Abstract: Magnetic reconnection is a fundamental plasma process of key importance to several fields, especially to space sciences. Reconnection at Earth’s magnetopause drives magnetospheric convection and provides mass and energy input into the magnetosphere/ionosphere system thereby driving the coupling between solar wind and terrestrial magnetosphere. Despite its importance, the factors governing the location of dayside magnetopause reconnection are not well understood. Though a few models can predict X-line locations reasonably well, the underlying physics is still unresolved. In this study we present results from an intensive analysis of several hundred reconnection regions observed by MMS to determine what quantities are most strongly associated with the occurrence of dayside magnetopause reconnection. We also attempt to answer under what upstream conditions each global X-line models are least reliable.
