  The observed CMBR dipole, generally interpreted as the consequence of the
peculiar motion of the Sun with respect to the reference frame of the CMBR, can
also be explained by the presence of ultra large scale (of the order of
$100H_0^{-1}$) isocurvature perturbations. Moreover, the simplest model of
inflation with several scalar fields, namely that of double inflation, with
appropriate parameters, can produce such perturbations.
