Here's ARG0001r8j, a #triple, or #doublelobe with a #compact radio lobe in the centre of the #doublelobe emission.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread.The host appears to be SDSS J084621.28+292937.3, a very faint galaxy, which has a DR9 z_ph=0.258, and is #green. It has an ALLWISE reference of ALLWISE J084621.33+292937.4, and there are NED and SIMBAD references for the host being SDSS J084621.28+292937.3.
Here's a zoomed in image of SDSS J084621.28+292937.3.
The First image below does raise the question of whether this is a #triple, or a #doublelobe centred on SDSS J084621.28+292937.3 with a #compact lobe in the centre of the emission with #noir host. The centre lobe is somewhat less luminous in First, slightly off centre from the other lobes, and seems partly extended to the NW. Furthermore, the centre lobe is not aligned with the SDSS J084621.28+292937.3.
Wise bands 1 and 2, and DECaLS are not much help here for possible alternative hosts for the #compact. DECaLS image below. Any views?

How about a fairly symmetrical #doublelobe, with the host as you've identified (and which may have some faint emission), and an #overlap #compact? That unrelated source would very likely be waaaaay in the background; its host doesn't show up in DECaLS, WISE, or SDSS ...

Agree. Thanks.
