Accurate distances from nearby stars from Gaia make possible elliptical transit times. Here we explore the usefulness of using the Gaia list of nearby stars to select targets in the SN 1987A SETI Ellipsoid, as well as the Ellipsoids defined by 278 classic youngsters. Less than 8% of the stars in the 100-pound sample are inside the SN 1987A SETI Ellipsoid, which means that the vast majority of nearby stars are still viable targets for tracking over time. We find that an average of 734 stars per year within the volume of 100 pcs will intersect the Ellipsoid from SN 1987A, with ~ 10% of them having distance uncertainties from Gaia better than 0.1 lyr.
