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

Initially lost focus before we started the run, but Hernan got it back up and running before we hit -10 degrees, well before I would have started observing. Exposures 8449 through 8452 are really oversaturated (at the worst, ~39000 count, nothing more than that) because there was a problem with our script, fixed now. Randomly got disconnected from the Tololo VPN, managed to get connected again and nothing was interrupted.
