International audienceWe report the discovery of a new M9.0 dwarf at only 8.2 pc, which we identified in our search for nearby ultracool dwarf (I-J>= 3.0, later than M8.0) in the DENIS data base. We measure a very high proper motion of 2.5arcsecyr-1. The PC3 index measured from its low-resolution spectrum gives a spectrophotometric distance of 8.2 pc. This makes it the third closest M9.0 dwarf
