Observers: Pierre-François Léget, Nicolas Chotard & Marine Ducrot TAT: Nancy Elias-Rosa, Joe Polshaw, Stefan Taubenberger Sparse clouds in many directions at the begining of the night, so probably a non-photometric night. Cleared out quite fast after sunset. ---- CALIBRATIONS: - 19:00UT: In the control room. It is couldy for now. We are preparing the list of targets for tonight. - 20:20UT: 1x PESSTO_calib - 23:45UT: Sunset - 00:25UT: The lamp has been changed, calibration (arcs) are being done. - 00:35UT: Calibration is finished, we will do the 1x PESSTO_bias at the end of the night and are skipping the grz sky flat that we do/did not use/d.
