Abstract: We measured the magnetic field of the bright, evolved hot subdwarf HD 76431 by means of high-resolution spectropolarimetry. In contrast to previous measurements we were not able to detect a significant magnetic field. We discuss the possibility that this field may be variable. Our search for a possible companion star to HD 76431 led to inconclusive results.
