We combine simultaneous WIND/GEOTAIL direction‐finding analyses of terrestrial 2f p radio emission to provide the first 3‐D source location by two spacecraft triangulation. These observations were made when WIND and GEOTAIL were relatively close to the electron foreshock and to each other. For two cases presented the 2f p radio source centroid was stationary and located in the upstream wing of the electron foreshock region some 15‐50R E from the contact point. In a third case the 2f p source centroid followed the change in orientation of the electron foreshock.
