We propose to use the unique capabilities offered by ISO to obtain broad band imaging & low resolution mid-infrared spectrum of the newly discovered brown dwarf DENIS-P J0205-1159 (1). A large fraction of the energy is emitted in that wavelength range. Old brown dwarfs, like our new isolated objects, have cooled to sufficiently low temperatures that dust forms in their atmospheres (Allard 1997, Tenerife BD conference). Their atmospheric structure is still poorly understood. It is thus essential that the atmospheric models can be constrained by observed energy distributions, and especially important is the SED in the mid-IR where continuum blanketing by dust will occur. Spectroscopy of one Brown Dwarf would test the models and lead to a better understanding of Brown Dwarf atmospheres.
