Two small blue arcs: a lensed galaxy?

Two small what look like blue arcs. Is this a lensed galaxy and if so, is it a known one?

Or are these features two areas of starformation?

SDSS image, not that convincing…

Hi,

Interesting… you don’t normally see star formation knots in smooth elliptical galaxies like this, and they tend to be bluer and look more disturbed. It could be two background galaxies; they would be lensed somewhat from galaxy-galaxy lensing. I would guess not a strongly-lensed double-image single background object; those tend to be more elongated, and would be at smaller radius (the Einstein radius). Just a guess.

William Askew told me this galaxy is in the Abell 1882 cluster.
