Abstract
This paper summarizes the status and the recent measurements of the Pierre Auger Observatory. The energy spectrum is described and its features discussed. Searches for anisotropy of cosmic ray arrival directions on large scales and through correlation with catalogues of celestial objects are reported. The first measurement of the proton-air cross section around 1018 eV is discussed. The mass composition is addressed with measurements of the variation of the depth of shower maximum with energy and with muon density at the ground. An update on the searches for neutrinos and photons is also presented. [ABSTRACT FROM AUTHOR]
