(* means a trouble report has been issued or appended to)
The telescope was opened at 19:45 MDT.  The WS01 program scheduled for
the first half of the night was cancelled, so that half was
rescheduled.  The observers were myself for DD04, Marla Geha for NM05,
and Alan Diercks for UW03.
*I had some trouble image quality at the beginning of the night
(twilight).  Possibly due to the primary mirror support system.  I was
able to get 1.0 arcsec at best focus, though.
