Radcliffe spectra of this star in 1961 confirmed Luyten's suspicion on the basis of colour and proper motion that this object is a bright white dwarf. The profile of Hγ was found to be closely similar to that of o2 Eri B. Hill and Hill have published photometry yielding V = 11.40. The only known white dwarfs brighter than this are Sirius B, o2 Eri B, Procyon B, Feige 34 and CD −38° 10980.
