              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Most of the night was lost to clouds, nearby radar returns, and high humidity.  Managed to open at the every end of the night, and pushed the humidity to absolute limits.
Tested the Shack-Hartmann repeatability in (sort of) cold temperatures.  It was very repeatable, the reference LED came back to the same spot every time.
