An early view of footpoint asymmetry as deduced from the polarization properties of microwave impulsive bursts. The curly lines show Larmor motion of electrons in the stronger and weaker-field legs of a coronal loop; the authors must have left the open field lines at the top of the diagram in the hopes that some electrons would somehow "escape" there and thus produce one of the very common type III bursts.
