Session ID#: 17838

Session Description:
NASA's Magnetospheric Multiscale (MMS) mission completed its first dayside season on March 8, 2016.  With a spacecraft separation as small as 10 km, MMS now probes the sub ion-scale structure of Earth's dayside magnetopause, observing the plasma and fields at comparable temporal resolutions for the first time.  Comparison of these observations with simulations has provided many new insights into the structure of the magnetopause boundary layer, including:  the structure of the electron and ion diffusion regions in asymmetric reconnection, the ion-scale structure of reconnection exhausts, the role of secondary islands in the reconnection process, the nature of turbulent fluctuations in the magnetosheath and low latitude boundary layers, the kinetic structure of Flux Transfer Events (FTEs), and the large scale topology of the dayside magnetopause.  We solicit abstracts investigating these and related topics using observations, theory and modeling, and laboratory experiments, with emphasis on relevance to the interpretation of MMS data.
