              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out beautiful! Not a cloud in the sky! Seeing was moderate. Then, around 9pm clouds started rolling in. They got really thick around 2am but we were able to fight through until they cleared up beautifully again around 4am.
No problems tonight.
