Abstract:
We statistically analyze Flux Transfer Events (FTEs) orientation and motion for different interplanetary magnetic field conditions to determine the location and orientation of reconnection lines on the dayside magnetopause. Our analysis is based on more than 70 estimations of FTE boundary normals and on determinations of the FTE orientations themselves. We perform Minimum Variance Analysis of the THEMIS magnetic field data within and in the vicinity of the FTE boundaries. We discuss the role of different reconnection processes on the orientation of FTEs. We analyze dependencies between orientation and direction of FTE motion. We compare obtained results with those expected by MHD global geospace general circulation model. We pay special attention to cases in which different methods give conflicting results and cases in which the orientations differ from those predicted by the models.
