We present a measurement of the trigonometric parallax for a nearby very low mass star recently discovered by Delfosse et al. (2001). Using schmidt plates measured on the SuperCOSMOS plate scanning machine we find a parallax of $\pi = 192\pm37$ 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 $0.08 {M}_{\odot}$. 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.

Key words: astrometry -- stars: low mass -- stars: individual: DENIS 1048-39
