              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Clouds on and off most of the night with periods of clear skies. Closed briefly
during first half due to clouds and radar returns. Good seeing. No problems.
Guiding second half with Agile guider. Observer reports: "It worked like a charm.
The stars did not wander by more than 2 pixels the entire night."
