Abstract
Galactic and non-galactic components of the diffuse H-alpha and H-beta night sky emissions were resolved with a Fabry-Perot spectrometer. The non-galactic component of both lines accounts for most of the emission at galactic latitudes greater than 30 deg. The intensities of the galactic component yield values for the average ionization rate per hydrogen atom that are between 10 to the minus 15th power and 10 to the minus 14th power s sup minus 1 assuming steady state ionization.
