Following comments of readers of our paper on latitudinal libration driven flows in triaxial ellipsoids (Vantieghem, Cébron & Noir Reference Vantieghem, Cébron and Noir2015), we would like to append a correction that does not impact in any way the results of our study. In figure 2(a) of the original manuscript, the bulge of the Moon points towards the centre of the Earth when the rotation and orbital rate are equal. However, it was pointed out that the bulge is pointing in this direction at the apogee and perigee and not at the equinox. The correct orientation of the satellite during various stages of its orbit is shown in figure 1 below (which replaces figure 2(a) of the original manuscript).

Figure 1. Mechanism giving rise to librations in longitude. Shown are the host body, its satellite at different positions along its orbital trajectory and the gravitational torques resulting from variations in the orbital speed $\unicode[STIX]{x1D6FA}_{orb}$ .

Acknowledgement

We are grateful to N. Rambaux for pointing out an error in the initially published version of figure 2(a).
