Abstract
6 Ursae Majoris is a bright (5 1/2(m)) Star of a type (G6 III) ideally suit ed to radial-velocity measurement, and it shows velocity variations of more than 25 km s(-1); it has been known as a spectroscopic binary for nearly 8 0 years, and yet its orbit has never been determined until now. The period is very close to 1900 days, and the orbit is of high eccentricity (0.7). Th e mass function suggests that the secondary could well be a main-sequence F star.
