Abstract The reaction gamma p -> K-S(0)Sigma(+) is studied in the photon energy range from threshold. Linearly polarised photon beams from coherent bremsstrahlung enabled the first measurement of photon beam asymmetries in this reaction up to E-gamma = 1650 MeV. In addition, the recoil hyperon polarisation was determined through the asymmetry in the weak decay Sigma(+) -> p pi(0) up to E-gamma = 2250 MeV. The data are compared to partial wave analyses, and the possible impact on the interpretation of a recently observed prominent structure in the cross section near the K* thresholds is discussed.
