(* means a trouble report has been issued or appended to)
The telescope was opened at 17:10 MST and closed at 20:15, due to
clouds.  The observing specialists for the first half of the night
were Dan Long and Tia Hoyes.
The observers were Rosie Wyse for JH01, Gordon Richards for UC11, and
myself for PU01.
Rosie had a little time on the sky before the clouds came in, but was
clouded out for the remainder.  The other programs were completely
clouded out.  Gordon used his time to take DIS gain and linearity data
(needed for his science data reduction).  He and I also tested version
2.38a1 of Remark, which has a fix to an earlier problem with DIS
grating setting control.  Dan encountered a Reamrk failure early in
the evening, but I wasn't able to reproduce it later.  I'll go over
that with him in the afternoon.
