Comparison of the surface reflectance map in the [140 nm, 150 nm] interval with two different datasets. Top: comparison with the visible surface map of Ganymede, highlighting geological features. Bottom: comparison with the total brightness map of the atomic oxygen auroral emission lines at 130.4 nm and 135.6 nm, observed during the Juno PJ34 flyby. The dashed magenta polygons indicate the main auroral regions identified from the UVS observations.
