摘　　要：The very long baseline interferometry result of a superluminal radio source PKS 0420-014 at 5 GHz with Shanghai(China),Urumqi(China),Noto(Italy),and HartRAO(South Africa)telescopes is presented.Proper motions of the relativistic jet components in the source are calculated.Based on the Self-Compton emission in a uniform spherical model,the beaming parameters of the source are estimated.The results show that PKS 0420-014 has a high Doppler factor of 9.3,a Lorentz factor of 6.5,and a small angle of 5.5°to the line of sight.
