Nielsen, E., Bruns, M., Pardowitz, I., Perplies, H., Bemmann, L., Janhunen, P. and Huuskonen, A. (1999). STARE: Observations of a field-aligned line current. Geophysical Research Letters 26: doi: 10.1029/1998GL900252. issn: 0094-8276.

For the first time a magnetospheric line current entering the ionosphere has been unambiguously observed. The observation was made with STARE (=Scandinavian Twin Auroral Radar Experiment), a ground based coherent radar system, which has been updated with modern computer technique, and recently taken into operation. A counter clockwise turning swirl of ionospheric electron drift velocities is synonymous with the presence of a line current flowing along the geomagnetic field lines into the ionosphere. A Flux Transfer Event on the magnetopause has been predicted to connect to the ionosphere via a line current. ¿ 1999 American Geophysical Union
