John Herschel discovered NGC 664 = h148 on 24 Sep 1830 and noted "vF; R; 20" [diameter]." R.J. Mitchell, observing with the 72" on 11 Dec 1854, recorded "S, R, bmN. Forms a trapezium [eastern vertex] with 3 stars."

400/500mm - 17.5" (11/6/93): fairly faint, fairly small, slightly elongated SW-NE, weak concentration. Nearby are a mag 15 star 50" NW and two mag 14 stars 1.8' WSW and 2' SSW.
