              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out like all the rest...dark, gray, looming rain.  Things cleared up enough to open at 21:15 and the seeing wasn't half bad. I closed for an hour in B half when clouds and radar started approaching but all ended up being fine and we were able to continue observing (through clouds and such) the remainder of the night.
