EFOSC2 Calibrations: due to some problems these calibrations have been postponed to the morning.

Weather:
Start: humidity 54.0%, wind 5.9 m/s, seeing 1.5
Middle: humidity 48.0%, wind 3.6 m/s, seeing 0.9
End: humidity 40.0%, wind 6.0 m/s, seeing 0.79

Comments:
  • Cloudy night with brief dispersion periods.
  • Rotator position set to 120 to observe AM 0702-601N at J.
  • Sn2021ckj was observed at BVRI with the OB for faint objects instead of faintest by mistake. Even though the magnitude slightly above the range for the faint OB, the seeing was bellow 1, and since re-doing would imply changing the whole schedule on the fly, we settled on keeping this OB.
  • Due to some cumulative tiny delays between OBs, we decided to not do the classification of AT2021cvd as it was the OB at lower altitude through the night.
  • Unstable connection with loem through-out most of the night.
