I just found what looks like an uncatalogued polar-ring galaxy in HSC while classifying the Galaxy Zoo citizen science project.Look closely for the faint blue ring

This one seems to have the appearance of a polar-ring about it, but based upon poor image quality, it has a chance it could be an overlap… Still routing a polar ring

agree ~ p-r

Found another polar ring. It seems like a current interaction event is happening and forming a ring around it.

This looks like the remnants of a minor merger (e.g. a stellar stream)

yeah! That could be possible. There are other objects similar to this, such as interaction features, etc.

Are we including them in the NPA, or keeping it as a different catalog?!

I split the candidates into five categories:

A - True PR
B - Likely PR
C - Possible PR
D - Unlikely a PR
E - Rejected candidates

Beware that the list has been relocated and is currently under construction. Cross-IDs and detailed morphology of the galaxies and structures will be included.

Thanks for the update.

Possible PR?

interacting SBb barred-spiral

Both look like good candidates.

Wow, not listed in the NPA. I will add it to the list.
