We present a 40GHz ( 7.5 mm ) raster scan image of a 3.6 \arcdeg \times 2 \arcdeg region centered on the low redshift ( z = 0.055 ) cluster of galaxies Abell 3667 .
The cluster was observed during the Antarctic winter of 1999 using the Corona instrument ( 15.7 \arcmin FWHM beam ) on the Viper Telescope at the South Pole .
The Corona image of A3667 is one of the first direct ( i.e . rather than interferometer ) thermal Sunyaev-Zel ’ dovich effect images of a low redshift cluster .
The brightness temperature decrement at the X-ray centroid ( 20 ^ { h } 12 ^ { m } 28.9 ^ { s } , -56 \arcdeg 49 \arcmin 51 \arcsec J2000 ) was measured to be \Delta T _ { CMB } = -154 \mu K .
We have used the 40GHz map of A3667 in conjunction with a deep ROSAT PSPC ( X-ray ) image of the cluster , to make a measurement of the Hubble Constant .
We find H _ { 0 } = 64 ^ { +96 } _ { -30 } km s ^ { -1 } Mpc ^ { -1 } ( 68 % confidence interval ) .
Our H _ { 0 } calculation assumes that the cluster can be described using an isothermal , tri-axial ellipsoidal , \beta -model and includes several new analysis techniques including an automated method to remove point sources from X-ray images with variable point spread functions , and an efficient method for determining the errors in multi-parameter maximum likelihood analyzes .
The large errors on the H _ { 0 } measurement are primarily due to the statistical noise in the Corona image .
We plan to increase the precision of our measurement by including additional clusters in our analysis and by increasing the sensitivity of the Viper SZE maps .
