Green line observations of the March 1970 coronal enhancements

Monochromatic observations of a double coronal enhancement were obtained on 3 March and 17 March 1970. These data are used, along with the assumption of cylindrical symmetry, to calculate the emittance of the Fexiv 5303 Å lines as a function of height. These estimates are then used to find the electron density and the density of ions in the ² P _3/2 level of the ground state as a function of height above the limb.
