  The possibility that the cosmic variance outliers present in the recently
released WMAP multipole moments are due to oscillations in the primordial power
spectrum is investigated. Since the most important contribution to the WMAP
likelihood originates from the outliers at relatively small angular scale
(around the first Doppler peak), special attention is paid to these in contrast
with previous studies on the subject which have concentrated on the large
scales outliers only (i.e. the quadrupole and octupole). As a physically
motivated example, the case where the oscillations are of trans-Planckian
origin is considered. It is shown that the presence of the oscillations causes
an important drop in the WMAP chi square of about fifteen. The F-test reveals
that such a drop has a probability less than 0.06% to occur by chance and can
therefore be considered as statistically significant.
