Night Report 2017-02-06

Observer: Francesco Taddia
TAT on duty: Janet Chen, Lluís Galbany 
Support team: Cristina Barbarino, Anders Nyholm, Emir Karamehmetoglu, Jesper Sollerman

Daytime calibrations: PESSTO_bias, PESSTO_calib (only arcs) --please consider only the calibrations taken after the night
 due to some instrument problems before the night 

Twilight calibrations: BgVri sky flats taken in the morning

seeing 0.85" at 04:19, it jumped to higher values before that.

Weather: clear sky.

00:16 image analysis, problems with the instrument, the images do no show signal from any sources, like there was an interruption of the optical path. A technician went to the NTT to check. The problem was solved, we started observing the first target with about 30 min delay.
