              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland,C.Gray
Cals were being taken at the beginning of the night, which delayed start time.
Clouds were a pain for most of A-half, but thankfully they cleared.
Wind had us pause observations for a while at 3:30am, but it was never enough to close.
No telescope or instrument problems tonight.
