Abstract An attempt has been made to find the sources of cosmic rays using the Utah Fly's Eye detector; no statistically significant departure from isotropy has been observed for energies greater than 0.4 EeV, where 1 EeV is equal to 10 to the 18th eV. If a significant fraction of the observed cosmic rays are Galactic Fe, or 'universal' extragalactic protons, then the observed uniformity of arrival directions would be reasonable. The present isotropic results favor a universal extragalactic source.
