The solar radius derived from limb-darkening scans obtained in 1981 and from 1986 to 1990

Solar-radius data are presented which result from observations made in 1981 and from 1986 to 1990. These data, which are a by-product of the limb-darkening observations made by Neckel and Labs (1984, 1994), do not show significant deviations from the value which is adopted from Auwers (1891) for computations of solar eclipses and of the Sun's ephemeris in theAstronomical Almanac.
