Observed SMC and LMC targets with N708 filter to test its suitability for use in continuum-subtraction of N662 and N673 filter data. Didn't have trouble with AOS and images showed low-ellipticity. The hexapod showed update tweaks in x-,y-position and tip/tilt all night according to the ICS. Fairly smooth night execpt for clouds over LMC during 3rd quarter. Generally poor seeing during 4th quarter ~1.5" on average. Because of non-photometric conditions, starflats were not attempted in i and z.
Alfredo used 30min of dark time and ~1" seeing during the first part of the night to take some images for program N2019A-0308 for Ian Dell'antonio.
Many thanks to Tim, Alfredo, and Guillermo for their help in getting me started each night and to Manuel and Claudio for their support.
