These include measurements of the spectrum, anisotropies and composition of ultra-high energy cosmic rays. The ankle of the spectrum is measured at $4\\times 10^{18}$~eV and a suppression above $3\\times 10^{19}$~eV consistent with the GZK effect is observed. At energies above $5.5\\times 10^{19}$~eV a correlation with the distribution of nearby extragalactic objects is found, including an excess around the direction of Centaurus~A, the nearest radio loud active galaxy.
