              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had thunderstorms this afternoon with lingering virga at sunset. Things cleared up a few hours later and we were able to open with surprisingly good seeing! Clouds started rolling back in but they weren't dangerous and we were able to stay open all night. There was a wind shift during B half and seeing went to hell.
No problems tonight.
