The transition magnetic moments for decuplet-to-octet baryon electromagnetic decays are calculated from the CLAS experimental results and are compared with calculations to first order in the 1/N_c expansion of quantum chromodynamics (QCD) and new U-spin predictions. Using the U-spin predictions for the Σ^*0→Σ⁰γ and Σ^*+ → Σ⁺γ decays, the SU(3)-forbidden transitionΣ^*- → Σ^-γ is obtained. In addition, the doubly strange baryon radiative decay $${\Xi}$$^*0 → $${\Xi}$$γ is predicted using U-spin.
