The discovery plate was taken with the 24-inch Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory with a 4-deg objective prism yielding a reciprocal dispersion at H-gamma of 282 A/mm. Unwidened spectra were recorded in a 120-minute exposure through a GG385 filter on a nitrogen-baked IIIa-J plate, producing an effective wavelength coverage of 3850 A-5300 A. It is thought most probable that the star is a distant halo object. Spectroscopic and photometric observations suggest that the star is of the CH class (halo population) and that it lies at a distance of approximately 30 kpc.
