The Pc 5 periods in June, 1973, are revealed to be shorter than those in December, 1973. An eye-reading analysis of Pc 5's on the correlation chart obtained at Syowa Station from 1974 to 1977 shows also such annual variation in which the June periods are shorter than the December periods. These annual variations are regarded to be non-seasonal, since all Pc 5 period at Byrd, Pc 4 period at Fredencksburg, and whistler dispersion at Stanford exhibited the same annual variation as that at Syowa Station independent on the local seasons of these stations.
