Search for anisotropies in the ultra high energy cosmic rays with the Pierre Auger Observatory

We present in these proceedings a method developped by the Pierre Auger Collaboration to estimate the background expected number of events in a given direction of the sky in the purpose of anisotropy searches. We also present the first results of the Pierre Auger Observatory regarding the search for excess sources in the regions previously announced for prescriptions, a blind search and a study towards the Galactic Center and Galactic and Super Galactic planes.
