This elliptical shows an unresolved nucleus. The image shows a faint jet about 6 southwest of the nucleus identified by [Chiaberge et al.2005] as the infrared counterpart of the brightest region of the radio jet. Chiaberge et al. find that the infrared emission dominates the spectral energy distribution of this jet. An elliptical companion is visible to the north. A bright unresolved source is present north of the core. This object lies on the radio jet axis but is not associated with any of the radio features. In the optical image of [de Koff et al.1996] it appears as a diffuse source. It is possible that this object is an infrared-bright background galaxy.
