                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 During checkout I attempted to move the tertiary to BC1 from NA2
 and the clamp failed to open. The first home of the tertiary failed
 to open the clamp, a second worked fine. Subsequent moves of the
 tertiary worked fine.
 High winds and dust kept us closed until after 2am. When we did
 open seeing was moderate during initial focusing but quickly
 degraded to horrible. Seeing never improved to below 2 arcseconds
 for the remainder of the night.
 No other problems.
