              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Humidity and clouds to start the night. We had some clearing but precip just to our West (moving up from the South) and humidity right at the limit, so I opted to stay close until things improved for the better.
We did manage to get on sky for the 2nd program for 30 mins and fought clouds and humidity for most of the 2nd half.  by 05:00 we were getting pretty cloudy and decided to give up a few mins later.
