The solar eclipse of 12 November 1966 was used to study the coronal emission near the limbs in selected emission lines between 16 and 40 A. Eight fixed-wavelength, curved crystal spectrometers were carried in each of 3 rocket launches to an altitude of 290 km and monitored the flux in each of eight

โฆ Synopsis
A line to continuum ratio of the green line equal to 2.1 A was measured above the West limb at the height p = 1.75 solar radii during the eclipse. The lower limit to the abundance of iron relative to hydrogen obtained from these measurements is 4 โข 10 -5.
