Night Assistant: 
Claudio Aguilera
Problems: 

[AR] Some infrared camera's were turned on in the dome at the beginning of the night. I realized that something was wrong when the sky did not go down and stayed at 11K ADU in z band. The night assistant turned them off, and then the problem was solved.

[SGG] Nothing to add.
