High resolution white light colour pictures obtained during the 1981 total solar eclipse were used for a photometric analysis of the S-pole region. A small helmet-like streamer was visible over the S-polar limb overlying a faint polar prominence from the polar crown belt of filament channels that reached 87° latitude at the eclipse date. Typical electron densities deduced are ne ≅ 2×109cm-3 for the activated top of the prominence and ne ≅ 6×108cm-3 for the associated coronal structures. Upward velocities up to 160 km s-1 are obtained for the eruptive prominence parts. The authors found that dynamic processes are controlled by magnetic forces for fields B ≥ 3.5 Gauss, and that the coronal structures are apparently connected with the faintest and most dynamic parts of the prominence.
