Lewis Swift discovered NGC 3487 = Sw. III-58 on 5 Mar 1886 and logged "eeF; pS; R; e diff; in vacancy." His position is 35 sec of RA west of UGC 6092.

400/500mm - 18" (5/31/03): very faint, fairly small, very elongated 3:1 NNW-SSE, 0.7'x0.25', nearly even surface brightness. Arp 198 = VV 267 lies 15' NW.

600/800mm - 24" (3/28/17): at 260x; fairly faint, fairly small, elongated 5:2 NNW-SSE, ~45"x18". Appears brighter along a thin spine of the major axis.

Arp 198 = UGC 6073, an overlapping pair consisting of face-on spiral and a thin edge-on that extends directly to the nucleus of the face-on, lies 15' WNW. At 260x and 375x, it appeared as a very faint, fairly small, very elongated glow, ~0.4'x0.1', extending to the southwest of a mag 12.3 star. The pair has an unusual "spike" appearance, with a very small "knot" (core of VV 267a = UGC 6073b, the face-on spiral) at most 10" diameter at the northeast end close to the mag 12 star [28" SW of the star]. The spike or tail (VV 267b = UGC 6073a) extends southwest with the combined glow collinear with the star!
