Abstract

The solar radius at 35 GHz has been determined from solar radio maps made with a pencil beam antenna of half-power beam width 2.8 arcmin at the La Posta Astrogeophysical Observatory during 1973 and 1974. The 35 GHz radius was found to be 2.57% ±0.88% larger than the photospheric radius. The sensitivity of the result to the method of determination is discussed.
