              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Despite some nearby threats at the start of the night, we were able to open shortly after sunset and observe until morning twilight.  There were some occasional struggles with patchy clouds and variable seeing, but never enough to prevent observations.
