                               ACTIVITY LOG
The telescope was open at 00:30 after waiting for high winds, high dust counts,
and overcast skies to subside.  The Lens Monitoring program could not be done
due to weather.
Chris Stubbs was available for the first half of the evening, but we could not
open until 00:30, which only left him a half hour.  He gave the time to
UW01.
Don Hoard was the observer for UW01.  We had to close at 3:00 due to humidity
and overcast skies.  Reopened at 04:45.  Very unstable evening.
Comments:I obtained good spectra whenever the weather let us open.  The only
non-weather problem was some difficulty getting the guider running the
first time.
I just had to cycle the power on the guider, and it was fine.
