The perturbations due to the solar radiation pressure forces on the Earth's artificial satellites have been given taking into account the Moon's shadow and pre-shadow effects. The formulae are convenient when the perturbed forces are obtained by numerical methods. The study shows that the cylindrical model of the shadow is insufficient and that the conic shadow model including the pre-shadow gives more accurate results.
