| Abstract | The combination of in-situ measurements from the Juno spacecraft and remoteX-ray observations have provided tantalising clues towards the processes thatpermit rapidly-rotating magnetised bodies to produce X-ray aurora. Since Junodoes not carry an X-ray instrument, AO 18 presents unique opportunities whichmay definitively identify the acceleration process/es that allow Jupiter toproduce X-ray aurorae. We will\:1. Identify whether magnetic unloading triggersthe X-ray aurora by testing for correlations between X-ray auroral emissions andsimultaneous Juno measurements of the plasma sheet. 2. Identify and quantify theauroral acceleration process/es at Jupiter by testing for correlations betweenX-ray spectral fluxes and in-situ electron and ion fluxes and multi-waveband observations. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
