This giant radio galaxy is one of the objects listed in 3C but not in 3CR, probably because it was slightly resolved in that survey. The accurate 4CT flux density is clearly above the sample limit.

A faint jet is visible, entering the northern lobe.

The compact source just south of the southern hotspot complex is almost certainly an unrelated background object.
