(* means a trouble report has been issued or appended to)
The telescope was opened at 18:30 under a clear sky.  The first half
night's weather was great except for a windy interval from 20:50 to
21:50 MST, for which I had to close.  The sky clouded over 1 hour into
Alan Dierck's run.  So, not counting the instrument change, he only
got about 1/2 hour on the sky.
The observers were Gene Magnier and Brook Skelton for UW04 and Alan
Diercks for UW03.  There was some trouble with the DIS instrument
mount this afternoon.  The day staff worked on it and got it in
workable condition in time for the first observers.
