RADIOMETRIC MEASUREMENTS AT 8.5-MM WAVELENGTH WITH A 28-FOOT ANTENNA DURING DECEMBER 1962,
Abstract
A precisely calibrated 28-foot antenna, operating at a wavelength of 8.5mm with a beamwidth of 4.3 ft, has been utilized to observe emission from Venus near inferior conjuction, from the region of Taurus A and from the moon. Simultaneous observations at 12mm with the same antenna are described in a current report by the Research Laboratory of Electronics (M.I.T.). The brightness temperature of Venus, observed approximately one month after inferior conjunction, was found to be 380 degrees (+72 degrees, -34 degrees)K, in close agreement with previously reported results, Observations of Taurus A in the millimeter band have been previously reported only by Kluz'min and Salomonovich (1961) at 8mm. They observed the presence of a second source to the east of Taurus A. Some evidence was found to support the existence of this second source but the results are inconclusive. Taurus A was found to have a width of 2.4 ft = 0.5 ft. in right ascension. (Author)
