From the Suggestions for RGZ Objects to show with detailed FIRST contours overlaid on SDSS images thread, started by WizardHowl:
http://radiotalk.galaxyzoo.org/#/subjects/ARG0001gr4 corejet or two compact sources? nearby disk galaxy
Some more, fairly simple, analysis would likely show the (almost) Eos' nucleus is at the same place (on the sky) as the centroid of the central (but slightly weaker) FIRST radio source. The other FIRST radio source? My guess would be "more detailed observations required to rule in/out it being associated with UGC 6397" 😄

Here's a very similar overlap image, with the addition of z_sp (of the galaxy in the center) on the image itself:

Just a thought: could this be a supernova remnant in UGC 6397 (I mean the compact source to upper-left of the AGN)? Or is it too strong for that? From FIRST, the peak signal strength here is 3.14 mJy/beam and UGC 6397 has Z_sp=0.02083. That compact source is off the main disk plane but right in line with another faint plane of stars tilted at about 45 degrees to it. Given the disruption to this galaxy, I'm not sure whether a supernova remnant, corejet or background source is the more likely scenario...

@WizardHowl has described the possibiities. This needs to be on the list for higher resolution data.
