The TYCHO-2 proper motions of this object are very different from other catalogues, for example, the recent UCAC4 (-15.9 (8.3), 10.7 (2.3)). Even the UCAC4 errors being greater than TYCHO-2, its proper motions seem closer to the actual ones. In fact, I suggest that in this case TYCHO-2 is using as first epoch an AC position that belongs to a nearby star about 18" at north-east (TYC8154-1544-1, without proper motions in the catalogue). Using UCAC4 proper motions the star can be a member of the Carina young association (see Torres et al., 2008, Handbook of Star Forming Regions, Volume II: The Southern Sky ASP Monograph Publications 5, 757). Its high Li content is compatible with the age of Carina association.
