To investigate energy ordering effects close to the most energetic cosmic rays, a measurement of EnergyEnergy-Correlations (EEC) has been performed with the data of the surface detector of the Pierre Auger observatory. The measurement includes the ultra high energy cosmic rays (UHECRs) with energies above E=5 EeV arriving within a small solid angular region around UHECRs with E > 60 EeV. The measured EEC distribution is compared to the expectation for isotropic arrival directions of UHECRs
