 It was overcast at the beginning of the night. The weather conditions
 deteriorated into high humidity, high winds, fain and fog as it got
 later into the evening.
 2nd Half Observing Specialist: J.Dembicky
 Clouds, Fog, humidity and wind kept us closed all night.  Satellite
 images looked bleak as well.

 remainder of the night and called it quits.
