              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Wind, dust, thunderstorms. We got a little rain! But not very good observing conditions. When it did finally clear up, the dust counts also went back up. We did not open tonight.
No telescope or instrument problems though!
