Three sources have been discovered in the embedded population of the Rho Ophiuchi cloud that have dereddened M(K) equal to or greater than 7. Comparison with theoretical models for evolution of low-mass stars shows that these sources are subtantially less luminous than expected for objects evolving onto the main sequence and of the age of the embedded cluster. The sources are probably substellar in mass, i.e., they may be young brown dwarfs. 19 refs.
