              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The strip chart needed to be restarted at the beginning of the night.  The night started clear and gorgeous! And we had so many onsite observers! :D But none of them brought me pie :(
Seeing was meh for most of the night until the wind changed and seeing trainwrecked.  After the wind changed back to the west, seeing improved to subarcsecond.
No problems tonight.
