Glushkov, M. Pravdin] Results of a harmonic analysis of the arrival directions for primary cosmic-ray particles with energies E 0 ⩾ 1017 eV and zenith angles θ ⩽ 45° recorded on the Yakutsk array over 29 years of its continuous operation (1983-2012) are presented. These events are shown to have different global anisotropies in different time intervals: the phase of the first harmonic φ 1 = 119° ± 18° and its amplitude A 1 = 0.030 ± 0.014 in the 1983-1994 samples changed into φ 1 = 284° ± 13° and A 1 = 0.033 ± 0.010 in 1998-2010. All of this could be caused by a considerably increased flux of heavy nuclei from the exit of the Galaxy's local arm after 1996.
