We consider the asymmetry in the decay $\Omega^-\rightarrow\Xi^-\gamma$assuming that a Vector Meson Dominance approach for the $s\rightarrow d\gamma$transition gives the dominant contribution. Since in this long-distanceapproximation the decay is due to a single quark transition $s\rightarrowd\gamma$, the angular distribution asymmetry is given by the single positiveasymmetry parameter $\alpha_h = \frac{M^2_s-M^2_d}{M^2_s+M^2_d} = 0.4\pm0.1$.We also discuss the asymmetry in $\Xi \rightarrow \Sigma^-\gamma$, which isexpected to be between -0.2 and 0.3.Comment: 16 pages,no figures,Late
