                 ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Night went smoothly with moderate seeing until the sky became opaque at 22:50.
 Closed and didnt reopen rest of the night. I used the rest of the night to
 exercise the echelle slitviewer. It crashed once and I reported the event
 specifics to the interested parties. Humidity spiked at about 05:00 when I was
 starting end of night tasks.
