Scientific paper
A method has been devised which, under appropriate observational circumstances, enables a direct determination to be made of the optical thickness t(L) of high-rising H-alpha solar loops observed on the disk. It is applicable to both bright and dark loops and requires no knowledge of the source function in the loop; it is best adapted to optically thin ones. The technique has been successfully applied to four loops observed under various circumstances, giving values of t(L) ranging from 0.06 to 1.3. It is not restricted to H-alpha loops but, in principle, could also be applied to chromospheric and coronal fine structures observed in the visible, EUV, and X-ray regions.
