An unprecedented view of Jupiter’s upper atmosphere and aurorae at visible wavelengths

Juno’s Extended Mission trajectory enables unprecedented high-resolution (~6-35 km scale) Stellar Reference Unit (SRU) limb imaging and aurora observations on Jupiter’s night side. The SRU is a low-light, broadband visible wavelength (450-1000 nm) star tracker, with a peak sensitivity from ~570-800 nm, that Juno utilizes as a multi-disciplinary science instrument. High altitude views of the atmosphere on Jupiter’s limb have been acquired in equatorial and high northern latitude regions, including within the auroral region. Our presentation will discuss Juno’s findings from this unique data set, including structural features observed from a few hundred to over a thousand km above the 1 bar level and their place within the interconnected inner Jovian system.
