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 Teff = K. We determine for which evolutionary models by Baraffe et al. (2003, A&A, 402, 711) suggest an age of around 0.1–0.35 Gyr consistent with its high activity. The age and luminosity of GJ406 correspond to a wide range of plausible masses (0.07–0.1 ).
