                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 About an 1/8 of an inch of snow accumulation the beginning of the
 evening. High winds and blowing snow kept us closed the entire
 night. We saw one failure in tertiary rotation going to Apollo
 last night. The errors were small but the clamp failed to close.
 Rehoming seemed to correct the problem.
