(* means a trouble report has been issued or appended to)
The telescope was opened at 18:45.  The weather was ideal.
I observed for PU01 and obtained images of two gravitational lenses.
No problems were encountered during this run.
Dan Zucker and Ted Wyder were the observers for UW13.  They had a very
productive run, with a couple small glitches.  One of their first
exposures was taken through the wrong filter due to my incorrect
editing of the filter text file.  This mistake was spotted pretty
quickly.  The guide camera was utilized for all of the long exposures.
This was a great success, with the exception of one image during which
the guider had stopped.  The guide camera Macintosh crashed once
during the night.  Camera and Mac had to be restarted, but this didn't
take very long.
