Corwin's Notes
=====
NGC 3099. Like NGC 3088 (which see), neither Herschel noted this as a double
galaxy. It is, in fact, not -- the companion (itself a pair) is simply a
member of the same group. Holmberg was the first to note the companion; it is
Holmberg 160b, with NGC 3099 being Holmberg 160a.
Steve's Notes
=====
NGC 3099
17.5" (4/9/94): very faint, small, round, easily held with direct vision, very weak even concentration down to a slightly brighter nucleus. A mag 15 star is 2.7' N. Located 17' WNW of mag 7.6 SAO 61840. Forms a double system with MCG +06-22-058 = Ho 160b 1.4' NW.
