Arp 227 (NGC 474 & 470)
|
|
Arp 227 is the first member of the class Concentric Rings. The Atlas note
says "position of spiral.SO is E and a little N. Very faint rings extend
to a diameter of 7'." The large primary is NGC 474 and the spiral to the
west is NGC 470. Megastar shows a double quasar just southeast of NGC 470.
It may be the unequal pair of starlike objects about 1' west of the brighter
star. As far as I can determine, the "jet" from the southwest edge of NGC
474, just below the same star, is either an artifact or solar system object. I can find no hint of it
in the Atlas image or the DSS.
