Several dayside magnetosheath flux transfer events (FTEs) have been observed at high temporal resolution by the four-spacecraft MMS mission. In this study, we examine ion energy spectrograms, ion moments, and ion distribution functions for several long duration magnetosheath FTEs observed by MMS. For these cases, the spacecraft were positioned at similar locations (i.e., south of the equatorial plane, post-noon local time sector). The ion observations are placed in context with electron energy spectrograms parallel and anti-parallel to the observed magnetic field and the location of MMS relative to the predicted reconnection line location as determined from convected solar wind conditions. This combined set of observations provide important information on the formation, topologies, and evolution of FTEs.
