Enhanced mid-infrared emission from CH4 and other stratospheric hydrocarbons has been
observed coincident with Jupiter's ultraviolet auroral emission,–. This suggests that auroral
processes and the neutral stratosphere of Jupiter are coupled; however, the exact nature of
this coupling is unknown. Here we present a time series of Subaru-COMICS images of
Jupiter measured at a wavelength of 7.80 μm on 11–14 January, 4–5 February and 17–20
May 2017. These data show that both the morphology and magnitude of the auroral CH4 …
