Southern Hemisphere Observation of a $10^{18}$eV Cosmic Ray Near the Direction of the Galactic Centre

  • 4 September 2000
Abstract
We report on an analysis of data from the southern hemisphere SUGAR cosmic ray detector. We confirm the existence of an excess of $10^{18}$eV cosmic rays from a direction close to the Galactic Centre, first reported by the AGASA group. We find that the signal is consistent with that from a point source, and we find evidence for an excess of cosmic rays coming from the direction of the Galactic Centre itself.
