              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Upon open mirror covers at checkout, frost was seen around the perimeter
of the primary.  Decided that there was nothing helpful to do before
opening and started normal operations.  Frost evaporated by 20:00MST.  No
sign of frost or residue on primary in the morning.
Echelle interorder light checked, ratio was calculated to be 16, which is
good.
dcam shutter continuing to stick.
Clear skies with blowing snow at the start of the night.  Closed at 22:50
due to extensive cloud cover, radar returns formed minutes later.  Opened
after radar returns passed.
