  Two EAS arrays during a day have recorded 3 particles with energies above 30
EeV arriving from the same sky region. Two events were registered by the
Yakutsk array and one - by the Telescope Array. Two Yakutsk events were
estimated to be same energy and the Telescope Array shower's energy was almost
2 times higher. This indicates the same magnetic rigidity of all three
particles, if the charge differs by a factor of 2. The relatively short
sequence of all three events and their "monochromaticity" in rigidity can be
due to the magnetic separation of particles in the acceleration process and
propagation of the beam.
