(* means a trouble report has been issued or appended to)
The telescope was opened at 17:00 MST.  The sky was murky all night.
The observers were Alan Diercks for UW01 and Ted Wyder and Brooke
Skelton for UW06.  Both programs used SPIcam.  Ted and Brooke lost a
bit of time due to the guider mac crashing (which required resetting
the guide camera controller).  This was the only guider failure, not
counting the numerous times it lost the guide star due to clouds.
Alan remarked that if we had enough influence to get the clouds
cleared away we could forget the telescope and just ask questions!
I have been using Jeff Morgan's new guide camera focusing script -
very handy!  I also tested Bob Loewenstein's newest version of Remark
which has some fixes to problems in earlier versions.  This version
hasn't been released yet.  I still need to test the changes to the DIS
configuration commands on some calibration images.
The DIS xfer dewar developed a leak, which I was able to fix before it
became a real problem.
			     OBSERVER COMMENTS
Alan (UW01) - "Thanks for having everything ready... Every thing went
very smoothly, except for the clouds it was quite successful."
Ted and Brooke (UW06) - forgot to ask for comments - will get them
when they observe again on monday
