(* means a trouble report has been issued or appended to)
1st half observing specialist: McMillan
First half was partly cloudy; the telescope was closed from 21:15 to
22:10 due to clouds, but some of the open time was unusable as well.
* I had considerable trouble mounting DIS, which might be related to
the earlier trouble with the rotator either as cause or effect.  DIS
was also having some nitrogen difficulties, although it managed to
stay cool.  We saw occasional image motion of approx 2-3 arcsec, but
we were using various rotations so I'm not sure of the direction.
2nd half observing specialist: Deglman
Gordon Richards oberved with DIS for UC01.  Most of the time was lost to
clouds.  Closed at 01:30 and did not reopen.  Some of this time was spent
obtaining calibration spectra.
