From: The first super geomagnetic storm of solar cycle 24: “The St. Patrick’s day event (17 March 2015)”
Geomagnetic activity index (Dst: top panel) and Wind observed in situ solar wind parameters (second–eighth panels) during 16–18 March 2015. From top to bottom Dst, latitude (θ B ), and longitude (ϕ B ) of the magnetic field in GSE coordinates. B z of the field in GSE, proton temperature (T), bulk speed (V), number density (Np), and magnetic field magnitude (B). The blue horizontal line in the third panel from the bottom represents the scheme’s identification of the extent of this MC candidate (Lepping et al. 1990). The purple-solid line and blue-dashed vertical lines represent the IP shock and the front boundary of the MC, respectively
