              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had a beautiful, clear night!  Seeing never got below a subarcsecond but it was below 2". NM05 had issues with their guide images not downloading and they were logged in with MacOSX 10.12.4.  However, UW06 used the same MacOSX and had no problems.
ARCSAT had issues with flats which Jack and Bill assisted with, but one of the dome motors had a major issue tonight and may have derailed and we couldn't observe for the rest of the night.
