                 ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Snow this afternoon and early evening. Conditions were too humid to
 even consider opening all night. The day staff did clean a great deal
 of snow off the enclosure roof this afternoon however there was about
 an inch of new accumulation by the time the deeper drifts had been
 cleared away. I spent the evening testing an interface between TUI
 and XEphem. I reported a few bugs and suggestions to Matt Nelson.
 He was online making software changes as I emailed him recommendations.
 Second half I further familiarized myself with XEphem and working on
 a variety of small projects and tasks.
 When I checked the roof this morning there was some minor drifting near
 the edges of the building and more serious drifts near the back of the
 roof. However, the roof was mostly free of snow. The exposure to sun
 light today should melt most of what I could see.
