Microwave and Hard X ray Imaging of Energetic Electrons in Solar Flares: Event of 2003 June 17

We discuss a large flare that was observed simultaneously by RHESSI in hard X-rays and by the Nobeyama Radio Heliograph (NoRH) in microwaves. The imaging observations made both by RHESSI and NoRH show many interesting features which may be relevant for producing realistic flare models.
