             ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
It was mostly clear first half, but by midnight some orographic clouds were forming and they gradually got worse during second half.  Seeing was quite good when we measured it but I did see some poofy images in some parts of the sky.  OU03 stopped a little earlier than scheduled because they just weren't getting anything through the clouds, but then APOLLO was able to garner a few photons in occasional holes.
