(* means a trouble report has been issued or appended to)
The telescope was opened at 17:30.  Tom Harrison was observing for NM11.
He observed stars in two Gamma Ray Burst fields.  I did not get any comments
from him(I forgot to ask).
Gordon Richards was observing for UC10.
Comments:The last half of the night was fairly productive despite the overhead
due to the slit viewer.  We shot a number of QSO candidates and got
slitless spectra of a standard with both the low and medium resolution
gratings for a throughput comparison.
Gordon
I was the observer for the Lens Monitoring Run.  I observed 0957 and 1120.
No problems to speak of.
