[en] While the Voyager spacecraft were undertaking their paradigm-shifting explorations of the Jovian system in 1979, the Einstein X-ray observatory was also taking the first X-ray images of Jupiter (Metzger et al. 1983). Two decades later, the launch of the Chandra and XMM-Newton NASA and ESA Flagship X-ray observatories ushered in the modern era of X-ray astronomy. These complementary astrophysics platforms uncovered a variety of vibrant and dynamic X-ray aurorae, the majority of which mapped to sources beyond 50 RJ . In this talk, through combined Hubble-Chandra, UV-X-ray auroral videos and XMM-Newton-Juno Waves time-series spectrograms we explore connections between these X-ray auroral emissions and what appear to be their UV and Radio counterparts. Exploring simultaneous Juno in-situ magnetic field and JEDI and JADE plasma data shows that the X-ray auroral pulsations share their pulsation rate with electromagnetic ion cyclotron waves, and anti-phase variations in the outer magnetosphere plasma and magnetic field data. The antiphase pulsations appear indicative of slow mode or mirror mode waves. We will speculate on how these shared multi-waveband periodicities may be causally linked, in an effort to unify connected auroral emissions and processes. Finally, having noted connections between the X-ray and UV, we show preliminary analysis of the first spatially resolved XUV (60–170 Angstrom) observation of Jupiter, acquired through a technique we helped pioneer on Chandra. This shows up to an order of magnitude count-rate increase over typical X-ray observations. We discuss and show models that seek to identify the source of these enhancements.
