摘　　要：The currently accepted value for the upper limit on the photon rest mass comes from a rough estimate based on the solar wind method.We reconsider this method and present a more detailed analysis of the electromagnetic fields in interplanetary space.The simple analytic expressions for the solar wind magnetic field,electric field and current are obtained with a finite photon mass.The upper limit on the photon mass is re-estimated as mγ<0.8×10^(-54) kg,which improves the current bound by up a factor of 2,and further confirms the reliability of the solar wind method.
