Macrospicule at the solar limb near the south pole is observed in the light of the O v line at 62.9 nm, corresponding to 230 000 K; pseudo colours represent radiance (left) and Doppler motion (right). The Doppler flows are scaled from +30 km s-1 (red) to –30 km s-1 (blue). One half of the plasma ejection moves towards us, the other half away from us; the spicule swirls like a tornado along a magnetic field line with an Earth-sized diameter rotating at  ± 30 km s-1.
