              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Nicfps was reading out as 0 on half the chip and needed an init. Gcam needed a hub restart at checkout. The beginning of the night started out well, with clear skies and moderate seeing. But then the humidity started going up and the clouds appeared around midnight. Fog was starting to roll over us so I closed up. It started raining at 1 am along with winds near 40mph and there just wasn't any hope after that.  The humidity and clouds stayed high the whole time with fog rolling in and out. I called it quits at 5:15.
