              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
The evening greeted us with high winds, moderate dust and rising humidity.  Slew tests were not performed during checkout on account of the wind.  After sunset, the humidity rose to high levels, and we remained closed. Winds and humidity continued to stay high through 0300.  Wind started to die down around 0400, but the humidity did not drop. We did not open, aside from about one minute in order to let a bat out of the dome (plus side: he/she took care of the moths!) At 4:45 with twlilight approaching, we called it a night.  No programs got data.
