              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had a dust event around 04:00UT.
Another dust event at 07:50UT
Another dust event at 08:20UT
Please CO2 clean mirror tomorrow
Closed at 08:40 due to dust/humidity combo.  I saw fog forming to our west as the cold front pushed westward over us and dropped into the basin.  Seeing was very poor as well.
We called it a night at 04:00MDT with humidity/temp/dust jumping all over the place.
