A near-infrared excess emission superposed on the coronal continuum at ≡4 R_sun; from the Sun was first observed at 2.2 μm by Peterson and MacQueen during the total solar eclipse in 1966. The authors have carried out observations of near-infrared brightness distributions of the solar corona, using a balloon-borne photometer, during the total eclipse on 11 June 1983 in Indonesia. Emissions in excess of the strong coronal background emission were recorded in some of the scans at ≡4 R_sun; from the Sun. The spatial distribution of the excess emission implies the existence of a circumsolar ring of dust lying approximately in the ecliptic plane.
