Knudsen, D.J., Kelley, M.C., Earle, G.D., Vickrey, J.F. and Boehm, M. (1990). Distinguishing Alfvén waves from quasi-static field structures associated with the discrete aurora: Sounding rocket and HILAT satellite measurements. Geophysical Research Letters 17: doi: 10.1029/90GL00672. issn: 0094-8276.

We present and analyze sounding rocket and HILAT satellite measurements of the low frequency (&Sgr;p-1, which we argue to be due to the presence of Alfv¿n waves incident from the magnetosphere and reflecting from the lower ionosphere, forming a standing wave pattern. These waves may represent an electromagnetic coupling mechanism between the auroral acceleration region and the ionosphere. ¿ American Geophysical Union 1990
