Response of Jupiter's auroras to conditions in the interplanetary medium as measured by the Hubble Space Telescope and Juno

Wilson, R. J.; Kurth, W. S.; McComas, D. J. +24 more

We present the first comparison of Jupiter's auroral morphology with an extended, continuous, and complete set of near-Jupiter interplanetary data, revealing the response of Jupiter's auroras to the interplanetary conditions. We show that for ∼1-3 days following compression region onset, the planet's main emission brightened. A duskside poleward r…

Transient brightening of Jupiter's aurora observed by the Hisaki satellite and Hubble Space Telescope during approach phase of the Juno spacecraft

Fujimoto, M.; Yoshioka, K.; Gray, R. L. +11 more

In early 2014, continuous monitoring with the Hisaki satellite discovered transient auroral emission at Jupiter during a period when the solar wind was relatively quiet for a few days. Simultaneous imaging made by the Hubble Space Telescope (HST) suggested that the transient aurora is associated with a global magnetospheric disturbance that spans …

Jupiter cloud morphology and zonal winds from ground-based observations before and during Juno's first perijove

Hueso, R.; Sánchez-Lavega, A.; Rojas, J. F. +8 more

We analyze Jupiter observations between December 2015 and August 2016 in the 0.38-1.7 µm wavelength range from the PlanetCam instrument at the 2.2 m telescope at Calar Alto Observatory and in the optical range by amateur observers contributing to the Planetary Virtual Observatory Laboratory. Over this time Jupiter was in a quiescent state wi…
