PFSS reconstructions of the coronal magnetic fields at three times showing the evolution of the global magnetic field from the SDO view (top panels) and from the STA view (lower panels). The three times, 23 January at 12 UT, 24 January at 18 UT, and 25 January at 0 UT, show the global magnetic field during the three stages described in the previous text. The green and magnetic lines show the open field lines of two polarities.
