The aim of this work is to compute the amplitude of the limb darkening fluctuations due to oscillations in order to compare with the observations made with the heliometer at the Pic du Midi (Rösch and Yerle 1983–1984). It is shown that 5 min oscillations lead to variation in the brightness gradient of less than 2%.
