Characterizing Jupiter’s Auroral Acceleration Region

Abstract: At Jupiter and other magnetized planets, auroral emissions are signatures of particle acceleration above the planetary atmosphere. Juno is currently exploring
Jupiter’s auroral acceleration region; however its low altitude coverage is limited to the dusk side of the magnetosphere. We use HST images of Jupiter’s aurora using the Knight Relation and Bayesian analysis to infer the characteristics of Jupiter’s auroral
acceleration region i.e. initial energy and density of precipitating electrons, and the
location of acceleration region. We will compare our findings to Juno’s initial results.
