Measurements of the polarization of intense terrestrial kilometric radiation obtained with planetary radio astronomy experiments on Voyager‐1 and 2 during the early portions of each flight show the signals to be predominantly left‐hand circularly polarized. Since these emissions were most probably generated above the Northern hemisphere auroral zone, we conclude that the radiation is emitted primarily in the extraordinary mode.
