              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Closed in middle of first half due to local radar returns and cloudy
skies, science was not possible through thick cloud cover.  Opened when
skies cleared enough for safe operation.
Decent seeing the entire night with some short periods of variable/poor
seeing.
