It belongs to the AB Doradus moving group
, meaning that it largely shares their motion, which has components ( U,V,W ) = ( -8, -27, -14 ) km/s in the LSR or "Local Standard of Rest" frame of reference. That is the area "local" to our sun on the galactic scale.
The sun has ( U,V,W ) = ( 10, 5, 7 ) km/s, so the relative motion is ( U, V, W ) = ( -18, -32, -21 ) km/s . Now, all we have to know is which direction it is from us in the LSR frame.
Let's see if we can "seat of the pants" it. The group is in the constellation Dorado and is about 90 degrees away from the galactic center in Sagitarius, so the first component, in the U direction, which represents motion toward the galactic center ...

Anyone see the movie "Melancholia"?
