Rotation-averaged images in total intensity of Jupiter’s synchrotron radiation in P band (left-hand panels) and L band (right-hand panels) for periods when D_E was ~3.5° and the VLA was in the A-array configuration. Radio maps at the same wavelength were degraded to the same image resolution. The planet disk was added to highlight the spatial distribution of the radiation around Jupiter. The main features of Jupiter’s synchrotron radiation are displayed in all four radio maps: a primary source of radiation near the equator and secondary sources at high latitudes appear on either or both sides of the planet. Overall, the brightness distributions in mid-December 1988 are more east-west asymmetric and confined to the equator than they are in early January 2001.
