Flux Transfer Events (FTE) are commonly observed at the magnetopause and are generally interpreted as the product of magnetic reconnection occurring there.  In this study, we analyze observations of several FTEs, such as the event of August 15, 2015, 13:25 UT. This case consists of an isolated FTE detected during quiet conditions and the burst data are available for the 4 spacecraft, which were in good tetrahedron configuration. We report detailed analysis of the fine current and plasma structure of the FTE and of the complex set of secondary current structures surrounding it. The organization of the current distribution and of the plasma features will be discussed considering the magnetic reconnection paradigm. We then compare this reference event with other FTEs analyzed with the help of burst data.
