Arp 257

  Arp 257 is the first member of Dr. Arp's class Irregular Clumps.  His Atlas note was "galaxies joined by segment of thin arc".  That is just barely detectable in my primary image, but can be seen easily in the high-contrast 2x detail image below.  That image shows the complex knots and streamers surrounding this strange object.  Also shown is a low-contrast 4x image of the multiple core of the S galaxy.

The southern galaxy is cataloged as UGC 4638 and the northern as MCG +0-23-6.
