Observer Support: 
Guillermo Damke
Night Assistant: 
Alberto Alvarez
Also Present: 
Hernan Tirado, Erik Wasleske
Problems: 

Will Cerny (second half observer): ran into telescope issue at 09:56 UTC. To the best of my understanding, Alberto says we lost tracking and ran into a possible issue with air for mirror support. We ended science observations a bit early because of this issue.
