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

- 23:50UT: There has a been problem with Helium lamp during the calibration procedure, and they had to change it,

- 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.
