Scientific paper

We present a measurement of the trigonometric parallax for a nearby very low mass star recently discovered by Delfosse et al. (\cite{Delfosse01}). Using schmidt plates measured on the SuperCOSMOS plate scanning machine we find a parallax of pi = 192+/-37 mas, giving a distance of d=5.2+1.2-0.8 pc. Using this distance we find the absolute magnitude and kinematics for the object to be consistent with an intermediate-age disk object of mass 0.08 Msun. This star is clearly nearby and is on these measurements between the 30th and 86th closest known stellar system to the Sun; it could be the closest M 9 dwarf to the Sun.
