    Could the bright ETG in the centre be lensing a background galaxy? SDSS J114723.30+333153.5 Z_sp=0.212 has an adjacent arc with three components but I don't see anything opposite.

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) contours derived from the FITS file produced using SkyView with Python code described in this RGZ Talk thread. Image center per the ARG image (left; J2000.0). "z_ph" is an SDSS photometric redshift of the galaxy in the center.

    SDSS J114723.30+333153.5 is DR7 ObjId 587739405705478208, DR8 1237665126930382954. It was noted as a possible sgl (strong gravitational lens) by super-zooite gumbosea, on May 27, 2008. It is one of several "almost certain" sgls in Wen+ 2011*.

    Too bad gumbosea didn't get a chance to publish his findings in a peer-reviewed journal. 😦
