| STF 668 | bet Ori = 19 Ori = Rigel. The companion is a spectroscopic binary and | |
| suspected visual double, although it remains unconfirmed. Magnitudes | ||
| of B and C very uncertain. Changed from IDS values (10.4 for B, C, and | ||
| BC). AD pair first mentioned by Mitchel in 1846 (Sidereal Messenger, | ||
| May 1847) but no astrometry included. See extensive notes by Burnham. | Bu_1906 | |
