Observing Specialist: N.C.Hastings
    We opened at 19:30 MST amidst high humidity and fast clouds. It
was obvious that we would be lucky to get any time at all before we
closed, which happened at 21:55 MST, one minute before start time! We
did manage to get two spectrum though, after a fast focus by eye using
the slit camera! We remained closed the rest of the evening due to
high humidity.
    The DIS slit viewer had problems reading sub frames when we tried
to guide. It seems that the communication speed was too fast, it has
been dropped to 33.6k from 57.6k.

used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
