Also Present: 
Anna Patej, Brian Nord
Problems: 

No major problems.

We had the usual pointing zero point problems at high airmass. 
We experimented with the "wait":"autocorrect" command in the SISPI scripts, but we don't think this did anything.
Two pointings were rejected by the telescope because they were at too high airmass or had RA=360.000 - we've fixed our script.

Seeing was good, but some high cirrus in the latter half of the night.
