              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
First rotation test slew got a "cannot compute" error, re-initialized axes and tried tcc rot command again, which worked.
Thin clouds on and off all night, a little bit of humidity in the middle of the night, and a few times where wind gusts got a bit high. We had to close for a little over an hour due to the wind gusts.
