Wilhelm Tempel discovered NGC 4562 in 1882 while observing NGC 4565. In the text portion of paper V (AN 2439) he simply mentioned another nebula was found south preceding NGC 4565, though no offset was mentioned. Dreyer gives a very rough position in the NGC. The only galaxy in this location that Tempel might have picked up is UGC 7758 = PGC 41955. The RNGC also calls this galaxy NGC 4565A.

Due to the poor NGC position, this galaxy was found on Crossley plates taken at Lick Observatory in 1898-1900 and catalogued as a new nebula (#508 of 744) in the 1908 Publications of Lick Observatory, Vol VIII.

400/500mm - 17.5" (5/13/88): faint, fairly small, elongated SW-NE, even surface brightness.

17.5" (3/23/85): faint, small, elongated SW-NE, low even surface brightness, visible with direct vision. Elongated at a right angle to NGC 4565 13' NE. Located just south of a string of five mag 10-12.5 stars of length 11' oriented N-S.
