1 A Possible Super Hubble Bubble Brent Tully, Institute for Astronomy, University of Hawaii

2 A Possible Super Hubble Bubble Brent Tully, Institute for Astronomy, University of Hawaii Oops! 2 sigma result - forget it

3 Cosmicflows- 2 Integration of distance measures from multiple sources, establishment of the SNIa scale and H 0 Extragalactic Distance Database http://edd.ifa.hawaii.edu Revised I-band Luminosity-Linewidth Correlation (Tully & Courtois, in press)

4 CF2: SNIa Calibration and H 0 combine 3 FP sources combine 2 TF and 3 FP with CF2 zero point Cepheid, SBF, TF, FP set SNIa scale with CF2 zero point

5 CF2: SNIa calibration and H 0 (continued) UNION2 SNIa sample shifted to CF2 zero point. Fit over interval 0.03 < z < 0.5 H 0 = 76.3 +-3.8 km/s/Mpc Courtois & Tully, in press
