              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A good night! You know, for the most part. I thought it was going to be totally photometric. It totally wasn't. We had thin clouds rolling over us for over half the nights. Just enough to be annoying. Seeing was GOD AWFUL!! It wasn't windy or dusty but there must have been some great turbulence in the upper atmosphere.
No problems tonight.
