              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with clouds which eventually, mostly cleared as the night progressed. The seeing was never very good but everyone was able to take their data. The OU01 class powered through B half like champs and got the first of their three nights under their belt!
NM01 needed the DIS 5" slit in the slit wheel, which means I had to pull the wheel out. But I made all new masks for the wheel.
No problems tonight. Telescope parked at az -40.
