  The magnetic field $h_z$ of a moving Pearl vortex in a superconducting
thin-film in $(x,y)$ plane is studied with the help of time-dependent London
equation. It is found that for a vortex at the origin moving in $+x$ direction,
$h_z(x,y)$ is suppressed in front of the vortex, $x>0$, and enhanced behind
($x<0$). The distribution asymmetry is proportional to the velocity and to the
conductivity of normal quasiparticles. The vortex self-energy and the
interaction of two moving vortices are evaluated.
