Relativistic runaway electrons (REs) generated during plasma disruptions have the potential to severely damage future fusion devices. In order to avoid and properly mitigate REs, it is important to understand their evolution in both momentum and real space. We present a first look at the real space distribution of runaway electrons in Alcator C-Mod. Visible RE synchrotron emission, resulting from high magnetic fields, is measured by distortion-corrected visible cameras. These images are compared with the new synthetic diagnostic SOFT (Synchrotron-detecting Orbit-Following Toolkit) coupled with kinetic solver CODE (COllisional Distribution of Electrons). Initial results show good agreement between experiment and simulation.
