Chajnantor Surveillance Camera

Every two hours, a surveillance camera takes an image of the ALMA site near Cerro Chajnantor. The camera, installed on 1997 June 15, faces southwest. It views a calibration target, 10.2 m away, and a weather station behind that.


Calibration Target

The large squares are 10 cm (4 in) and the small squares are 2.5 cm (1 in).
