Abstract : During its occultation by the sun in October 1969, the position of the radio source 3C279 was interferometrically monitored to determine the deviation of its 9.602-GHz radiation in the solar gravitational field. Rapid instrumental calibration and negligible coronal diffraction enabled the measurement of a General Relativity deflection of 1.77 plus or minus 0.20 seconds at the limb of the sun. This is in close agreement with Einstein's prediction. (Author)
