We re-discuss the reality of the four periods near 0.5 d and reject the claim (Balona et al., these proceedings) that μ Cen exhibits a single ∼0.66-d period caused by co-rotating clouds. The alleged 0.66-d period is not genuine but results from the simultaneous proximity of this value to the beat period between the true 0.28- and 0.5-d periods as well as to a 2-c/d alias of the 0.28-d period.
