  The largest anisotropy in the cosmic microwave background (CMB) is the
$\approx 3$ mK dipole assumed to be due to our velocity with respect to the
CMB. Over the past ten years the precision of our knowledge of the dipole has
increased by a factor of ten. We discuss the most recent measurement of this
dipole obtained from the four year COBE Differential Microwave Radiometers
(DMR) as reported by Lineweaver \etal (1996). The inferred velocity of the
Local Group is $v_{LG}= 627 \pm 22$ km/s in the direction $\ell = 276\deg \pm
3$, $b= 30\deg \pm 2$. We compare this most recent measurement to a compilation
of more than 30 years of dipole observations.
