                ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Coughlin, J. Huehnerhoff
A clear night with clouds early in the night on the horizon.
Spicam not responsive upon instrument checkout (UT 00:20).  Not corrected by
restarting the ICC, or Hub.  A hard restart on Spicam corrected the problem.
Spicam functioned properly the rest of the scheduled time (first half).
Rotating the instrument to 0 when changing filters prevented any problem in
filter wheel error.
NICFPS used on second half with observers on site.  Clouds encroaching from
the south around 04:30 MST.  NICFPS removed and GFP installed at UT 11:10.
GFP CCD running warm (-90K) according to GFP group.  GFP was able to image a
star but the instrument was still having trouble with electronics.
