Lewis Swift discovered IC 3015 = Sw. XI-135 on 31 Jan 1898 and recorded "pB; vF * close sf; vE at 45°." His position is poor (7' too far southwest), as well as the position angle (P.A. 166°), but a star is close southeast. Herbert Howe reported in 1900 "the "* close sf" is of mag 10.5, and follows 2 seconds, 0.6' south." Howe also measured an accurate position (used by Dreyer in the IC 2).

400/500mm - 18" (5/28/06): fairly faint, moderately large, elongated 3:1 NNW-SSE, 1.2'x0.4', bulging center, even surface brightness. A mag 13 star is just off the SSE extension [45" from center]. Located 3.7' W of a mag 9.6 star and 19' ESE mag 6.8 HD 105330.
