From the CMB data, it is seen that the Sun appears to be moving at 369.82 ± 0.11 km/s relative to the reference frame of the CMB (also called the CMB rest frame, or the frame of reference in which there is no motion through the CMB). The Local Group — the galaxy group that includes our own Milky Way galaxy — appears to be moving at 620 ± 15 km/s in the direction of galactic longitude ℓ = 271.9° ± 2°, b = 30° ± 3°. The dipole is now used to calibrate mapping studies.
