Relation of Jupiter's Radio Emission at Long Wavelengths to Solar Activity.

Since the spring of 1960 a strong positive correlation between Jupiter's decametric emission and solar decametric continuum emission observed at Boulder has been evident. The time delay of 1 to 2 days, with solar emission preceding Jupiter's emission, suggests that fast solar corpuscles, at velocities of the order of 0.1 c, are directly involved in the planet's atmosphere or magnetic field.
