what is the earliest/most distant restarted source?

sharqua has commented on what might be a very unusual radio source. I think all the radio emission here comes from the IR source at image centre, which is faint and has no optical host suggesting it is very distant (I'm thinking beyond z~0.7 at least). FIRST shows hotspots that look like a #restarted #doublelobe but I don't remember seeing one potentially so distant before. Granted, the image in radio might not have enough resolution to be certain of the lobe geometry but this certainly seemed worthy of highlighting to the SCIENTISTS.

This is a curious one, but I'd be hard pressed to make an ID. What we'd need are radio spectra to see which component was "flat", which would indicate the location of the black hole/AGN. I don't see the "IR source at image center"?

in response to DocR's comment.
The IR source is slightly above the brightest part of the radio and is partly obscured by the contours (thus in between the two central sources of radio emission). In WISE band 1 it is very faint and slightly extended (in N/S direction) suggesting a blend of two very faint sources at/close to the limit of sensitivity. The co-ordinates are RA: 215.872589 DEC: 17.874749. The feature is visible in band 2 also but seems less extended there.
