MILLIMETER STUDIES IN RADIO ASTRONOMY.
Abstract
The investigations of 94 Gc solar emission during the 20 July 1963 solar eclipse were restricted by inclement weather. No systematic limb brightening was observed; radiation approximately 6 seconds after occultation, was observed from the southeastern limb at the position of a prominence. Tau A (35 Gc) and Sgr A (35 Gc) flux densities were 420 = 60 x 10 to(-)26th power w/sq m /cps and 290 = 100 x 10 to(-) 26th power w/sq m /cps, respectively. The flux density of Tau A (70 Gc) interpreted from an antenna temperature signal to noise ratio of approximately 2 to 1 was 790 = 450 x 10 to(-) 26th power w/sq m /cps. Observations of 94Gc of Sgr A, having a calculated antenna temperature standard deviation of 0.2C, revealed no source of radiation at the central position of Sgr A(35Gc). The 35 Gc position of Tau A and Sgr A coincided, within the limits of the measuring accuracy = 3(s) R.A. and =1' Dec., with lower frequency source positions. (Author)
