Observer Support: 
Hernan Tirado
Night Assistant: 
Leonardo Paredes
Also Present: 
Matt Wiesner, Marisa March
Problems: 

At 06:14UT we had a LN2 alarm glycol over-temperature caused by the 40T chiller tripping. Attempts by CTIO staff to reset the alarm and restart the chiller were not successful so they proceeded to switch to the backup but this took until 08:30UT so effectively ended observing for the night.
