The high accuracy reached by solar limb observations, by helioseismic measurements and by Standard Solar Model (SSM) calculations suggests that general relativistic corrections must be included when discussing the solar radius. The Allen value (R ⊙ =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.
