The Be star LSI +61303 shows the 1584 d period in its X-ray emission. The difference in the 1584 d period phases of the peak X-ray and radio emissions and the Hα emission is explained as being due to the time taken by the density enhancement, emitted by the Be star, and which is responsible for the increased emissions, to reach the periastron of the orbit of the binary companion.
