GD 358 is a variable white dwarf star of the DBV type. Like other pulsating white dwarfs its variability arises from non-radial gravity wave pulsations within itself. GD 358 was discovered during the 1958–1970 Lowell Observatory survey for high proper motion stars in the Northern Hemisphere. Although it did not have high proper motion it was noticed that it was a very blue star and hence might be a white dwarf. Greenstein confirmed this in 1969.In 1968 Arlo U.
