. NOAA 12626 decayed
once again, decreasing slightly in number of spots and area, and also
being classified as an alpha/H-type sunspot group. There have been no
flares since the last message. No significant activity is expected in
the following 24 hours.
The position of NOAA 12626 on 19-Jan-2017 at 19:30 UT is:
N07W08, ( 132", 203" )

Dear RHESSI Collaborators,
The level of solar activity continues to be extremely low. NOAA 12626
has decreased slightly in spot area, but increased in classification
to a beta/C-type sunspot group. Again, no flares have occurred since
the last message. No significant activity is expected in the next 24
hours.
The position of NOAA 12626 on 18-Jan-2017 at 19:30 UT is:
N08E05, ( -88", 219" )

Dear RHESSI Collaborators,
Solar activity is extremely low. NOAA 12626 has decayed slightly in
spot area, but remains classified as an alpha/H-type sunspot group.
No flares have been observed since the last message. Low B-class may
be possible over the following 24 hours.
The position of NOAA 12626 on 17-Jan-2017 at 19:30 UT is:
N08E18, ( -303", 213" )

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target NOAA 12625
has decayed somewhat to an alpha/H-type sunspot group. The new target
will be NOAA 12626 that is also designated as an alpha/A-type sunspot
group, but with larger spot area. Both regions have produced a single
low B-class flare since the last message. Further low B-class flares
may be possible in the next 24-hour period.
The position of this NOAA 12626 on 16-Jan-2017 at 23:00 UT is:
N09E29, ( -473", 222" )

Dear RHESSI Collaborators,
The GOES X-ray flux has been flat at the ~A7 background
level. The target region NOAA 12625 and the other sunspot
region NOAA 12626 (N08E46) on the visible disk are mostly
unchanged. Target 12625 remains a beta/C-type sunspot
group. It is displaying some ephemeral jets on the edge of the
region. If possible, also include 12626 within the field-of-view.
Only minor activities are expected in the following 24 hours.
The position of NOAA 12625 on January 15 at 14:30 UT is:
N03E36 (-574", 114")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. There are currently
two sunspot regions on the visible disk, the target region
NOAA 12625 and its neighbour NOAA 12626 (N08E58). 12626
having an Alpha/H-type classification produced the largest event
(a B2.1 at 07:08 UT today) since the last message. The target
region NOAA 12625 has been designated as a beta/C-type
configuration increasing in sunspot area and number of spots
slightly. If possible, also include the neighbour region 12626 within
the field-of-view. B-class activities are possible in the next 24 hours.
The position of NOAA 12625 on January 14 at 14:30 UT is:
N03E49 (-737", 101")

Dear RHESSI Collaborators,
Solar activity has been at extremely low with the X-ray flux
flat at the ~A6 level since the C3.8 flare. The target sunspot
region has been designated as NOAA 12625, with an Alpha/
H-type classification. 12625 is rotating onto the visible disk.
It shows some dynamic surges in H-alpha images. B-class
activities are likely with a chance of low C-class events.
The position of NOAA 12625 on January 13 at 14:30 UT is:
N03E63 (-869", 85")
