The radial velocity measurements of the long-period spectroscopic binary Alpha 1 Cru are presented. These new observations cover the maximum of the radial velocity curve and yield an improvement on the orbital elements found by Thackeray and Hill (1974). The new gamma velocity strengthens the proposed membership of Alpha 1 Cru in the Sco-Cen association.
