Abstract

The coronal mass ejection (CME) event of 1980 April 17 was observed with the SMM coronagraph, and an accompanying Type II (shock wave related) burst was observed simultaneously with the Culgoora and Clark Lake radioheliographs. The method of analysis of the combined radio observations is presented. Although the radio positions were affected by severe ionospheric refraction, the combined radio observations allow a useful reduction in the range of possible positions of the 80 MHz source when the 43 MHz source is required to lie within the range of position angles of the CME. The positions of the 80 MHz radio sources under this assumption are compared with the positions of the CME loop.
