We find that at around 25 solar radii (R ⊙), the shape of a shock wave is very spherical, with a ratio between the lateral and radial dimensions (minor radii) remaining at around b/a ≈ 1.03 and a radial to lateral speed ratio (V R /V L)≈1.44. The CME starts to slow down a few tens of minutes after the ...
