We present a measurement of the trigonometric parallax for a nearby
very low mass star recently discovered by Delfosse et al. ([CITE]).
Using schmidt plates measured on the SuperCOSMOS plate scanning machine we find
a parallax of 
mas, giving a distance of
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 
. 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, brown dwarfs / stars: individual: DENIS 1048-39
