(* means a trouble report has been issued or appended to)
Charles Corson was the observing specialist for the first half of the
night.
The telescope was opened at 21:10 MDT.  Equipment problems delayed the
start of observing until 22:30 MDT.  The telescope was closed at 03:00
MDT, due to a high level of airborne particles (dust or pollen)
observed in my flashlight beam.
*During the first half of the night, the telescope altitude drive ran
away and drove the telescope into the zenith limit (no damage to the
telescope).  Charles has issued a problem report.
Engineering work was done on the instrument blocks, with Russ Owen
observing remotely from UW, assisted by myself and Charles Corson.
Data was obtained with specially prepared instrument block files to
track down some bugs in the instrument data fitting routine.  The dust
closure prevented Russ from completing the guider instrument block
data set.
