Fig. 10From: The February 24, 2010 substorm: a refined view involving a pseudobreakup/expansive phase/poleward boundary intensification sequenceComparison of THEMIS D (bottom), THEMIS A (middle), and Akulivik magnetic fields from 4:20 to 4:45 UT on February 24, 2010. The spacecraft data are in GSE coordinates, with spacecraft positions at 4:30 UT shown in the caption. The ground magnetic fields are in local magnetic coordinates. Color coding for components with the same designation in both systems are B X (black), B Y (red), and B Z (blue). Timing barsas in Fig. 9 Back to article page
