  Arrival directions of 63 extensive air showers with energies
4*10^19<E<=3*10^20 eV detected by the AGASA, Yakutsk, Haverah Park arrays are
analyzed in order to identify possible sources of cosmic rays with these
energies. We searched for active galactic nuclei within error boxes around the
shower-arrival directions and calculated the probabilities of objects being in
the error boxes by chance. Our previous result obtained in 1996-2001 (see
references in the text) is confirmed: the probabilities are small, P>3 sigma
(sigma is the parameter of Gaussian distribution) for Seyfert galaxies with
redshifts z<0.01 (along with BL Lacertae objects). The Seyfert galaxies are
characterized by moderate luminosities (L<10^46 erg/s) and weak radio and X-ray
emission.
