              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Wind and high dust levels during first half.  Opened after weather
cleared, had to close after an hour due to increasing cloud cover and
local radar returns.
Started snow program after it started to snow, decent wind should help to
clear building.  Telescope parked facing south.  Minimal snow
accumulation, maybe 0.25".
Echelle autofill working properly.
