Jupiter has pretty impressive auroras as Juno can attest. This particular aurora in Jupiter’s north is not from the recent solar flare responsible for ours. The CME associated with our current storm occurred on 04 September and arrived here late yesterday, so it has a ways to go before it gets to Jupiter – about 4 more AU.
This particular view is from Juno’s it was taken by Juno’s Ultraviolet Imaging Spectrometer (UVS) instrument on 11 December 2016 which also explains why Jupiter is not visible.
This could be just me, but the aurora looks sort of happy to be there.
