CGCG calls this object a "Triple system"; UGC says "double or triple"; Mrk says "two doubles"; Zwicky described it as a "blue post-eruptive quadruple of two bar-shaped and two spherical compacts" and V-V called it a "nest of six compact galaxies". HST image shows two interacting galaxies, both with starburst regions.

Guillaume Bigourdan discovered IC 2184 = Big. 390 on 24 Jan 1900. The IC position is nearly 11' too far southeast. Corwin re-reduced his original offsets, though, and they match this multiple system. CGCG (330-039) doesn't associate the IC identification.

600/800mm - 24" (2/5/13): at 375x, fairly faint, fairly small, irregularly round, ~25"x20", irregular surface brightness but no resolution into components. Perhaps higher power is needed to see the two main components.
