Magnetosphere-Ionosphere Coupling across Jupiter's main oval and satellite footprints: A multi-instrument study based on Juno's nominal mission

The dynamics of the Jovian magnetosphere is controlled by the complex interplay of the planet's fast rotation, its solar-wind interaction and its main plasma source at the Io torus, mediated by magnetosphere-ionosphere-thermosphere coupling processes. At the ionospheric level, these processes can be characterized by the distribution of ionospheric conductances, currents and electric fields, charged particles transport, auroral emissions and energy deposition into the thermosphere. A method based on Juno multi-instrument data (MAG, JADE, JEDI, UVS, JIRAM and WAVES) and modelling tools was first developed by Wang et al. (2021) to derive the distribution of these parameters across Jupiter's main ovals for Juno's first nine orbits. In this communication we apply this method to Juno's full nominal mission to study the current systems that flow across the northern and south main auroral ovals and their closure along magnetic field lines. The general trend of these current systems displays a significant interhemispheric asymmetry. We discuss the implications of this asyernmetry on our current understanding of the coupling of the Jovian magnetodisk to the two conjugate hemispheres. We also use this method to study current systems across some of the Galilean moons auroral tails.
