Infrared brightness from the upper atmosphere of Uranus 2 (IMAGE)
Caption
Measured infrared brightness from the upper atmosphere of Uranus combined with rings of magnetic field lines which occur as the planet rotations (which produces the oval shape we see in most aurora). These rings are called shells and we expect the majority of auroral signal to occur between the dashed and dotted lines (as seen in 1986), which a portion of our results do.
