TWA 12 was rejected as a TW Hydra Association member by Mamajek (2005; http://adsabs.harvard.edu/abs/2005ApJ...634.1385M ) based on a proper motion with large uncertainties. However, the modern UCAC3 proper motion has much smaller uncertainties than the value used by Mamajek (2005) (3UCAC 103-118398; pmRA, pmDec = -68.3+-2.7, -12.1+-1.5 mas/yr; Zacharias et al. 2010) and this new proper motion is very consistent with TWA membership.
