Night Report 2018-02-14

Observers: Jesse T. Palmerio, Ken W. Smith,
Support Team: David O'Neill, Owen McBrien, Peter Clark, Erkki Kankare
TAT:  Cristina Barbarino, Morgan Fraser
TO: Mauricio Martinez (day) Eduardo Matamoros (night)

Calibrations: EFOSC2 PESSTO_calib, PESSTO_bias
Sky flats: g band sky flats in the evening

Weather: Thin, some clouds, sky with humidity 55%, variable seeing (0.8"-1.5").

Comments: Some difficulty in setting up the SOFI observations. One of the CCD quadrants had a gain problem. Wrong telluric for one object.
