Associated plot of ICME parameters obtained from Omni data for the type II burst and CME that occurred on 6 July 2006. The top panel illustrates the Bx, By, and Bz vector components of the B field (G); the middle panel shows the average strength of the B field vector (G); and the bottom panel shows the flow speed across the timeline of the event. The vertical dotted line shows the near-Earth shock arrival at 21:36 UT on 9 July 2006 and the grey-shaded region shows the start and end time of the disturbance in the plasma (Richardson & Cane 2010), starting at 19:00 UT on 9 July 2006 and ending at 21:00 UT on 11 July 2006.
