              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Another windy, dusty night.  I was able to open 15min before sunset and the dust hovered at closing level nearly all night.  I was not able to open the louvers or turn on the fans which resulted in poor seeing.
No problems tonight.
