We report on the observations of cosmic rays with energies > 1.0 EeV from Jan 2004 to April 2009 by the Pierre Auger Observatory. During this period the Observatory has grown from about 300 surface detectors to about 1600 upon its completion in November 2008. The 1600 surface detectors are overlooked by 24 fluorescence telescopes. We report on measurements of the cosmic ray spectrum, the arrival directions and the elongation rate. We also report limits for the photon and neutrino components of this cosmic radiation.
