Peculiarities of the anisotropy of cosmic rays with E 0 ≥ 1019 eV from Yakutsk EAS array data

Abstract

The arrival directions of primary cosmic ray particles with energies E0 ≥ 1019 eV and zenith angles θ ≤ 60° recorded on the Yakutsk array over the period 1974–2009 are analyzed. These events separated by different time intervals are shown to have different global anisotropies.
