Abstract

We report on our serendipitous discovery that the objects Q 01323-4037 and Q 0132-4037, listed in the Véron-Cetty & Véron catalog (2006, A&A, 455, 773) 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. © 2011 ESO.
