Some of the occulted flares observed by RHESSI (on 16/04/02 and 04/08/02) were also observed at metric/decimetric wavelengths by the Nançay Radioheliograph (NRH) which provided images of the radio emission produced in the solar corona at five frequencies in the 150-450 MHz range. We started to work on some comparisons of the time evolutions of the X-ray images observed in different energy bands by RHESSI and of the time evolutions of the radio emission sites at the five frequencies observed by the NRH to investigate the possible link between the coronal hard X-ray emissions and the production of non-thermal radio emitting electrons.
