                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 It snowed a few inches much of first half. Humidity dropped around
 01:30 and the skies cleared some shortly after that but with at least
 2 inches of accumulation on the dome I called it an early night. Around
 04:30, winds were climbing towards 20 mph and I ran the snow program
 for a short time.
