✦ Synopsis

Applying a new data visualization technique to magnetic ÿeld observations from the Greenland west coast array we observe that Pc5 wave power spatial=temporal variations in the morning=pre-noon sector are closely related to the location and intensity of the auroral electrojet. This e ect is not taken into account by existing theories of ULF Pc5 waves, but it could be signiÿcant for the development of more adequate models. Consideration of the most evident interpretation schemes shows that there is no simple explanation of this e ect. An adequate interpretation may require a substantial revision or augmentation of existing Pc5 models.
