We present a case study of Jovian X-ray observations from a joint Chandra and XMM-Newton campaign on June 18th - 19th 2017. The 10-hour Chandra observation and 28-hour XMM-Newton observation overlapped by ~ 9 hours, allowing both spatial and spectral X-ray analysis of Jupiter in tandem. We showcase dynamic new X-ray auroral videos demonstrating the time-varying spatial morphology of the highest energy auroral emission over a 10 hour continuous observation. Alongside the X-ray auroral videos, we present light curves from Chandra; timing analysis of significant quasi-periodic oscillations detected in the north polar region and further discuss the morphology of the emission with new polar plots of the Chandra observations. In addition, we show spectra taken from XMM-Newton and frame the X-ray observations in the context of Juno in situ observations. During this X-ray observation interval Juno was near its apojove on the dawn flank, close to the expected nominal position of the magnetopause. Juno data can be used to infer the state of compression or expansion of the magnetosphere and to place these observations in context of possible magnetospheric drivers linked to boundary dynamics.
