Abstract
Previous analysis of arrival directions of ultrahigh energy cosmic rays (UHECR) confirmed the presence of clusters with arrival directions lying approx. 3°. The present work demonstrates that the observed clustering favors larger density of sources, provided the propagation of UHECR with energy E>1020 eV is not strongly affected by extragalactic magnetic fields.
