Science:

23:45 We start with SOFI

23:50 Image analysis and telescope focus

00:05 Some bumps with the visitor computer, it seems fixed now

00:10 OGLE16euo, JHK, seeing ~0.7”

01:35 Telescope focus

01:40 Feige 110, flux standard for SOFI, seeing ~0.8”

01:55 Hip10990, telluric standard for SN2016hnk, seeing ~0.7”

02:00 SN2016hnk, BG, seeing ~0.8”

03:25 We have continuous problems with the p2pp system, the loading of the OBs from the visitor terminal to the TO’s terminal is either extremely slow or sometimes crashes. We try to find a solution, but we waste some time.
