Scientific paper

Viking television photography of two dust storms that occurred during the Viking extended mission are used to show that the enhancement of the opposition effect at short wavelengths reported during the 1967 and 1969 oppositions does not appear to be an atmospheric effect, as previously suggested. The brightness changes near 0 deg phase as seen by the Viking Orbiters during the June 15, 1977, dust storm are modeled, yielding first-order aerosol parameters that tend to suppress the opposition effect in violet light. It is proposed that the opposition-effect phenomenon, if real, might be characterized by assuming a surface covered with a particle microstructure of the same single-scattering albedo found for the June dust-storm aerosols, combined with a lunar phase function (macrostructure).
