Scientific paper

The discovery of a new white dwarf about 20 arcsec east of the A-type
star HD 74389 is reported. A physical association is not highly
probable. Because of the importance of binaries with degenerate
components, attention is drawn to this star in the hope of stimulating
further observations.
