The cosmic microwave background (CMB) dipole anisotropy (DA) (Lubin and Villela, this volume) implies a Local Group (LG) velocity v D = 640 ± 50Km s -1 relative to the comoving reference frame, in a direction which is 45° away from the Virgo cluster. The CMBDA seems to be consistent both in amplitude and in direction with the DA of the Hubble flow (780 ± 188km s -1) measured by Aaronson et al. (1985) in a set of 10 clusters at a distances 40 → 100 h -1 Mpc. Also, the IRAS point source catalogue exhibit a DA in the galaxy distribution in reasonable agreement in direction with the CMBDA (Yahil et al., 1985; Meiksin and Davis, 1985).
