We report our attempts to detect and confirm a narrow moving component in the Hα emission line of LS I+61°303. The existence of this spectral feature was already suspected in the past. As a result, we find that this component does exist and that its radial velocity varies in agreement with the radio period of the system. We interpret it tentatively as due to a denser region, or bulge, orbiting near the outer edge of the Hα emitting disk.
