Reconnection- and Dipolarization-Driven Auroral Dawn Storms and Injections
Bonfond, B.; Vogt, M. F.; Mauk, B. H. +8 more
Jupiter displays many distinct auroral structures, among which auroral dawn storms and auroral injections are often observed contemporaneously. However, it is unclear if the contemporaneous nature of the observations is a coincidence or part of an underlying physical connection. We show six clear examples from a recent Hubble Space Telescope campa…
Comparisons Between Jupiter's X-ray, UV and Radio Emissions and In-Situ Solar Wind Measurements During 2007
Jackman, C. M.; Lamy, L.; Branduardi-Raymont, G. +21 more
We compare Chandra and XMM-Newton X-ray observations of Jupiter during 2007 with a rich multi-instrument data set including upstream in situ solar wind measurements from the New Horizons spacecraft, radio emissions from the Nançay Decametric Array and Wind/Waves, and ultraviolet (UV) observations from the Hubble Space Telescope. New Horizons data …
Temporal and Spectral Studies by XMM-Newton of Jupiter's X-ray Auroras During a Compression Event
Coates, A. J.; Jackman, C. M.; Branduardi-Raymont, G. +16 more
We report the temporal and spectral results of the first XMM-Newton observation of Jupiter's X-ray auroras during a clear magnetospheric compression event on June 2017 as confirmed by data from the Jovian Auroral Distributions Experiment (JADE) instrument onboard Juno. The northern and southern auroras were visible twice and thrice respectively as…
An Enhancement of Jupiter's Main Auroral Emission and Magnetospheric Currents
Wilson, R. J.; Kurth, W. S.; Bagenal, F. +9 more
We present observations of Jupiter's magnetic field and plasma obtained with the NASA Juno spacecraft during February 2018, along with simultaneous Hubble Space Telescope (HST) observations of the planet's auroras. We show that a few-day transient enhancement of the azimuthal and radial magnetic fields and plasma temperature was coincident with a …
