Weather conditions: clear, windstill, humidity 48%, seeing (DIMM) ~0.9"

00:40 UT: follow up of AT2016iks, gr11+gr16+flat (we started before twilight ended)
02:03 UT: Standard star vma2
02:35 UT: refocusing
02:40 UT: Follow up of AT2016hmq (2x1800s), seeing ~1", humidity 50%, windstill
03:52 UT: Follow up of SN2016ipf (g11+g16), seeing still ~1", humidity 55%, wind 2.2m/s
