Telescope: 
CTIO Blanco 4-m
Submitter:

Observer Support: 
Rodrigo Hernandez
Night Assistant: 
Alberto Alvarez
Problems: 

None. Telescope worked well. The only minor problem was a small earthquake about 11.40 pm CLST. We lost the drive and then the 4MAP mirror actuator, but thanks to Alberto's quick action and knowledge of the procedure, we went back to zenith and were able to get back online about 5 mins later and take the next science image.

Comments:
