  We review in these notes the status of the construction of the Pierre Auger
Observatory and present the first Physics results, based on the data collected
during the first year and a half of operation. These results are preliminary,
once the work to understand the systematics of the detectors are still
underway. We discuss the cosmic ray spectrum above 3 EeV, based on the
measurement done using the Surface Detector and the Fluorescence Detector,
both, components of the observatory. We discuss, as well, the search for
anisotropy near the Galactic Center and the limit on the photon fraction at the
highest energies.
