EIT 195 Å and NRH data of the 2000 March 2 event. The top-left panel shows a pre-event image while the other panels are base difference images (the pre-event image was subtracted from each other image). The panel on the right of the left-bottom panel shows contour plots of the type II source at 236 and 164 MHz obtained by the NRH at 13:41:09 and 13:41:26 UT, respectively (contour levels at 65% and 85% of each frequency’s maximum). The panel on the left of the right-bottom panel shows the centroids of all NRH sources associated with the type II burst (white stars for 236 MHz and black triangles for 164 MHz). The arrow denotes the overall direction of motion of the type II radio source at each frequency.
