Abstract (from CDS):

We report the discovery of a nearby star with a very large proper motion of 5".05±0".03 yr–1. The star is called SO 025300.5+165258 and referred to herein as a high proper motion star (HPMS). The discovery came as a result of a search of the SkyMorph database, a sensitive and persistent survey that is well suited for finding stars with high proper motions. There are currently only seven known stars with proper motions greater than 5" yr–1. The spectrum and measured tangential velocity indicate that the HPMS is a main-sequence star with spectral type M6.5. Trigonometric and photometric parallaxes have been determined, yielding distance estimates of 2.4+0.7–0.4pc (lower limit) and 3.6±0.4 pc, respectively. If the former is correct, the HPMS ranks third in the list of nearest stellar systems. If the latter is correct, it is 17th. A more precise trigonometric parallax measurement is expected to be completed near the end of the year.
