Lewis Swift discovered NGC 5415 = Sw. III-78 on 8 Apr 1886 and recorded "eF; vS; R; forms a triangle with 2 F st." His position is roughly midway between CGCG 336-032 and fainter CGCG 336-035, but Harold Corwin notes that Swift's comment "forms a triangle with 2 F stars" applies to brighter CGCG 336-032.

400/500mm - 17.5" (6/7/97): faint, very small, round, 20" diameter, weak concentration. Forms east vertex of a nearly equilateral triangle with two mag 13/14.5 stars ~1.5' W and a similar distance NW.
