Summary

Limb observations of quiescent solar prominences have revealed them to be composed of many fine structures. Also observations in Hα and UV lines suggest that quiescent prominences are made up of many clusters of small-scale loops at different temperatures inclined to the filament axis, with the CIV structures more extended than the Hα ones.

Active-region prominences have been modelled previously as single cool loops along the prominence. However, other observations suggest that they could be interpreted in terms of many loops of plasma inclined to the filament. Our aim has been to take into account such observations and to construct a model for the fibril structure of solar prominences in terms of slender flux tubes, in which the main observed parameters of both quiescent and active-region prominences are reproduced.
