Three methods of approximation are described and are used to separate the primary twilight brightness from the observed brightness. Photoelectric observations obtained at the Majaky Observatory in 1968-69 (Zaginayilo) are combined with observations from a balloon and from Pic-du-Midi Observatory (Link et al., 1967) to derive the atmospheric scattering phase functions at 0.37 μ and 0.58 μ as a function of height.

Comparison of these data with data for a Rayleigh atmosphere provide information on the optical properties of dust in the upper atmosphere.
