    Youre fast!

    Thanks I wasn't aware of this paper, made with GalaxyZoo classifications among other sources. I now see that it's AGZ000atcu in the Polar Ring Collection

    It also seems SPRC-7 from this paper is AGZ000axry now in the Collisional Ring Collection ( but among the 'Best Candidates' in the Polar Ring Paper mentioned above)

    By the way is there an accepted definition of polar rings, can't find if it excludes polar dust lanes instead of stars and gas.

    Wiki definition:

    A polar-ring galaxy is a type of galaxy in which an outer ring of gas and stars rotates over the poles of the galaxy [1].
