              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High clouds at the start of the night, medium clouds in the middle
of the night, and then clearing for the last few hours of the night.
Seeing was good throughout.
We had a delay at the start of the night due to the ARCTIC bug where
it doesn't like subframes with odd dimensions.  And another delay at
changeover when I had trouble getting ARCTIC's filter wheel door to
close.  Aside from those short interruptions everything went smoothly.
