Abstract
Recently, a possible clustering of a subset of observed ultra-high ene rgy cosmic rays above similar or equal to 40 EeV (4 x 10(19) eV) in pa irs near the supergalactic plane was reported. We show that a confirma tion of this effect would provide information on the origin and nature of these events and, in case of charged primaries, imply interesting constraints on the extragalactic magnetic field. Possible implications for the most common models of ultra-high energy cosmic ray production in the literature are discussed.
