✦ Synopsis

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 ,~ 5303, Fex ~ 6374, 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 Te= 1.6 x 106-1.2 x 106 and log Ne=8.5-9.5, and that a decrease in T, and an increase in N~ occur with decreasing height.

In 1957, the author has described the morphology of the monochromatic corona, using synoptic charts of the green line intensity. He drew attention to regions of very low emission that could be identified on several consecutive rotations. For these features, he coined the term 'L6cher' what means 'ho

The flash spectra of the partial Sun and the chromosphere were obtained at the total solar eclipse on 7 March, 1970. We studied the distributions of the surface brightness of the continuum at six wavelengths in the visual region to compare them with the previous observations and the existing model a

Polarigraphic observations of the 7 March, 1970 eclipse were made at Miahuatlfin (Mexico) with a camera of 120 cm focal length. A polarizing filter in front of the objective could be adjusted at 8 different positions, 22.5 ~ apart. Reduction of eight photographs of the white light corona yields pola
