Λ∘ polarization in inclusive production by protons on iridium has been measured at 28.5 GeV/c over the region 0.55 GeV/c<~P⊥<~1.6 GeV/c. The polarization rises from (-12.6±5.5)% at 0.55 GeV/c to (-33.4±4.6)% at 1.6 GeV/c. Significant differences from previous measurements at other energies with different targets are observed, particularly at low P⊥.
