------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff
Clouds coming from the NW caused variable seeing through the first half of
the night.  After 1:30 MDT the skies were photometric.
The dis slitviewer guider crashed twice.  The first time was unknown but
the second was around UT 10:31.  The failure occurred after centering
target on slit and starting guiding.  Restarting the dcam Nubs solved the
problem.
