High‐latitude ULF waves at all frequencies are reviewed with emphasis on simultaneous measurements in both hemispheres. The seasonal variation of interhemisphere high‐latitude data is valuable in helping to understand the topology of the magnetosphere. The frequent occurance of Pc 1–2 pulsations at high latitudes and in the polar cap is discussed. Evidence for ground detection of flux transfer events via magnetic pulsations is reviewed. The correlation of high‐latitude pulsation data with other ground techniques of measuring particle precipitation is presented to better define the subset of high‐latitude ULF that is produced by local current systems fed by particle precipitation and field‐aligned currents. Finally, simultaneous ground and spacecraft measurements of ULF are reviewed which provide information on the propagation of ULF across such boundaries as the magnetopause and the ionosphere.
