Scientific paper

A type II solar radio burst, which was observed by the satellite IMP-6 and reported by Malitson et al. (1973), is correlated with a type II burst recorded by ground-based instruments at Culgoora. Since no other important coronal activity (as measured by meter-wave observations) occurred in the 9 hr preceding the onset of the type II burst at IMP-6, this association is preferred as an alternative to the nonexplosive flare source suggested by Malitson et al. A discrepancy is revealed by trying to fit both sets of observations to a typical plasma density profile. The interpretation favored is that an expanding shock wave interacted with two different plasma structures (possibly streamers) which produced the radio emission recorded by the two instruments respectively. In this case it is not meaningful to compare shock speeds deduced at different distances from the sun, although future observations of this nature may be a useful tool for investigating shock deceleration at distances greater than about 50 solar radii.
