              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
BRRRR!!! It got so cold tonight! -10C! While the sky was clear, seeing was atrocious at the beginning of the night, fluctuating around 3-5". As the winds shifted and calmed, the seeing improved greatly.  All in all, a fairly good night.
No problems tonight.
