Calibrations:
EFOSC daytime calibrations (biases, flats and arcs) Sky flats grz (evening)
Weather:
Start: Humidity 30%, wind speed 2 m/s, seeing: 1.2".
Middle: Humidity 30%, wind speed 3m/s , seeing: 0.7"
End : Humidity 30%, wind speed 5m/s, seeing: 0.9"
Comments: seeing started slightly variable but then got pretty stable. moon precludes most important follow-up observations as well as standard star early in the night.
