Multiple Reconnection Lines at the Dayside Magnetopause

Recent 2.5D global hybrid simulations investigated the formation of flux transfer events (FTEs) and their convection and interaction with the cusp. Multiple FTEs have been reported with a size range from a few hundred to thousands of km. Based on these simulations, we have analyzed several Polar cusp crossings in the northern hemisphere to search for the signature of such FTEs in the energy distribution of downward precipitating ions: overlapping, parallel to the ambient magnetic field, streaming ion beams.
