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.
