We present here new astrometric measurements of Algol's position made with Very Long Baseline Interferometry. Using these measurements, along with a new estimate of the node of the inner binary and other orbital elements from the literature, we compute a new proper motion, with uncertainties six times less than those of Hipparcos. We compute the trajectories of Algol (using the new proper motion) and of Gliese 710, and discuss the various sources of uncertainty. We nd that it is essential to…
