Neutron diffraction is used to examine the polarization of weak static antiferromagnetism in high quality single crystalline URu2Si2. As previously documented, elastic Bragg-like diffraction develops for temperature Τ HO = 17.5 K at q = (100) but not at wave vector transfer q = (001). The peak width indicates correlation lengths ξc = 230(12) A and ξc = 240(15) A. The integrated intensity of the Τ-dependent peaks corresponds to a sample averaged c-oriented staggered moment of υc = 0.0221(1)υB at τ = 1.7 K. The absence of τ-dependent diffraction at q = (001) places a limit υ υ on an f - or d-orbital based in-plane staggered magnetic dipole moment, which is associated with multipolar orders propsed for URud2^Si2.
