Albert Marth discovered NGC 7700 = m 584, along with NGC 7699, on 18 Nov 1864 and noted "vF, eS, stellar. (not far from [NGC 7701])." His position is accurate. The identifications for NGC 7700 and[NGC 7701 are reversed in the pre-publication version of the ESGC and this error is repeated in the RC3, PGC and secondary sources such as the first edition of the Deep Sky Field Guide and WikiSky. See Corwin's notes.
