Short summary
Early models of the main auroral emission at Jupiter assumed axisymmetry, but significant local time variability is obvious on any image of the Jovian aurorae. Here we use Far-UV images from the Hubble Space Telescope to further characterise these variations on a statistical basis. We show that the dusk side sector is ~3 times brighter than the dawn side and we suggest that such an asymmetry could be the result of a partial ring current in the night side magnetosphere.
