Telescope: 
CTIO Blanco 4-m
Submitter: 
Alfredo Zenteno & Guillermo Damke (1st) / Maria Acevedo (2nd)
Submitter Email: 
alfredo.zenteno@noirlab.edu
Observer Support: 
Hernan Tirado
Night Assistant: 
Alberto Alvarez
Also Present: 
Roberto Avilés
Problems: 

4MAP failed at 2:34 local time. Telescope slewed to zenith and restarted. SISPI "reset' hit after. Only 3 minutes lost.

Observer4's ExposureServer2 failed twice. First, it stopped copying images during calibrations in the afternoon. It was recovered by SISPI's restart (restarting the role did not fix it). However, it failed again around 21:59 local time (last exposure in observer4 is 1378453).

Comments: 

Engineering test worked well. Hexapod parameters changed with the help of Roberto Aviles and Alberto Alvarez.
