Observing Summary:

Operated all night, getting parallax measurements for
13 nearby star targets. Decreasing temperatures and
increasing wind -- it's getting chilly up here!

I saw a bright 'star' slowly moving across the field of
the guide camera around 3am. The thing was 7th-8th magnitude. 
Must have been a big satellite -- I wonder if it was 
the ISS. Spooky!

No problems encountered.
