  We have used the Palomar 200" Adaptive Optics (AO) system to directly detect
the astrometric brown dwarf GJ 802B reported by Pravdo et al. 2005. This
observation is achieved with a novel combination of aperture masking
interferometry and AO. The dynamical masses are 0.175$\pm$0.021 M$_\odot$ and
0.064$\pm$0.032 M$_\odot$ for the primary and secondary respectively. The
inferred absolute H band magnitude of GJ 802B is M$_H$=12.8 resulting in a
model-dependent T$_\mathrm{eff}$ of 1850 $\pm$ 50K and mass range of
0.057--0.074 M$_\odot$.
