afternoon CALIBRATIONS

EFOSC2 bias                                           avg~210, std~10, no pattern

EFOSC2 Spectroscopic flats and arcs

OBSERVATIONS: start regularly at twilight

EFOSC2 Skyflats UVi                               ok

Target                       Type             UT         Filter/Grism      Slit            Seeing    Grade (A/B/C)     Comments

at beginning image analysis fails because seeing too bad (1.9")
