Comments: 

DECam engineering night. Star flats taken in the 8 filters installed: N964, u, g, r, i, VR, z and Y. All done without any problem. 

Photometric night but with variable seeing (0.9''-2.5'') and windy (with wind gusts of ~20mph). Side doors had to be close twice due to the high wind speed.
