  We examine the radiative $\Delta \to \gamma N$ transition at the real photon
point $Q^2=0$ using the framework of light-cone QCD sum rules. In particular,
the sum rules for the transition form factors $G_M(0)$ and $R_{EM}$ are
determined up to twist 4. The result for $G_M(0)$ agrees with experiment within
10% accuracy. The agreement for $R_{EM}$ is also reasonable. In addition, we
derive new light-cone sum rules for the magnetic moments of nucleons, with a
complete account of twist-4 corrections based on a recent reanalysis of photon
distribution amplitudes.
