AT HIGH MASS ACCRETION RATES ACCRETION DISKS ARE EXPECTED TO BE SIGNIFICANTLY DIFFERENT FROM THE STANDARD OPTICALLY THICK GEOMETRICALLY THIN DISK. HOWEVER OBSERVATIONAL TESTS OF DISK STRUCTURE ARE RARE. EMISSION LINE REVERBERATION MAPPING HAS REVEALED THAT THE BROAD LINE REGION IN SUPER-EDDINGTON AGN ARE QUITE DIFFERENT BUT WHAT ABOUT THE DISK? THE ACCRETION DISK REVERBERATION MAPPING TECHNIQUE PROVIDES A WAY TO OBSERVATIONALLY TEST THE STRUCTURE OF THE ACCRETION DISK AT HIGH ACCRETION RATES. THROUGH FLEXIBLE AND HIGH-CADENCE MONITORING SWIFT HAS REVOLUTIONIZED ACCRETION DISK REVERBERATION OVER THE LAST FEW YEARS. HERE WE PROPOSE TO APPLY THIS TECHNIQUE TO A SUPER-EDDINGTON AGN FOR THE FIRST TIME TO EXPLORE THE STRUCTURE OF DISKS AT EXTREME MASS ACCRETION RATES.
