                ------------- ACTIVITY LOG --------------
Observing Specialist, 1st Half: Frank Deglman
      PMSS alarm was triggered by switching over to the outer
desiccant canister.  The outer valves were open first and then the
inner were shut off.  The pressure did not drop by much, but enough to
trigger the alarm, which quickly shut back off.
      Opened at 22:20. Obtained only a few DIS spectra, some through
clouds. The huge rapid focus change was probably from late cooling.
Closed at 23:25.
Observing Specialist, 2nd Half: Camron Hastings
      I stayed closed until 03:10 MDT when a hole opened up. We opened
and stayed that way until twilight. All ran smoothly.
