Abstract
Spectrographic observations of the flash spectrum were made by the Kwasan Observatory at the total solar eclipse on 7 March, 1970. The integrated intensities of Fexiv λ5303, Fex λ6374, and the continuum were measured on the spectrograms as a function of height above the Sun's limb. It was found that a large amount of emission in the coronal lines originates in the interspicular regions of the chromosphere. Analysis of the data yielded that the interspicular regions consist of coronal material of T e = 1.6 × 106–1.2 × 106 and log N e = 8.5–9.5, and that a decrease in T e and an increase in N e occur with decreasing height.
