We report on our serendipitous discovery that the objects Q 01323-4037 and Q 0132-4037, listed in the Veron-Cetty & Veron catalogue (2006) as two different quasars, are actually a quasar and a star. We briefly discuss the origin of the misidentification, and provide a refined measurement of the quasar redshift.
