Abstract
The appearance of quiescent solar prominences most often resembles a wide curtain or a fencemade of a vertical palisade. It is hard to imagine that such a structure can be connected or even formed by amagnetic flux rope, that is, a bundle of force lines twisted into a cylindrical helix, which sometimes clearlymanifests itself in active region filaments. However, with a relatively small activation of the prominences,when the plasma composing them begins to move along the field lines, the structure of the magnetic flux ropecan be discerned. An example of a quiescent prominence is shown, in which rotational motion is observedalong helical trajectories outlining the flux rope. The rotation is clearly visible in the time-distance diagram,which is composed of narrow strips of images of the prominence along the trajectory of motion
