              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
At checkout: KOSMOS ccd temp 187, NICFPS not connected error. All-sky camera frozen. All-sky camera would not reconnect even after restarting computer.
A storm kept us closed for most of A-half. We got some rain starting at 21:00, and had elevated dust all night. We were able to open once we were clear of radar with good seeing but we had clouds in and out for the rest of the night.
Closed at 04:46 due to dust.
KOSMOS ccd temp 179.5 at end of night.
