Observing Summary:


Parallax observations.  The night started and ended with good 
conditions, but there were a few rough hours in the middle,
with bad seeing and moonlit cirrus.  I stopped observing then
and used some of the time to work on the 1.3m guide probe
geometry.  

The HA encoder is still misbehaving, and was a bit more trouble
tonight.  See separate report for details.
