              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Thin annoying clouds at the start of the night which cleared up but then got worse again after midnight. The JHU got to see some cool things with the eyepiece tonight, the clouds behaved themselves while we were up in the dome!
Focused KOSMOS in imaging mode.
JH05 handed over to CG01 a few minutes early.
