                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
Clouds prevented opening on schedule.  They thinned around 19:10 and I
turned the exhaust fans on/opened louvers and opened the enclosure up at
19:15.  Handed the instrument over to the observer at 19:22. Humidity
increased to closure limit (and clouds thickened at 19:50) which forced
closure of the telescope for the remainder of the 1st half.
L. Homer was training on the 3.5m again tonight.
 Observing Specialist, 2nd Shift: Noel Camron Hastings
    Did not open due to high humidity, blowing snow and high winds. I
turned the SPIcam Cryo-Tiger off around 01:00 MST to allow it to begin
warming in preparation for disassembly.
