The significant anisotropy in the arrival directions of the 69 events with\nenergy E> 55 EeV detected by Pierre Auger collaboration is located in the\n20-degree region centered near Cen A. Not only the 2-point, but also the\n3-point and 4-point autocorrelation functions are completely saturated by this\nregion. Besides there is an deficit of events in the direction of Virgo\ncluster. If one assumes that the excess around Cen A is due to heavy nuclei\nshifted from Virgo, one can explain 20-degree scale of this anomaly. Also\nlocation of the highest energy event between the Cen A region and the Virgo\ncluster supports this idea. Magnitude and direction of the magnetic field is\nsimilar in this case to those expected for Galactic models. The existence of\nnuclei sources in the sky opens the road for a self-consistent description of\nAuger data.\n
