HD 143414 is shown to be a single-line binary with a 7.690-d orbit on the basis of extensive photoelectric photometry and photographic spectroscopy. The mass function, 0.007 solar mass, is low. This, it is noted, leads to a mass for the companion star of approximately 2.8 solar masses, assuming that the WN6 component has a mass of 40 solar masses and the orbital inclination is 60 deg. Its large displacement from the galactic plane (z = -744 pc) and its high peculiar radial velocity (-107 km/s in excess of differential galactic rotation) are seen as indicating that HD 143414 is a runaway. It is thought likely that this results from a recoil after a supernova explosion of the original primary; this would have occurred less than 5 million years ago near the galactic plane.
