Short summary
In the present paper diffuse auroral intensities of OI λ1356 Å emission have been calculated, resulting from pitch angle diffusion of magnetospheric electrons by whistler-mode waves. Three cases are considered for estimating precipitation flux into the atmospheric loss cone. An analytical yield spectrum (AYS) approach is used to calculate energy deposition of electrons in the atmosphere of Ganymede. It is found that the intensities are inadequate to account for the observational intensities.
