              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with high dust and rain all around us. Once the clouds cleared, the humidity increased. Then more radar. After 2am things had calmed down enough that it was safe to open and we were able to stay open the remainder of the night.
No problems tonight.
