                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Cirrus came and went throughout the night. Winds were not as strong as
 predicted and the mirror temperature was below freezing so blowing snow
 was not as much of a concern as it was for the 2.5m. We were open all night
 with reasonable seeing. No problems.
