                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 High wind and dust levels the beginning of the night. At 21:00 the cloud
 cover broke, winds subsided and dust levels were below the limits so I
 opened thinking we would get a few hours before the next system hit the
 area. The clouds quickly came back and we never got anything useful in
 the hour and a half we were open. We were forced to close again when
 the dust counts again climbed above the limit.
 I spent much of the night creating and updating a new software mask for
 the cloud camera webpage.
