Arp 307 (NGC 2872, 73, & 74)

  Arp 307 is another member of the Double Galaxies class.  The Atlas note says "possibly not interacting".  The large E-type galaxy is NGC 2872, the SE spiral is NGC 2874, and the smallest of the group, to the NE, is NGC 2873.  It looks like there is a galaxy cluster occupying the entire SW half of the field but NED does not list anything except a triple galaxy 1.2' S of the bright star in the NW corner.
