              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear.  The GS01 program went off without a hitch.  Then came the UV01. Things proceeded well, including instrument changes.  The weather cooperated with clear skies and decent seeing. We started to get thin clouds around 04:00. Observing was stopped at 05:45 due to clouds obscuring the target in the west (even though it was mostly clear).
