              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The power was restored and we are no longer on generator! We were able to open on time but we did have to fight the wind and clouds forming over us. That being said, seeing was good until about 4 am and it didn't improve.
No problems tonight.
