John Herschel discovered NGC 2664 = h524 on 20 Mar 1830 (sweep 241) and recorded, "A neat cl of stars 9 and 10m regularly arranged about a central one (N.B. This is nearly the place of III 50, but no neb was noticed.)" At JH's position are four mag 10/11 stars with several mag 13/14 stars nearby (his position nearly coincides with a mag 10 star at 08 47 13.8 +12 36 14).

Karl Reinmuth, in his 1926 photographic survey based on Heidelberg plates, adds "pS Cl of a few st 10...15." Harold Corwin notes that Villanova (2004, A&A, 428, 67) concludes this is a random enhancement of field stars and not a cluster. The position given here corresponds with the center of this asterism. Listed as a nonexistent cluster in RNGC.

400/500mm - 17.5" (2/8/97): poor scattered asterism of 10 stars in a 5' region dominated by four mag 10-11 stars in a "kite" asterism with pairs of sides 2' and 3'. Only noticeable at low power and does not resemble a cluster, although the fainter stars are nicely spaced around the bright stars. A fainter group with 4-5 mag 13 stars lies 5' NW. Located ~16' E of NGC 2661.
