A small number of very faint very red stars have been discovered in CCD frames taken near the center of the Pleiades cluster. The V, I, and K photometry for these stars is consistent with the expected luminosity and temperatures for brown dwarfs of mass about 0.07 solar mass at the distance and age of the Pleiades. It is concluded that these are the first identified single brown dwarfs of known age, distance, and metallicity. 16 refs.
