                         traversed the magnetopause from the magnetosphere to the 
                         magnetosheath encountering evidence of magnetic reconnection and a 
                         tiny flux transfer event (FTE) on the magnetosheath side of the 
                         magnetopause boundary layer. The FTE exhibited a large 
                         negative-positive bipolar variation in the normal magnetic field 
                         component (BN ), an enhanced (negative) north-south component 
                         direction (BL), and a variation in the third component BM 
                         resembling a W shape with negative values close to the edges and 
                         positive values near the center. Using the tetrahedron formation, 
                         we estimate that the FTE moved southward and duskward with a speed 
                         of VFTE = 324 km/s. The FTE size in the transverse direction is 
                         518 km, which corresponds to 4.42 ion gyroradii. We identify an 
                         internal layer where the electron bulk flow velocity exhibits 
                         different behaviors at each of the four spacecraft and the current 
                         density was more intense at two spacecraft. Within the FTE's core 
                         region, the ion bulk flow behavior was similar for all four 
                         spacecraft. Using the velocity obtained from timing analysis, we 
                         estimate a dimension of this core region to be 181.4 km, which 
                         corresponds to 1.5 ion gyroradii. It is evident that the internal 
                         region is not large enough to affect the ion behavior but can do 
                         so for electrons. We conclude that the FTE's core is an 
                         electron-scale substructure.",
