  The SETI Ellipsoid is a geometric method for prioritizing technosignature
observations based on the strategy of receiving signals synchronized to
conspicuous astronomical events. Precise distances to nearby stars from Gaia
makes constraining Ellipsoid crossing times possible. Here we explore the
utility of using the Gaia Catalog of Nearby Stars to select targets on the SN
1987A SETI Ellipsoid, as well the Ellipsoids defined by 278 classical novae.
Less than 8% of stars within the 100 pc sample are inside the SN 1987A SETI
Ellipsoid, meaning the vast majority of nearby stars are still viable targets
for monitoring over time. We find an average of 734 stars per year within the
100 pc volume will intersect the Ellipsoid from SN 1987A, with ~10% of those
having distance uncertainties from Gaia better than 0.1 lyr.
