Scientific paper

Radial velocity measurements on the solar Mg I 5183.6 Å Fraunhofer absorption line in the zodiacal light spectrum have been made with a microprocessor-controlled servo-stabilised Fabry-Perot interferometer. Observations were made at 5° and 10° intervals in the ecliptic plane between morning and evening elongation of 25° from the Sun, and these new data are of greater precision and coverage than any previous observations. Obtained over a two year period, the observations show a consistent evening/morning asymmetry in the radial velocity curve with the Gegenschein receeding from the Earth at a velocity of ≡2.5 km s-1. These data do not support the hypothesis that the majority of interplanetary dust grains are in hyperbolic trajectories.
