[88.01] On the Constancy of the Solar Diameter

The solar radius and its variation have now been measured during most of a solar cycle from the Solar and Heliospheric Observatory, using the Michelson Doppler Imager. These instruments provide unique astrometric data from above the Earth's atmosphere. A new analysis based on MDI data yields a refined measurement of the solar radius and no evidence of secular or solar cycle size variations.
