Query: The Hubble Constant from SZE Measurements in Low-Redshift Clusters   We present a determination of the Hubble constant from measurements of the
Sunyaev-Zeldovich Effect (SZE) in an orientation-unbiased sample of 7 z < 0.1
galaxy clusters. With improved X-ray models and a more accurate 32-GHz
calibration, we obtain H_O = 64+14-11 +/- 14_sys km/s/Mpc. for a standard CDM
cosmology, or 66+14-11 +/- 15_sys km/s/Mpc for a flat LambdaCDM cosmology. The
random uncertainty in this result is dominated by intrinsic CMB anisotropies,
and the systematic uncertainty is chiefly due to uncertainties in the X-ray
spectral models. The implications of this result and future prospects for the
method are discussed.
