              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I had to do a startNubs on gcam tonight.
Clouds on and off tonight but it was never really clear.  We observed through them except for the thicker portions.  My 1st half observer finished a little early due to them needing 1hr observations and running out of time at the end due to the clouds.
My observer gave up at 03:15 with the weather outside completely cloudy and not looking like much improvement in the next few hours either.
