Arp 49 (NGC 5665)

Arp 49 is the first of Dr. Arp's class Spirals with Small High Surface
Brightness (HSB) Companions on Arms. There are a couple of knots on the
east edge which
could be companions but it's hard to tell. I
don't find it really obvious on the Atlas image, either. The note says
"appearance of wake from stellar object in E arm" and that does not help much.
