Summary:Magnetic field observations obtained by the Pioneer Venus orbiter during 130 orbits in the Venus wake were examined for possible surface-correlated features or any intrinsic magnetic moment. No surface-correlated magnetic fields were observed, but the threshold for the detectability of such fields at Venus is about an order of magnitude greater than that of the Moon. Using measurements averaged in 72 10° X 10° bins a planetary magnetic dipole moment of 0.87 + or - 3.00X1021 Gauss-cm3 was obtained. Thus the upper limit of the present-day Venus moment is <4 X 10-5 of the terrestrial moment. [P.Br.]
