Observer Support: 
Manuel Hernandez
Night Assistant: 
Claudio Aguilera
Also Present: 
Marco, Simon, Rolando (remote from La Serena)
Problems: 

Some minor issues with the GUI and commands that Marco resolved.  Guider was not used at the beginning of the night because we could not connect to he catalog in La Serena.  Simon, Rolando and others worked on this.

Comments: 

(1) Took exposures in JHKs for 1,2,3,4, and 5 sec in all detectors to check linearity of cnts/exptime.  MArco made a prelimenary graph and the uncertainty with exposure times seems to be solved.
(2) Took galaxy template images in JHKs for a kilonovae project for Dave Coulter.
