Wobbling of the Jovian magnetic equator (red circle) on the plane of the sky during one planetary rotation. The rings (in black) lie in the rotational equator. The blue line represents the main axis of the projection on the sky of the magnetic equator, which should also be the main axis of the radiation belt’s image as a function of time or longitude. Observer’s longitude (CML) is indicated in each panel, along with the reference meridian (in red).
