The Pierre Auger Observatory is a detector for cosmic rays that
makes special
emphasis on the study of primaries with energies greater than
1019 eV. It consists of
1600 water tanks covering a surface of 3000 km2 and fluorescence
detectors located in
4 stations overlooking that area which take data in coincidence
with the tanks on
clear moonless nights.
This hybrid arrangement allows a determination of the energy and
incidence angles of
each cosmic ray with small systematic errors. Data has been
gathered steadily for the
last years while the detector components were being installed.
Results on the
spectrum, composition, high energy photon and neutrino flux
limits and anisotropy of
cosmic rays with energy in excess of 1019 eV will be presented.
