MMS Observations of a Flux Transfer Event Immersed in a Super-Alfvenic Flow

Abstract: We discuss plasma, magnetic and electric field data for a flux transfer event (FTE) to highlight improvements in our understanding of these transient reconnection signatures resulting from high resolution data. The ~20 s-long, reverse FTE, which occurred south of the geomagnetic equator near dusk, was immersed in super-Alfvenic flow.  We focus on (i) providing the first observations of field line draping of the external field around the flux rope; (ii) motivating the use of non-force free methods in modeling FTE flux ropes.
