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