Calibrations:
EFOSC2:
bias, specflats and arcs (afternoon)
skyflats in gri (evening twilight) skyflats in zirg (morning twilight)
Weather: Start: Humidity 41%, wind speed 1.4 m/s, seeing: 0.9"
Middle: Humidity 38%, wind speed 1.5 m/s , seeing 1.0":
End : Humidity 32%, wind speed 5 m/s, seeing: 1.1 "
Comments: Night started off with some amazing desserts... And then only got better - (sub-)arcsecond seeing and photometric conditions.
