New radial velocity (RV) measurements were obtained for the star β Crt, which has been suspected to be a Sirius-like binary. Although a preliminary period analysis indicated a period as short as 8 days, no significant change of the RV over 8 nights could be detected. While this result is similar to what Smalley et al. (1997MNRAS.284..457S) found, our value of the mean RV is much smaller. We, therefore, conclude that the RV of β Crt is indeed variable, maybe but not necessarily due to binarity, but so far no period can be determined.
