Abstract
Data collected by the Pierre Auger Observatory through 31 August 2007 showed evidence for anisotropy in the arrival directions of cosmic rays above the Greisen–Zatsepin–Kuz’min energy threshold, 6 × 10^19 eV. An updated measurement is reported here using the arrival directions of cosmic rays recorded above the same energy threshold through 31 December 2009.
