Observer Support: 
Hernan Tirado
Night Assistant: 
Alberto Alvarez
Also Present: 
Alfredo Zenteno
Problems: 
At the beginning of the night: the "center" command would not work. We called Diego and he found out that the RA value was empty (shown as ' ' in the image header). We called Omar ​and he fixed the problem by adding a line of code in the TCS computer. After this, the center command worked flawlessly.
At 5:24UT: we had to reboot the DECal computer. 
Comments: 
This was an engineering night used to test DECam after the snow storm and cooling down of the instrument. The night was also used for training G. Damke ​by A. Zenteno.
As a note, the Internet connection was stable and good for the whole night. We observed from the Recinto, in the first half; and from home (outside of the Recinto) for the second half of the night.
