The locations of flarcs and chromospheric absorption features on May 21 and 23, 1967, are compared with a series of ]-Ia magnetograms. Each of the four major flares included in the study developcd as double emission ribbons lying at positions of steep field gradient on opposite sides of the boundary

We have measured the longitudinal component, Bll, of the magnetic field in quiescent prominences and obtained a relationship between BII and 0, where 0 is the angle between the long axis of the prominence and the north-s0uth direction on the sun. From this relationship we deduce a distribution funct
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
We determine magnetic fields and electric currents in three prominences without simplifications used in our previous papers.
