We present results of modelling the bulk of the spectral energy distribution (0.35-5 µm) for GJ406 (M6V). Synthetic spectra were calculated using the NextGen, Dusty and Cond model atmospheres and incorporate line lists for H₂O, TiO, CrH, FeH, CO, MgH molecules as well as the VALD line list of atomic lines. A comparison of synthetic and observed spectra gives T_eff=2800±100K. We determine M_bol=12.13±0.10 for which evolutionary models by Baraffe et al. (2003A&A...402..701B) suggest an age of around 0.1-0.35Gyr consistent with its high activity. The age and luminosity of GJ406 correspond to a wide range of plausible masses (0.07-0.1M_☉).
