                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
After the observer got flats and while we were attempting focus clouds moved in
rapidly and dust levels spiked. I closed until about 2300 when the skies
became clear and dust levels dropped. Focus was diffiuclt since the dome air
was quite turbulent and the temperatures had not quite equalized ealier in the
evening. We were forced to focus again shortly after midnight however clouds
again closed in on us and remained over head the remainder of the night.
