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.
