(a) One of the ~1600 water Cherenkov stations that constitute the surface detector array of the Pierre Auger Observatory (forefront), and one of the four fluorescence buildings housing six of the 24 fluorescence telescopes (background). (b) Layout of the SD array with ~1600 water Cherenkov stations (depicted as dots), spread over a surface of ~3000 km2 (blue area), with a distance between stations of 1.5 km. The four fluorescence buildings at the edges of the observatory are also indicated.
