Riometer records of cosmic noise absorption obtained at Macquarie Island in the South Pacific and from several stations in the magnetically conjugate area in Alaska demonstrate a high correlation of auroral zone absorption events in the northern and southern hemispheres. Not only the periods of absorption, but also the magnitudes and structure of the events, are found to be closely, but not exactly, related in the two hemispheres. Both statistical studies and specific absorption events are discussed. The results are sufficient to demonstrate that there is a magnetically conjugate area of narrower dimension in latitude than in longitude. The results are not adequate to indicate whether the occasional breakdown of conjugacy is observed because: the riometers are not located at the actual conjugate points; the disturbance phenomena are sometimes nonsymmetrical between the two hemispheres; or the conjugate points are nonstationary.
