UK Schmidt image, λ4680A, width 2 arcmins.
Notes
A probable CSS quasar; there is some extended radio emission adjoining the strong core in the VLA images, and a much fainter lobe-like structure ~16” to the SE (Morganti et al. 2003; Reid, Kronberg & Perley, 1999, ApJSS, 124, 285).
The optical spectrum of this quasar shows strong broad emission features (including FeII blends), blue continuum, and relatively weak [OIII]λλ 5007, 4959 emission lines.
