The host is listed as a possible cluster member by Spinrad et al. (1985).

This is one of the most distant and powerful giant radio galaxies in the LRL sample. The structure is a typical classical double. Higher resolution (but undersampled) observations by Neff, Roberts & Hutchings (1995) show that the south hotspot is double, with the more compact component leading. The core is coincident with the optical identification, marked on our image by a small red cross near the inner edge of the S lobe. Neff et al.'s near-simultaneous measurements at 6 and 20 cm show that the core has a steep spectrum.

Our image was made using a combiniation of unpublished VLA data, observed in B-configuration by J. P. Leahy and in C-configuration by P. P. Kronberg.
