  COMPASS is a fixed target experiment presently running at CERN. In 2002,
2003, and 2004 the experiment used a 160 GeV polarized muon beam coming from
SPS and scattered off a $^6$LiD target. The nucleons in the target can be
polarized either longitudinally or transversely with respect to the muon beam
and 20% of the running time has been devoted to transverse polarization. From
the transverse polarization data collected in 2002, which correspond to a total
integrated luminosity of about 200 pb$^{-1}$, the Collins and the Sivers
asymmetries have been determined separately and the preliminary results are
presented here.
