Abstract
Observations of a type II burst with fundamental and harmonic structure were made, with the Clark Lake Radio Observatory's E-W and N-S sweep frequency interferometers operating in the range 120–20 MHz with time and frequency resolution of 1 s and 100 kHz, respectively. The type II burst was preceded by a type III-type V, and the associated flare of importance SN was located at S 20 W 73. The interferometric data show that the fundamental and harmonic were coincident in position. Further, the type III positions as a function of frequency were practically the same as those of the type II burst. The implications of these results are discussed.
