Abstract
THIS communication concerns recent developments in the determination of the lunar gravity field from the accelerations experienced by the lunar Orbiters during their motion around the Moon. I shall refer to the papers by Muller and Sjogren1,2 which present, in the form of a map of equigravity contours, the final result of their reduction of the raw doppler data recorded during the actual motion. The adopted datum is the accelerations due to the second order gravity harmonic, so that in the contour map they give the surface gravity of the locus minus the local accelerations corresponding to the second harmonic.
