abstract. We present a sequence of flux transfer events observed by SuperDARN in the northern hemisphere and their counterpart signatures in southern hemisphere auroral images taken by the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) spacecraft on 31 August 2005. The observations indicate that auroral features associated with each FTE are entrained within a relatively narrow convection throat, with east-west convection flow in the northern hemisphere and west-east auroral motion in the southern hemisphere, consistent with the By > 0 nT orientation of the IMF. We compare and contrast these observations with previous FTE studies and discuss the conclusions that can be drawn for reconnection geometries at the magnetopause.
