Radio observations made with Very Large Array (VLA) identified the component as a diffused jet knot.<ref name=":1" /> The radio core itself, is unpolarized.<ref name=":3" />
A radio jet is present. The jet is described as one-sided and has an extent of 10 arcseconds from the core with an orientation of -20° based on kiloparsec scale imaging. When imaged on parsec scales, the jet has the same one-sided appearance but however, also has the same position angle like the jet on kiloparsec scales, with a total extent of 15 milliarcseconds.<ref name=":3" /> Further studies also found the jet is also bending towards the direction of southwest and terminating at the position of a compact component at -95° from the nucleus region.<ref name=":2" /> The jet also contains polarization by 12 percent, with its polarized radio emission being offset from the western jet edge. The direction of the electric vector position angle is parallel to the jet.<ref name=":3" /> Further imaging also detected the galaxy contains a presence of a LINER nucleus.<ref>{{Cite journal |last1=Gonçalves |first1=A.
