Abstract
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 o
f double inflation, with appropriate parameters, can produce such pert
urbations.
