Theory of the physics of the early hot universe leads to a prediction of
baryon acoustic oscillations that has received confirmation from the pair-wise
separations of galaxies in samples of hundreds of thousands of objects.
Evidence is presented here for the discovery of a remarkably strong individual
contribution to the baryon acoustic oscillation (BAO) signal at z=0.068, an
entity that is given the name Ho'oleilana. The radius of the 3D structure is
155/h_75 Mpc. At its core is the Bootes supercluster. The Sloan Great Wall,
CfA Great Wall, and Hercules complex all lie within the BAO shell. The
interpretation of Ho'oleilana as a BAO structure with our preferred analysis
implies a value of the Hubble constant of 76.9+8.2-4.8 km/s/Mpc.
