Juno auroral observations and their surprising implications

The Juno spacecraft carries with it a suite of instruments for both in situ and remote sensing observations of Jupiter's aurora and its response to variations in the polar magnetosphere. Observations by the particle instruments (JEDI and JADE) measure the energetic electron and ion distributions locally at the spacecraft, while the magnetometer (MAG) provides the instantaneous magnitude and orientation of Jupiter's magnetic field. Spectral imagers (UVS and JIRAM) perform remote sensing of H_2 ultraviolet and H_3^+ near-infrared auroral emissions to give context for the particles and fields instruments to help untangle the complex processes occurring in Jupiter's giant magnetosphere. Antennas (Waves) perform remote sensing and in situ measurements of complex jovian auroral radio emissions. Here we will present important and surprising results from the many successful perijoves to date.
