  We report our attempts to detect and confirm a narrow moving component in the
H-alpha emission line of the radio emitting Be/X-ray binary LSI+61 303 (V615
Cas, GT0236+610). 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 H-alpha emitting disk.
