[en] Analysis of a time-lapse sequence of Hα spectrograms of chromospheric spicules has yielded radial, tangential, and total velocities for 15 spicules at the 4000-km level. In projection on the photosphere, spicules move along cyclic trajectories, ideally almost ellipses, so that a spicule vibrates as a whole as though it were elliptically ''polarized.''
