Partly cloudy night with mostly variable seeing, and the relative humidity closed us early again for a while, only to open up to nasty nasty clouds. So we only managed to take science data for our lowest priority targets, which were the only ones available for poor conditions:

2016-2-SCI-034 P3 HRS (Searching for evolved binary stars with long orbital periods)
2016-2-SCI-047 P4 RSS (x3) (Monitoring the line emission in Southern Galactic Be/X-ray binaries)
