Gravitational lensing by a spinning deflector in translational motion relative to the observer is discussed in the weak field, slow motion approximation. The effect of rotation, which generates an intrinsic gravito‐magnetic field, separates from that due to radial motion. Corrections to the lens equation, deflection angle and time delay are derived.
