                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
Turned 0n enclosure fans/opened louvers at 17:45, opened enclosure at
18:00 under partly cloudy skies which persisted for the whole of the 1st
half.  I closed the enclosure due to clouds at 23:15.
Jon was installing slitmasks this afternoon while I was checking
out the instruments out.  I turned DIS over to him for taking his cals
early (17:00).
 Observing Specialist, 2nd Shift: Noel Camron Hastings
    The clouds thickened up when I arrived enough that we closed at 23:20
MST and remained so for the rest of the evening.
