a Plasma pressure and b, c parallel current density in the Y-Z plane at X = − 7 Re. In c, parallel current is also drawn on the surface at 3 Re. The yellow and white lines indicate the current line and the magnetic field line, respectively, extending from Arcs 1, 2 (high-latitude aurora), and 3 (quiet arc) at T = 43.7 min. The color codes indicate the parallel current density (negative upward in the Northern Hemisphere). (Adapted from Ebihara and Tanaka 2016)
