A close double star, on Orion's right shoulder. A 5, bright white; B 7, pale white. This elegant object was discovered by ♅., and his observations compared with late results seemed to show a retrograde motion in the angle of position; but this has not been confirmed by the latest measures. It was considered too difficult for the five-foot equatoreal by H. and S., in 1822; and their measures were therefore cautiously advanced. Nor did H. place reliance on his angle, 214°33', taken afterwards with the seven-foot telescope. I therefore re-attacked it under every favouring circumstance in 1839, and place pretty good confidence in the results obtained. The other observations are:♅. Pos. 217°50' Dist. 1".0± Ep. 1780.06A line from the leading star of Orion's belt carried towards β Tauri, passes 32 Orionis at rather more than 6°, where it will be seen just to the eastward of Bellatrix.
