Scientific paper

Five ultrahigh energy cosmic rays in the combined AGASA and HiRes stereo data are analyzed to test whether they come from a single source. The quad above 37 EeV in the 94-event high energy dataset can be analyzed without considering magnetic dispersion. The probability that it is a chance association is 10^-3. Assuming the source is continuous, the random magnetic deflections these UHECRs accumulated en route from their source can be used to estimate \sqrt{B^2 \lambda D} ~ 1 nG-Mpc. A quintuplet including a HiRes event between 10 and 30 EeV is well fit with this value. Galactic magnetic deflection appears to be smaller than in some models.
