Top: height-time profile of the flux rope and CME frontal loop (diamond symbol) from AIA 94 Å and LASCO C2/C3. Middle: speed of the flux rope and the CME frontal loop, plotted with GOES soft X-ray profile (red curve). The triangle symbol (between two vertical dotted lines) shows the speed of the type II radio burst excitor. Bottom: dynamic radio spectrum (25−180 MHz) from Learmonth radio observatory. F and H represent the fundamental and second harmonic emissions of the type II radio burst.
