              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Some thin clouds first half, clear second half.  Variable seeing,
sometimes very good.
I obtained two pointing models in opposite directions, both of them
showing little offset in the overlap region as well as good agreement with
each other.  In addition, I got Shack-Hartmann data at varying
brightnesses to test how the reduction quality varies with signal level.
And a full set of Fastcam data with moderate winds (15-20 mph).
