Arp 259 (NGC 1741 group)

  Arp 259 is in the Irregular Clumps class.  It's the group just south and east of center.  The Atlas note is "material extends SE toward peculiar round spiral".  The brightest clump is NGC 1741; all of the galaxies are part of Hickson Galaxy Cluster 31.  The object just over 2' southeast which looks like a slightly fuzzy star is IC 399.  It isn't part of the Arp field but is probably the round spiral that Dr. Arp mentioned in his note.

The 2x detail image shows some of the internal structure better.  NGC 1741 has at least three, maybe four, nuclei, or consists of overlapping galaxies.
