Max Wolf discovered IC 3874 = W. VI-90, along with several other faint IC galaxies within AGC 1638, on a Heidelberg plate taken 27 Jan 1904. He reported "vF, vS, iF, * 15 sf 0.3'."

900/1200mm - 48" (4/2/11): faint, very small, round, 12" diameter. Similar IC 3874 lies 1' WNW. This pair of galaxies is at the east end of 5' circlet of 6 IC galaxies on the west side of AGC 1638. A mag 16.3 star lies 22" SE of center.
