RAO 39	RoboAO finds 2 companions - Optical? 2MASS: B at 32.4" 145.3d, below	RAO2015
	the MS, optical? Tokovinin & Lepine (2012) miss AB but list an optical	Tok2012c
	companion at 1733".	Tok2014d
	AB: A is SB2 with P = 26.2 days (Griffin & Suchkov 2003). The tertiary	Grf2003
	companion B at 2".8 did not move substantially in a year since its
	discovery by Riddle et al. (2015), but the PM of the main component A	RAO2015
	is small and the astrometry is not conclusive. B is located below the
	MS on the CMD, although still within the errors of its photometry.
	Considering the small field crowding, we count B as likely physical.	Rbr2015d
