Observing Summary:


Hello -

Program completed -  mostly a clear start with small patches of clouds
that were not in any of the target way for at least the first 4 hours.
At around 0300-UT Cirrus increasingly moved in to finally cover the
sky at the end of the night -- So I decided to close about a 1/2 of an hour
early.  Gone to catch some zzzzzs...

Again, very variable seeing throughout the night.

XTE	:  19.1
Aql	:   3.58

cheers
