(* means a trouble report has been issued or appended to)
The telescope was opened at 20:05.  At this time, Chris Stubbs used the SLOAN
filters to obtain twilight flats.  He completed this by 20:45, so as not to
interfere with the Lens Monitoring. (This schedule change was agreed upon by
the site manager)
I began the Lens Monitoring at 21:15.  The skies quickly became overcast, and
most of the images did not come out very well.  I persisted taking images of
0957, but concluded at 21:55 when the clouds completely covered the sky.
Mike Strauss and Chris Stubbs then waited for the overcast conditions to
end.  We reopened at 1:30 when there was somewhat of a clearing trend.  Chris
continued collecting data for the remainder of the evening between gaps in the
clouds.  He seemed to collect quite a few good images, nonetheless.
