We present results from a model of oxygen isotopic anomaly production through selective photodissociation of CO within the collapsing proto-solar cloud. Our model produces a proto-Sun with a wide range of Delta O-17 values depending, on the intensity of the ultraviolet radiation field. Dramatically different results from two recent solar wind oxygen isotope Measurements indicate that a variety of compositions remain possible for the solar oxygen isotope composition. However constrained by other measurements from comets and meteorites. our models imply the birth of the Sun in a stellar cluster with all enhanced radiation field and are therefore consistent with a supernova source for Fe-60 in meteorites.
