                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Cloudy skies and local radar returns delayed opening. Cleared enough to open around
20:30; still struggled with passing clouds for a few hours but then cleared pretty
nicely. Seeing was around 1.2" most of first half stabilizing around midnight to
1.0" or less into second half. Humidity became a problem second half and we had to
close a little after 04:00.
No problems.
