Magnetic reconnection at the dayside magnetopause with Double Star Tc1 data.

In a previous study we examined all the dayside magnetopause crossings that occurred during the first year of the Double star Tc1 mission, and identified 23 passage of Tc1 near the X-line. This observations indicated the presence of a reconnection line hinged near the subsolar point and tilted according to the observed magnetosheath clock angle, consistently with the component merging model. Here we show the results of a new analysis that confirms the agreement of the observations with the model.
