Lewis Swift discovered IC 2006 = Sw. XI-63 on 3 Oct 1897 and logged "pB; S; R; * near nf; double star sp." His RA is 24 seconds too small, but the identification is certain.

300/350mm - 13.1" (1/18/85): fairly faint, fairly small, slightly elongated ~N-S, diffuse but contains a very small brighter core, possible stellar nucleus. Located at the east edge of the Fornax I cluster.

600/800mm - 24" (1/1/19): at 260x; moderately bright, moderately large, irregularly round, 1.2' diameter, well concentrated with a bright core that increases to the center, fairly uniform halo. Mag 9.9 HD 24695 (very wide double) lies 5.4' SW. A mag 11.5 star is 2.7' ENE.
