              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
- dataq needed a restart during checkout
- Alcor camera needed the USB restart twice at the beginning of the night
A beautiful night! the clouds cleared up by sunset and the seeing was excellent all
night! The wind shifted a few times but it never affected science. What a great
night to be back!!
