The telescope was open tonight at 18:55. Dave Cole was available for the Adler
run this evening.
Comments:Our final twilight observing session of the season went very well
indeed: we obtained time series for four asteroids, more than on any
of our previous Friday evenings.  The observatory ran like clockwork
tonight.
Dave
I observed for the Lens Monitoring, 0957.  No problems, although I thought we
were going to begin using SPICAM.  I had to use DIS because there was not any
time scheduled for the instrument change.
Gordon Richards had the second half of the night.
Comments: Very nice night tonight.  Things went very smoothly.  Just a few
clouds, but no other problems to speak of.  We got about 3.5 hours of spectra
on our QSO absorption line targets.
