Tethered two-point measurements of solitary auroral density cavities

Autor: H. G. James, D. D. Wallis, David J. Knudsen

Publikováno v: Geophysical Research Letters. 26:2933-2936

The OEDIPUS-C sounding rocket observed localized plasma density depletions in the topside auroral ionosphere using two Langmuir probes situated on separate subpayloads several hundred meters apart. One probe was biased in electron saturation (+5 V) a

Studies of auroral arcs using Freja satellite and ground-based data

Autor: J. H. Clemmons, Gerhard Haerendel, Harald U. Frey, D. D. Wallis, J Vogt, H. Lühr, E. Rieger, M. H. Boehm, Otto H. Bauer

Publikováno v: Advances in Space Research. 18:107-110

During two Freja passes over auroral arc systems special wide-angle CCD cameras were operated from the ground. Comparisons of the optical observations with satellite-measured plasma parameters are performed. Motions of fine structures of the arcs are
