Abstract
The high accuracy reached by solar limb observations, by helioseismic measu rements and by Standard Solar Model (SSM) calculations suggests that genera l relativistic corrections must be included when discussing the solar radiu s. The Alien value (R-circle dot=695.99 +/- 0.07 Mm) has to be reduced by 1 .5 km, This correction, which is small compared with the present accuracy, should be kept in mind for more precise measurements and/or calculations in the future.
