Aurora on Ganymede

Jupiter’s largest satellite Ganymede exhibits classic auroral emission, including a well defined auroral oval. Auroral emissions have been imaged both from the Keck telescope at visible wavelengths, and from the Hubble Space Telescope in the ultraviolet. The sparse number of observations to date show fascinating, and seemingly irreconcilable, features. This talk will summarize the existing imaging observations, as well as the modeling work done to date, which is based on the in situ magenetic field measurements made by the Galileo spacecraft.
