'''Dipole anisotropy''' is a form of [[anisotropy]] and the progressive difference in the [[frequency]] of [[radiation]] from opposite directions due to the motion of the observer relative to the source. As a result of that motion, one end of the 360-degree spectrum is [[doppler effect|redshifted]], whereas the other end is [[doppler effect|blueshifted]]. That effect is notable in measurements of the [[cosmic microwave background radiation]], due to the motion of [[earth]].
