The Infrared Auroral Footprint Tracks of Io, Europa and Ganymede at Jupiter Observed by Juno-JIRAM
Altieri, F.; Sindoni, G.; Piccioni, G. +20 more
The electromagnetic coupling between the Galilean satellites at Jupiter and the planetary ionosphere generates an auroral footprint, which is detected with high spatial resolution in the infrared L band by the Jovian InfraRed Auroral Mapper (JIRAM) onboard the Juno spacecraft. We report the JIRAM data acquired since 27 August 2016 until 23 May 202…
On the Global Features of the 10-60-Min ULF Waves in Jovian Magnetosphere: Juno Observations
Bonfond, B.; Xu, Y.; Fu, S. Y. +8 more
In the Jovian magnetosphere, quasi-periodic phenomena, with quasi-periods on the order of 10-60 min, are frequently identified using different data sets. These pulsations are a branch of ultra-low frequency (ULF) waves, which are believed to play a crucial role in driving the energy circulation within Jupiter's magnetosphere. In this study, we uti…
The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI
de Pater, Imke; Wong, Michael H.; Fletcher, Leigh N. +15 more
Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid-Infrared Instrument (4.9-27.9 µm) in July and August 2022. These observations took place alongside a suite of visual and infrared observations from; Hubble, JWST/NIRCam, Very Large Telescope/VISIR and amateur observers which provided both spatial and tempo…
