    Hi Chris,

    When the Voyager 2 spacecraft flew by Uranus (in 1986) and Neptune(in 1989) auroral emissions were observed. However, they appeared to be weaker than the aurora observed on Jupiter and Saturn. We know more about the aurora on Jupiter and Saturn because more spacecraft have visited these planets than have visited Neptune and Uranus.
