              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening start clear and calm with so-so seeing. Dcam shutter was not closing properly again tonight.  Seeing improved by 22:00. Not a cloud was seen all night, and aside from the dcam shutter, no other malfunctions.  It was a blissfully boring night. All programs got their full sky times.
