Observing Summary:

Everything worked well tonight except ~2 hours into the night the 
telescope pointing seemed to go way off.  I had just set the RA/DEC
encoders on the last target using the centermdm program.  I suspect
the strange off pointing was my own fault (not like last
night where it just seemed to get way off on its own).  I possibly had
the wrong object qued up (although I can't imagine how that happened).  

At any rate I had to reset the pointing once again but this time it only
took 15 minutes (John had told me about the post it note on the glass window 
by the control room door that had the correct tilt degrees).  

There were high cirrus throughout the night.  

The pointing and tracking of the telescope worked wonderfully.
