Candidate unreported gravitational lens (cluster)

Hello DECaLS and a Happy New Year!

With regards to the red arc;

Possible gravitational lens, not mentioned in hundreds of ‘lens’ and ‘lens system’ objects in Simbad, not in NED.

Love to get your opinion on this one. I know they are usually blue not red, but not familiar with lenses in DECaLS.
