Observer Support: 
Alberto Alvarez
Night Assistant: 
Mauricio Rojas
Problems: 

# At 00:30: 238024 TCS gui froze.  Problem with TCS. We noticed that there were large waits after exposure 238024, eventhough the telescope was in position and the TCS ready light was not green, but "in position" was green.
# Alberto reboots TCS. 
# As a result exposures 27 to 29 were not delivered.

# At 5:10, we noticed that RASICAM stopped working. It was back at 5.28.
 

Comments: 
# DIMM not available
# At 22:15, we closed the louvers (wind coming from behind the telescope)
# At 02:25, we asked the operator to close the wind screen
