A series of spectrograms of the inner solar corona were obtained at the total solar eclipse of 30 May 1965 using a fast spectrograph with a circular slit that recorded the spectrum from 23000 to 29000 at all position angles around the limb simultaneously. In this paper absolute intensity is given as

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
