HR 6046 has long been known as a single-lined binary with a late-K-giant primary star. The long period of just over six years and the large mass function led to several, so far unsuccessful, attempts to resolve the system interferometrically. However, we have detected the secondary spectroscopically, and present here the spectroscopic orbital elements. The secondary is nearly as massive as the primary, despite being much fainter. Comparison with late-type standard spectra suggests that it is also an evolved star.
