              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night lulled me into a false sense of security by starting out clear and breezy.  By 22:00 it had become cloudy and very windy.  While gusts were at 40mph, we were able to stay open given that we pointed directly away from the wind.  Dust counts increased to warning levels for about an hour before dropping again.
Around 05:45 the dust spiked inside the dome.  I closed as quickly as possible but 1.0um dust counts went up to 5000.
No problems tonight
