We 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 μarcsec, and tangential (retarded or dynamic) deflection in the direction of Jupiter’s moti...
