The authors report the development of a reverse sense convection cell in the polar ionosphere from auroral images coming from UV Viking probes. The cell was observed to grow on the dusk side of the north polar oval, near the transpolar arcs. As it grew it seemed to displace the arc system toward dawn. They compare their observations with a model in which magnetic merging in the magnetopause produces such convection cells, typically associated with horse-collar or teardrop auroral features.
