Observations by the Ulysses Unified Radio and Plasma Wave instrument show that the most intense portion of the Jovian continuum emission appears to emanate from the planet's bow shock or magnetosheath region. This intense component is highly correlated with the Jovian “type III” or quasi‐periodic (QP‐15 and QP‐40) bursts. I suggest that this intense continuum component may be the unresolved merging of the low‐frequency portion of the QP bursts and occasionally the low‐frequency extent of broadband kilometric emissions which have been scattered and dispersed in the magnetosheath. A similar, but much less dramatic, effect happens at Earth with the scattering of LF bursts.
