The temporal variation of the circular polarization observed in the magnetic white dwarf G195--19 is interpreted in terms of an oblique rotator model. The peculiar behavior observed in red light strongly suggests the presence of a spot on the surface of this star. A model based on this assumption is found to be consistent with observations. (AIP)
