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.
