                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVeloScale: 581.4, 580.2; 580.8 (no change)
Thin clouds on and off most of the night. We began with decent seeing which degraded
substantially (near 5" at times) just after midnight; slowly improving after a few
hours, still highly variable.
Pointing was very good with all three instruments at NA2. No problems.
