Abstract As a result of a collaborative rocket experiment carried out during the solar eclipse on 7 March, 1970, measurements have been made of the brightness of Lyman α from the corona, at heights between 5 × 104 and 5 × 105 km above the limb. The emission is shown to occur primarily through the resonance scattering of chromospheric Lyman α from the residual neutral hydrogen in the corona. Both the absolute value and radial fall-off of the brightness agree well with calculations based on solar density models. The Lyman α emission has similar variations around the limb to the white light corona, showing in particular an equatorial enhancement.
