The paper discusses recent measurements of the anisotropy of the microwave background radiation of the local Hubble flow which suggest that the local group of galaxies has a motion of 300-500 km/s directed toward Virgo. If this velocity is generated by the Virgo supercluster, it provides an effective test of the cosmological parameter omega. The mean overdensity toward the Virgo cluster was computed to be about 2.0 plus or minus 0.03 based on a catalog of redshift data complete to m(b) = 14.0. When combined with a nonlinear spherically symmetric flow model around Virgo, the omega was 0.4 plus or minus 0.1; thus the measured mass-to-light ratio of the universe continues to rise with increasing scale size of measurement.
