Abstract
We have discovered that the nearby double-lined spectroscopic binary B Y Draconis has a proper motion companion 17 arcsec to the northeast. P hotometric measurements indicate that the companion is an M5 dwarf lyi ng on the main sequence. Studies of this third component could prove v aluable in determining the evolutionary state of the system. (C) 1997 American Astronomical Society.
