Overview of the observed reconnection region. Left: Schematic of event, showing the magnetic null, the Electron Diffusion Region (EDR) (blue) and surrounding region on the scale of the ion inertial length \(d_i\) (green). Numbered circles indicate the locations of MMS spacecraft 1–4 at one time snapshot. Right: the MMS orbit and the MMS spacecraft formation for the date of interest. Panel (a) plots the MMS orbit projection onto the GSE x–y plane. The red triangle shows the MMS location at the time of reconnection event. The green circle and blue diamond correspond to the start and the end of the orbit on 19-09-2015, at times 01:00 and 23:00, respectively. The dashed blue curve is the approximate location of the magnetopause at the time of reconnection. Panel (b) plots the MMS orbit projection on the GSE x–z plane, symbols are the same as these in panel (a). Panel (c) shows the spacecraft tetrahedron configuration at the time of reconnection, the MMS spacecraft 1–4 positions are shown in black, red, green and blue, respectively.
