Night report page - 20121213

Observer: Laurent Le Guillou

Data reduction team: Sylvain Baumont, Yen-Chen Pan, Mark Sullivan.

Operators tried to fix several problems during the day: the electromechanical one with the azimuth axis, but also problems with shutter and filter wheels.

The plan was to observe with EFOSC2 for 1h30, then SOFI, then EFOSC2. But SOFI has a problem with its filter wheel, so only EFOSC2 was used during the night.

The target LSQ12hbx has clearly disappeared.
