Francis Leavenworth discovered NGC 6931 = LM 1-232 on 4 Jun 1886 and recorded "mag 15.0, 0.6'x0.2', E 120°, gbM, divided into 2 parts?" His rough position (nearest minute of RA) is 20 seconds east and 1.5' south of MCG -02-52-016 = PGC 64963 and the position angle matches. Bigourdan, on 31 Jul 1888, and Herbert Howe in Denver measured an accurate RA (given in the IC 2 Notes). Howe noted "though this is very small, it is much elongated at 120°. At times it appeared to have condensation near each extremity, but the seeing was not very good."

400/500mm - 17.5" (9/15/90): very faint, very small, elongated ~E-W, faint stellar nucleus. A mag 15 star is off the NW edge.
