              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started off with high clouds and hazes which pretty much powered through the whole night.  Seeing was moderate expect for a couple hours near midnight when it was subarcsecond. The first OU group has arrived and had some TUI practice tonight.
No problems tonight.
