              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear all night, with surprising good seeing despite an east wind.  I was a little bit worried about dust counts so I didn't open or ventilate until right at sunset, and then the focus changed fairly rapidly, but everything worked well.
The first two programs reached an agreement about time-sharing which made them both happy, so that was fine with me.
