Fig. 9

Radial diffusion of ultra-reltivistic electrons (6.3 MeV) shown in the top panel. Also shown in the top panel is the comparatively slower radial diffusion during October 2012. Compare to much slower diffusion seen in previous strong storm in October 2012, black dashed lines show the slope of inward drift. The rest of the panels show Dst, Kp, AL, and solar wind parameters.
