observatory. The southern site, in Malarguee, Mendoza, Argentia, covers
3000 km^2, instrumented with more than 1600 water Cherenkov detectors and
24 fluorescence telescopes.
I will present the status of the Pierre Auger Observatory and its recent
results. Even though the obesravtory was designed primarily as a detector
for charged cosmic rays, was clear from the beginning that it can also
identify photons and neutrinos. I will discuss the methods for the
identification of the primary cosmic rays, with emphasis on neutrino
tagging, and present the flux limits obtained.
