Arp 69 (NGC 5579)

  Arp 69 is by far the largest in a field packed with galaxies.  It is another of Arp's class Spirals with Small HSB Companions on Arms.  The Atlas note is "three-armed spiral".  It is my guess that the companion is the small galaxy to the south, about halfway to the star.  However, I can't see on my image that the arm extends all the way to the companion, and I can't trace it in the Atlas image either.  But in many cases, the original plates probably show subtle features and details that can't be seen in the scanned images.
