Abstract
The visual binary Psi Sagittarii (ADS 12214, HR 7292) is a spoctroscopic triple system with orbital periods of 10.78 days and 20.0 years. Periastron passage in the long period orbit occurred on JD 2442410 ± 30 days. Masses derived from the parameters of the spectroscopic and visual orbits are 2.7 m⊙ for the visual primary, 2.1 m⊙ for the short period pair primary, and 1.7 rn for the short period pair secondary. The distance to the system is 100 parsocs. The orbital inclination of the close pair is nearly the same numerically as that of the visual orbit. Suggested spectral classifications indicate that all three components have evolved off the main sequence. Mass exchange in the close pair has not yet occurred.
