Abstract

Identifications are proposed for twenty of the twenty-eight coronal lines observed in the spectra obtained during a rocket flight into the path of the 7 March, 1970 solar eclipse. The methods by which the lines have been identified are discussed. Most of the lines identified are from forbidden transitions between levels in the ground 2pn and 3pn configurations in high ions of magnesium, silicon, sulphur, iron, and nickel. The temperature range represented is from 6.9 × 105 K to 2.5 × 106 K. The classification of three lines of Fexii and two of Nixiv has led to a revised identification for the near ultraviolet 2D3/2-2P1/2 transition in Fe xii. This transition can be identified with the line at 3072 A rather than that at 3021 A as previously suggested in the literature.
