                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
AzVeloScale: 578.8, 577.2; 578.0 (changed to 578)
High winds, clouds and local radar activity kept us closed for a few hours at the
start of the night. Clouds thinned and winds calmed, but some cirrus remained all
night.
No problems.
