              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Radar and clouds and then rain, thunderstorms, and fog kept us closed all night.
We did verify ACS functionality in-dome and did a little bit of ATUI training.
DIS red temp was 270K around 17:45 but down to 183 at 04:50.
