(* means a trouble report has been issued or appended to)
The telescope was opened at 20:15.  Chris Stubbs and the students from UW
were on site for telescope training.  They made use of GRIM2 to obtain images
of test objects and practice working with the telescope.
We were closed for four hours due to high dust counts and degraded conditions.
Charles Corson was the observing specialist for the first half of the evening,
and he tested the Guider.  He found that it will centroid, and the
track/pterr is functional, but he could not guide and the instrument would
not take an exposure.
I was the observer for the Lens Monitoring run, and since I could not open
until 4:05, I could only obtain data for 2237.
