In a 33" an observation of mine from about a year ago of CGCG 315-43 causes me to wonder in what catagory this ring was placed. It seems to be in a group from our 2D view of the area. Here is the note taken:
CGCG 315-43 Type: Glxy Position: 12 32 05.2 +66 24 10 Con: Dra

PostNote followup: Found it on page 206 of steve's link to the paper on rings. My connection timed out so I could only see it in a small picture to the left but the field of 3 galaxies was distinct enough to lead me to believe it is in that paper on page 206. MegaStar also refers to it as VV788
