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 wsq m cps and 290 100 x 10 to- 26th power wsq 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 wsq 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 A35Gc. The 35 Gc position of Tau A and Sgr A coincided, within the limits of the measuring accuracy 3s R.A. and 1 Dec., with lower frequency source positions. Author
