EIT 195 Å and NRH data of the 2000 March 7 event in the same format as in Fig. 3, with the following exceptions: all EIT images except the one of the top-left panel are running difference images. The bottom-left panel shows contour plots of the type II source at 236 and 164 MHz obtained by the NRH at 14:26:15 and 14:26:39 UT, respectively. The right-bottom panel shows the centroids of all NRH sources associated with the type II burst (white stars for 236 MHz, black triangles for 164 MHz sources of branch A, and gray diamonds for 164 MHz sources of branch B).
