At this conference Mayor et al. announced evidence for an exoplanet in orbit around HD10647. Here we consider the Anglo-Australian Planet Search dataset for HD10647. Our dataset amply covers the claimed orbital period and is of substantially higher precision. We do ¯nd weak evidence for an exoplanet with similar parameters to those announced by Mayor et al. However, since the amplitude of proposed planet is rather similar to the jitter velocity we are not in a position to con¯rm a planetary interpretation. We note that claims of small amplitude planets (<20 ms¡1) around active stars are fraught with uncertainty, e.g. ² Eri.
