              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Weather was not great for the start of the night.  Rain in the county delayed opening for a bit.  Opened at 17:33 when threat of rain had passed.
Starting around 18:15, humidity began to rise. A visual check outside revealed  fog clouds a few dozen feet overhead, and we were forced to close at 18:57.
High humidity turned to fog between 21:00 and 22:00.
AD02 was fogged out.  UW13 started with fog still in effect.
UW13 signed out at 4:45, not having enough time left to do any science.  At that point, we called it a night.
