The magnitude of the polarization of 516,229 inclusively produced $$\Sigma^-$$'s has been measured to be 15.5±3.6%. The $$\Sigma^-$$'s were produced by 400 GeV/c protons on Be at angles of $$\pm$$7.5 mr with respect to the incident proton direction and had momenta between 120 and 290 GeV/c, with a mean momentum of 176 GeV/c. The polarization was measured from the asymmetry in the decay $$\Sigma^- \eta + \pi^-$$ The $$\Sigma^-$$ magnetic moment was also determined to be -0.89 $$\pm$$ 0.l4 $$\mu_N$$ corresponding to an anomalous precession angle of 11$$^{\circ}$$+15°.
