              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We got a few inches of snow last night/this morning. Extra restrictions due to the snow kept us closed for the whole night, as gust speeds (and wind speeds for most of the night) were over 15mph.
Telescope parked at 0,20 because there was still some snow on the roof around when I looked out the hatch during afternoon checkout.
No telescope or instrument problems.
