A cannonball star candidate in Canis Minor

We report on the identification of a cannonball star candidate toward the direction of Canis Minor. The star is called PSS 544-7 and it has been selected as a result of a search in SIMBAD at CDS. With uncorrected colors B − V = 1.58 ± 0.15, V − J = 2.66 ± 0.14, V − KS = 3.38 ± 0.23, J − H = 0.675 ± 0.167, H − KS = 0.046 ± 0.244, J − KS = 0.721 ± 0.219, the object exhibits a significant proper motion, 401 ± 13 mas/yr. Based on the object's photometry, we conclude that it is likely a M-dwarf with an unusually high velocity perpendicular to the galactic disk. Its photometric parallax yields a distance estimate of 210 ± 60 pc, a tangential velocity of 399 ± 127 km/s and a W-component >350 km/s. If our interpretation is correct, given its location and kinematic signature, the object is a candidate cannonball star ejected by a star cluster.
