Three quiescent prominences were observed in the Ca ~I K-line and a fourth one also in the H-line at Oslo Solar Observatory, Harestua, and reduced by Rustad (1974) and by Engvold et al. (1980). These data are used to study the distribution of the line-of-sight velocity component, N(uo). It is pointe

On the basis of Kippenhahn and Schltiter's magnetohydrostatic model of a quiescent prominence we have attempted to study the effect of a rotational velocity field in it. We find that a physically plausible solution is not possible in the vertical plane. A possibility, however, is shown in the horizo
We present measurements of the middle Balmer decrement (n = 10-22) in a number of quiescent prominences. The average decrement continues smoothly the trend of the decrement determined in our previous work on the earlier Balmer lines. The range of Tex is found to be 3450-11 000 K, consistent with the
