              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Most of the night was clear, with poor to very bad seeing.  A line of clouds passed through for just under two hours, with some spotty radar that persuaded me to close for a portion of that.  ARCTIC and Agile are down, but everything else worked well.
