A new paper on supernova 1a distance calibration 'The luminosity of supernovae of type Ia from TRGB distances and the value of H_0' - http://arxiv.org/abs/1208.5054 - brings into question the value of Ho. The authors derive a value of H0 = 63.7, considerably below the present accepted value of 73.8 derived from WMAP 7. This value is consistent with that derived by Beutler, et al [67.0] based on the 6dF survey - re: http://arxiv.org/abs/1106.3366. A lower value for Ho, of course, has far reaching implications. The fallout should be interesting.
