              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A nice, uneventful evening. We were stuck with clouds from the beginning of the night and, while we were able to punch through them, they just kept getting thicker and more annoying. But, no time was lost and the seeing was actually pretty good!
No problems tonight.
