                ------------- ACTIVITY LOG --------------
 Observing Specialists:  W.Ketzeback, J.Coughlin
 Clear skies all night. Elevated dewpoint depression keep us closed
 for the start of the night and then forced us to close for about 30
 minutes within an hour of opening. We found the louvers to be frozen
 shut. We attempted to open them in auto and manual modes but the
 linkages would only move a short distance before stopping.
 Started training of Jeff tonight.
 No other problems tonight.
