              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Very productive night with great seeing.  We were chasing falling temperatures all night, and never found a good equilibrium.  Had one wave of clouds that didn't cause any trouble, and the cold front hit us very early int he morning.  Overall a smooth night.
The ecam froze up silently once during observing, but I was able to recover it with no time lost and the star had not drifted.
