H 0323 + 22, if galactic, is unprecedented in its radio and X-ray properties. A deep R-band image of the source shows it to be spatially extended, with significant light detectable 10 arcsec from the bright nucleus, thereby implying, in the event that it represents an underlying galaxy, that its distance is in the 0.5-1.5 Gpc range and that its radio, optical, and X-ray luminosities are typical of other BL Lac objects. The G star-like absorption spectrum, however, then remains to be explained. Because the two closest bright optical objects also exhibit G star spectra, it is suggested that the Doxsey et al. (1983) G spectra are due to misidentification of the object. H 0323 + 22 is both extragalactic and probably similar to other X-ray selected BL Lac objects.
