Juno UVS maps from Perijove 3 display the brightness (A) and color ratio (C) of the emissions from Juno’s polar orbit vantage point taken (from supp. in Greathouse et al. 2021). The wire frame model in the center shows the view of Jupiter from JUICE during the high inclination phase and the orientation of the aurora and terminator for the time of the UVS observations (aurora on the night side). Even from a much greater distance, JUICE UVS simulations of the same observation from Juno now displayed in B and D will allow for detailed study of the auroral night side emissions unobservable by Earth-orbiting observatories
