AB: Magnetic reconnection is an important process for the transfer of solar wind plasma to the magnetosphere, and one which has been simulated in many three dimensional numerical models. This talk will present the results of a study of reconnection at the Earth's dayside magnetopause using the Lyon-Fedder-Mobarry (LFM) global magnetospheric simulation code, a code based on the equations of magnetohydrodynamics where the frozen-in condition is broken via numerical resistivity. In this study we were able to identify regions of magnetic reconnection at the magnetopause and categorize them as component or anti-parallel in nature for several IMF clock angles. We will also present results summarizing the time dependence of these regions and how magnetic reconnection depends on the spatial resolution of the simulation.
