| Abstract: | The Cassini imaging science subsystem observed Europa in eclipse during Cassini‘s Jupiter flyby. The disk-resolved observations revealed a spatially nonuniform emission in the wavelength range of 200-1050 nm (clear filters). By building on observations and simulations of Europa‘s Na atmosphere and torus we find that electron-excited Na in Europa‘s tenuous atmosphere can account for the observed emission if the Na is ejected preferentially from Europa‘s dark terrain.
