Solar wind data from Wind and the Dst variation for three days, 8–10 October 2012. From top to bottom are plotted the IMF intensity (B), X-, Y-, Z-components in GSE coordinates (Bx, By, Bz), the degree of field fluctuations defined by the standard deviation divided by averaged intensity obtained from higher time resolution data (Sb/B), solar wind speed (Vsw), proton number density (N), number density ratio of He++ to H+ (He/H), proton temperature, plasma β, and the Dst index. The vertical dashed line indicates the shock arrival time (on 8 October at 04:12 UT) and the two vertical lines indicate the flux rope (from 8 October at 17:20 UT to 9 October at 18:30 UT). The red curves show the model values obtained from the fitting with a toroidal flux rope model. Adapted from Marubashi et al. (2017)
