    NVSS

    Any thoughts?

    #SDRAGN candidate! 😮

    OK, the extended (NVSS) radio emission is certainly not, by any stretch, describable as "lobes", but I think the host is zsp 0.122 SDSS J083350.03+150122.9; it's a slightly below threshold FIRST source, and obvious in NVSS too:

    Visually, you'd guess that it has an AGN; the SDSS spectrum confirms this:

    The extended, greenish "halo" around the obvious Eos (more likely highly inclined than truly edge-on) makes this a very strange galaxy, IMHO.

    So, some kind of #NAT or #WAT, possibly faint because it's fading ...

    I think the almost #hourglass FIRST source in the center (FIRSTJ083351.3+150228) is unrelated; it's far, far in the background (#noIR #nooptical).

    Reminds me a bit of ARG0003o4w, with host SDSS J023832.67+023349.1 (discovered by Tony Wei):

    Here's an NVSS overlay. Don't know if this helps with a host, as there could be a multitude to choose from in ALLWISE, and whether the lobes, emissions to the N and NE are connected to the centre lobe.

    And here's the above image with the First contour included. There is an ALLWISE source associated with this First lobe, ALLWISE J083351.32+150230.8, which is aligned more to the centre N of the emission.
