We have discussed the annual peculiarity of the phase differences of the Omega of 10 pairs. The phase differences were observed continuously from Feb. 1, 1974 (A-D pair), from Jan. 1, 1975 (A-C and C-D), from Jan. 1, 1976 (A-H, C-H and D-H) and from Jan. 1, 1977 (A-E, C-E, D-E and E-H) until Dec. 31, 1978 at the Faculty of Fisheries of Hokkaido University. In this paper we deal with the reappearance of these phase differences. The standard deviations around mean values are indicated in Fig. 1〜10 and Table 2 and the amplitudes α_n and phase β_n obtained from the following equation PPC=α_0+Σ^^<12>__<N=1>α_n sin (nθ+β_n) (θ : U.T.) are indicated in Fig. 11〜30. The relation between the daytime standard deviation and the night-time are indicated in Table 3, 4. As a result, except A and D station reappearance on the C-D, C-H and E-H pairs are better than other pairs and when both the receiver and the transmitter are used in the daytime, very good reappearances are found.
