Observer Support: 
Alfredo Zenteno
Night Assistant: 
Claudio Aguilera
Also Present: 
Manuel Hernandez
Problems: 

At UT 23:00 a rubber drive band attached to some pump failed.  We discovered this when fire alarms started going off.  The CTIO team responded rapidly and replaced the band; we lost only 30 minutes.  We needed to decamp to the 1.5 m for the first half of the night while the 4m control room aired out.

Comments: 

Another beautiful, cloudless, subarcsecond night.
