SCIENCE GOALS AND OBJECTIVES THE GOAL OF THE PROPOSED WORK IS TO QUANTIFY HOW MAGNETOSPHERE-IONOSPHERE COUPLING AT JUPITER IS AFFECTED BY 1) LOCAL TIME ASYMMETRIES IN THE MAGNETOSPHERE AND 2) TEMPORAL VARIABILITY RELATED TO THE INTERNAL MASS LOADING FROM IO AND EXTERNAL FORCING FROM THE SOLAR WIND. IN ORDER TO ACHIEVE THIS GOAL WE WILL COMBINE DATA ANALYSIS FROM THE GALILEO SPACECRAFT AND THE HUBBLE SPACE TELESCOPE WITH COMPUTATIONAL MODELS. THE RESULTS OF THIS WORK WILL IMPROVE OUR UNDERSTANDING OF SPATIAL AND TEMPORAL VARIABILITY IN THE BRIGHTNESS AND LOCATION OF JUPITER S MAIN EMISSION WHICH HAS IMPLICATIONS FOR MAGNETOSPHERE-IONOSPHERE COUPLING IN OTHER ROTATION-DOMINATED PLANETARY SYSTEMS.
