                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 The night started ut well with uniform cirrus and excellent seeing
 but conditions slowly deteriorated until we the first half users
 gave up on even their brightest targets. We closed at midnight as
 radar returns started to appear in the area and the thicker clouds
 rolled in. We never reopened. At 06:30 it started to snow.
 We had some computer related problems at the start of the night.
 The vnc server for the GFP was running painfully slow and required
 a restart. The Obs-specs main observing computer died at the start
 of the night. Likely a failed hard drive. I was able to run TUI on
 my laptop.
