              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had clear weather for most of the night, with decent but not great seeing.  Despite some threatening clouds to the south around midnight, we were able to stay open all night, and observations went smoothly with all instruments.
