Add to ORKGWe have determined the relativistic light deflection of the quasar J0842+1835 as Jupiter passed within 3.7' on 2002 September 8, by measuring the time delay using the VLBA and Effelsberg radio telescopes at 8.4 GHz. At closest approach, General Relativity (GR) predicts a radial (static) deflection of 1190 microarcsec, and tangential (retarded) deflection in the direction of Jupiter's motion of 51 microarcsec. Our experiment achieved an rms position error of <10 microarcsec, and measured this retarded deflection to be 0.98 +/- 0.19 (rms error) times that predicted by GR. The increase positional accuracy for this VLBI phase referencing experiment was achieved by using two calibrator sources. Comments on the interpretation of this experiment a...
