A search for a 78.4 day modulation in the high energy X-ray flux
observed with OSO-8 and in the U-band optical polarization is reported.
It is suggested that if such a modulation does exist, it is more likely
to be related to the rotation of the free modes of oscillation of the
primary than to the existence of a third body in the system.
