Photoelectric radial-velocity measurements have confirmed O. C. Wilson's finding that BD 33°2206, the secondary star in the wide visual binary ADS 8470, is a spectroscopic binary. It has an eccentric orbit with a period of 100 days. Its γ-velocity is close to the constant radial velocity of the visual primary, confirming the physical association of the stars.
