Summary:Maps of the quiet solar corona, obtained at meter and decimeter wavelengths with the Nançay (France) Radioheliograph, are compared to Yohkoh soft X-ray images in order to study large scale density structures of the corona. Of particular interest is a global restructuring of the corona, observed on 19 May 1992 in X-rays, in conjunction with a coronal mass ejection. The radio observations show the CME moving continuum, while the Yohkoh images show the slower motion of the X-ray loops. After this event the appearance of a new noise storm, with a duration of several days, was observed.
